Mechanical Engineering Kinematics Project

[rudranand]

hi dude i'm doing this project now i want dimensions and design mail me at rudranandmech@gmail.com,pls sir

[anonymousmagi149]

nice work!

[TheKalapacsos]

this sound could be creapy at night... alone...

[ZEINSTAIN2011]

nice one!check my robotand other stuff!

[basahr1]

what is the thickness of material used in frame and mechanism

[flaminio7]

shame on you! You have such awesome machines (mills, lathes an so on) and you made a so careless work! At least you shoud taper the legs!

[skyrbn]

nice one



[tuloski]

What a smooth path...

[TheDarqTurk]

It aint looks o necessary.

[tld5500]

Maybe instead of square edged feet, calculating a radius? These feet seem to lift the entire machine when moving

[217andersen]

..............................­........

[Cam5X5]

wouldn't it worked better if you had some rubber on the edges of each feet?

Grip?

[c00lCactus8D]

My core grades right now: Biology-E Health-E, Economics-E, English-E,

Math-A, If I pass all my grades this year and next year, the next two years I can go to a tech center for half my school days every day and will be learning more on that and im interested in it. I have untill next weak to pass all my grades before the marking period ends. Wish me luck :(

[anatete1]

@c00lCactus8D Aw :\ good luck, do your best.

[c00lCactus8D]

@anatete1 Lmao, barely passed xD Biology-C Health-D Econ-D English, D-, Math-A :)

[MARKTSACKde]

you made a computermodel for that??? - LOL

[nik3b0rasto]

hey guys i liked this project of urs..our group of engineers have decided to make some modifications in this design n so we want ur recommendations and ne suggestion of what kind of things we should be concerned with while working with this model...we will be looking forward to hear from u..thank u..

[Aeleita1]

I can see how it works...

[Aeleita1]

I can see how this would work...

[SAM46323]

could u please tell me any advantage of ur machine dude

[kumar7613]

awesome mechanism usage ..really good guys

[francisdaimler]

Please watch: Desert Robo Tank

[Thescaverda]

@lob413 from what university are you??



[Thescaverda]

lob413.. it is really a nice design

[JOEGUY92]

The fact it took 6 Mech Engineers to make this makes me question whatever University you go to...

[ajleonor826]

great stuff!!! we will have the same project like you guys did but we will add more stuffs/features on it.. thanks for posting this.. it's definitely a head start for us!

[Alexander85074]

hey man no need for ur dimentions !!!!!!!!!!

we done it man

[Alexander85074]

@Alexander85074 have a look

[navedahmid]

great idea by moving through legs...but the design og legs should be improved....well done

[navedahmid]

great idea by moving through legs...but the design og legs should be improved....well done

[korin300]

Was this in college or high school??

[frisc45]

how about putting some rubber grips on the metal where contact is made ?

[JalmarEst]

i think this drill wasn worth to brake down for this

[lob413]

@JalmarEst It was a donation from an internship. I calculated the torque required to turn the legs, geared it down, and hoped it would work. It served it's purpose well.

[Prankster10001]

@lob413 It seems to me that you tried to Theo Jansen it up but failed..

[TheJelloSheriff]

@JalmarEst Philistine.



[Claews]

It looks like you needed to gear the device some more, the engine looks to be in pain

[lob413]

@Claews It was. The axles weren't perfectly aligned, the chain tension wasn't supported by bearings, and nothing was lubricated. All three of those factors drastically increased friction. I'd do it differently now. You live and learn I guess.

[MsDissonant]

Very cool. :)

[AunShovah]

well thats cute

[OregonDARRYL]

Round the feet and put some rubber over the edges and that thing will run...

[bnewton81]

The first Terminator.

[wilsocn]

@bnewton81 I can see why those chose to forgo the movie on this one.

[swss12]

did that really require a welder?

[cakefarts]

@lob413 i'm sure nobody wants to build this to cheat on an obscure fucking engineering exam. you don't just put shit on youtube for a pissing contest and then be a bitch when people ask questions.

[cakefarts]

"I'm sorry, but I will not share the details of this project beyond what you see in the video because that could be considered academic misconduct."

you are a faggot.

[kaizer4519]

it only needs a brain but that is simple with a microcontroller

[NeKoShinn666]

GOOD WORK SOLIDER NOW STRAP SUM C4 ON THAT BABY N SEND IT TO IRAQ!!!

[MrFrankieya]

impressive mate!!!!

[9960115683]

which song?

[9960115683]

which song?

[InfiniteCemetary]

Nice!

[chargedUAV]

im 15 and i could of done better......

you need independant motors for either side so it can turn, though personally i would use servos and make proper legs....

and if you made hexapod from scratch i seriously doubt you would fail....

[wecantsee]

Not so different from a vehicle moving back and forth.

[3Target33]

you should of added little rubber buds on the legs

[beetech]

unique moving

[campauchicken]

oh man that was the smallest welder ever.

[A1z1u1L]

hahaha awesome!!!!

[MrGameboy1989]

whats the name of the song

[lob413]

@MrGameboy1989 Walk this way

[WILD4X4D]

@lob413 very apropreate song :)

[013dirtdiver]

@MrGameboy1989 The Aerosmith version is Insane dude!!

[BrutusDA]

@MrGameboy1989 Lol. How do you not know this song??????

[TheTuxedomazk]

hey, can i know that is this project consists of slider cranks, straight line motion with 4-bar linkage and insect leg?

[SecularTechnology]

AWESOME!!

[WolfOwlism]

You really shouldn't have the motor directly linked at its end to a gear, it burns the motor up.

[IIIgGeeksIII]

i can build this of lego midstorm but for less money and time lol

[orence69]

oh, melting! ~.~

[gSTA1992]

If i may ask what kind of welder was that it seems like a mig welder but what type excatly is it

[lob413]

@gSTA1992 It is a Campbell Hausfeld welder. MIG/Flux Core Wire Feed Welder

Item Number: WG206000AV. It worked really great. I would suggest learning on scrap metal with similar thickness to what you want to weld first though. Good luck.

[darexinfinity]

you had to make this from scratch?

[lob413]

@darexinfinity Yup.

[jaswandful]

hey will u pls send me the report of project , i really appreciate this project ,hoping for positive result

[jpm567]

AEROSMITH!!!! FTW! good song choice havnt heard that song in a long time :P and good job (:

[wilson1824]

See another video done for the same project that was completely remote controlled by searching Mechanical Engineering Walking Mechanism Project - Wolfgang Spider.

[deaftodd]

Fail!

[pratik1876]

hey, can u pls tell me hw much is the buget for this project.....is it around Rs.10,000-15,000.

[lob413]

@pratik1876 The frame was donated from another students past internship, the screwdriver that was used as a motor was donated from my past internship, and the various wire, nuts, and bolts were donated from the University's machine shop. The chain, sprockets, and threaded rods used for the drive train were the only parts we purchased. They only cost us about $30 USD or about 1400 र at today's exchange rate.

[DanielCMM]

WALL-EE!!!!!

[renmx]

hey lob.

can you tell me what is spec of ur motor used? this is small but powerful motor. Because i need it for my conveyor project design. This is my e mail add renmx12@yahoo.com. i hope u can reply to me. tnx a lot.

[lob413]

@renmx It is discontinued now but it was a Campbell Hausfeld Cordless Screwdriver. It was 160RPM. Do a Google search for Cordless Screwdriver and there will be several results that should work the same as what I used.

[Anshul701]

Hey lob this is really amazing, i need a favour, please send me the details of the dimensions of legs and intermediate connecting rods.I need them very urgently.It will be very helpful if you reply in any case as soon as possible.

My email id is anban555@gmail.com

[jaiprasad4]

wat's ur mail id.. i need to contact u for further information about ur project

[mechanicalromanceSN]

could you please send me same information you sent to deveshbabbar? here's my email : christinestaromana@yahoo.com . thank you :)

[therionthreethreenin]

u people are idiots...

[chevychase84]

Could you send me copy of this video? I am looking for ideas for my students kinematics course. What software did you use to do your design work. was it a special linkage software or just AutoCAD?

[lob413]

@chevychase84 I'm sorry, but I don't have the actual copy of the video I uploaded. We designed it using Solid Works. There was another program that we used to simulate the motor and gravity. It was a Kinematic program but I don't remember what it was called. It was outdated anyway. I'm sure you can find more up to date programs.

[cronosu2]

ohh thats cool.. in a few weeks I will star with this carrer..congratulations..

[MrRocrma]

This is really impressive and may have practical applications for developing exoskeletons. Good job !

[deveshbabbar]

hey lob can you please make it a bit faster................ i need that stuff urgently.... plese dont mind...

[lob413]

@deveshbabbar I replied to you via facebook. Good luck!

[deveshbabbar]

ok... thank you for this help.

[deveshbabbar]

hey..i am a student doing my B tech in mechanical engineering. i want to make this project. Can you kindly help me with whatever you can. it may include: the source of screwdriver motor. the material used. any details that you can give,. steps to construct or allign the links. kindly tell me from where to start with. i will be very grateful to you. kindly mail me the required information on my address.... devesh.babbar44@gmail.com 

[lob413]

@deveshbabbar Give me a few days and I will try to put together information for you for reference and email it to you. Please don't just copy the design, but use it as inspiration for your own design.

[goose2goose2]

Japanese students who are 14 yrs old build much more complex bots

ain't america great...the brightest minds we have in college, now

directly compete with asian pre-pubescent teens.

[lob413]

@goose2goose2 If I was supposed to build a robot, I would have built one and it would have been much more complex. That wasn't the requirement. We were supposed to build A LEG. We went above and beyond the requirements and built six legs, and added a motor. This wasn't a robotics class, it was a kinematics class. If we built a robot we would have FAILED because it wasn't the requirement.

[610blueeyes]

very good , its walking like big rebort

[cannibuzz83]

i'm at a community college, working on my core classes right now. won't get to touch a physics or engineering class for a year or more, until i am up to date with my math. is there anything i can do to occupy my time to keep myself motivated? what should i be getting into in my own time, while unable to take any classes relevant to my major? my question is more or less this...if i am without any experience in engineering thus far, is there anyway i can at least get a grasp on some foundation?

[lob413]

@cannibuzz83 In class, see if you can take some Computer Drafting or 3D CAD classes. Those aren't too hard but would give you a jump on other people. Outside of school, for M.E., I would play, tinker, build, and tear apart anything you can. I found that for my first job, everyone I was competing against had the same class experience but I had much more hands on experience which set me apart. If you have the time, build little projects like these and document them. They look great on resumes!

[BenjaminAKozlowski]

@cannibuzz83 I agree with them. Become proficient at solid modeling in CAD. You can develop proper geometries and test on screen before even making a component. Solidworks or Inventor are a good start...no need for ProE.

[slaverss]

wow...so great....id like to see more...it will be more great if it have a steer that can control it like a real robot...

[flarejet]

@lob413 from one Engineering student to another I agree. Alot of math, if only it was just trig.

[lob413]

@flarejet Lol.

[lob413]

It would be easier for you to do a google search about the requirements for Mechanical Engineering at a University near you than for me to list out all the classes I have taken. It took just over 5 years and there is a LOT of math involved. Much more than just trig.

[damion223]

im going to be a engineer after i get done with some things that go hand in hand with engineering. im right now doing machine tool tech and about to start my welding diaploma i was just wandering how yall go about doing ur classes, how long it will take and what classes do u have to take like math and such i have done machine tool math and it invovles trig and such i was just wandering? message me back please thx : )

[sadiqueshamvil49]

oh its nice project i ever seen

[vanepico]

Thats pretty awesome!

[moamenahmed]

Whats the RPM of this motor ?

[lob413]

@moamenahmed I'm not sure about the motor, but I think the whole screwdriver runs at roughly 100 RPM. Then the chain and sprockets gear it down by about 5:1 so the legs turn at roughly 20 RPM, if my memory serves me correctly.

[snake233]

schleeeeeeeecht

[xzharmayne03]

ugly.. at least you tried.

[PCDTSME]

@xzharmayne03 ya, thats what i think so to. i've made better things just as fun projects in a week or so, and this is suppose to be a final project? its cool, but come on...

[FireDepartment619]

Is Mechanical Engineering more in Mathematics? I'm slow in Mathematics :(

[lob413]

@FireDepartment619 Yes. Engineering relies heavily on math and also physics.

[Scerab]

That was pretty cool, did you make the gears yourself in that machine shop? I'm just curios because i will be going to college for mechanical engineering next year and i don't know how we would go about getting parts for projects. There is nothing about machining in the course description so i doubt i will be making them myself.

[lob413]

@Scerab The sprockets and chain were ordered through McMaster-Carr. It's a great resource for almost any mechanical need.

[Scerab]

@lob413 thanks, I'll keep that in mind. what is your course like? and what kind of things do you plan on doing with what you learn? Sorry for all the questions, i am just really excited to get started.

[lob413]

@Scerab This course was a few years ago but I liked it very much. I actually already work as a Design Engineer for an automotive supplier. I don't mind the questions as long as people don't ask me to give them all the details of my design. Sorry for the late reply.

[Scerab]

@lob413 that's OK, what kind of thing do you get to design? o, and what position did you start in out of college if you don't mind me asking.

[ankitshukla188]

i really liked it and i want to do it my self so could you help me by telling me the dimensions and the links analysis please give me inf as soon as possible.

[lob413]

@ankitshukla188 Please read the description in the video, "I'm sorry, but I will not share the details of this project beyond what you see in the video because that could be considered academic misconduct. Please don't ask me for the dimensions of the legs or the geometry of the mechanism. That information is what the project was graded on. If you would like details of the methods I used to assemble the project or my source for materials, I would be willing to help with that."

[ankitshukla188]

i really liked it and i want to do it my self so could you help me by telling me the dimensions and the links analysis please give me inf as soon as possible.

[ankitshukla188]

i really liked it and i want to do it my self so could you help me by telling me the dimensions and the links analysis and another arrangements so plese give information as soon as possiable

[ankitshukla188]

good video

[kokiruchi]

0:04 nerds

[MrZebry]

nice work lol

i really liked it and i want to do it my self so could you help me by telling me the dimensions and the links analysis

[UserIsAnFBIAgent]

Very Nice. Good Work.

Rated 5/5.

[randommagnum]

Dents in the table!  Too bad the legs weren't rounded at the end with some rubber coating on the edge...but what the heck.

[nujrailhok]

@markthreemillion... get ur ass up... shithead... how the fuck can u call "mech's" GAY...

mechanical RULZ......

the REAL men...

[leebahrija]

soooo cooooooool

[chandan6119]

could you send the design of the project

[markthreemillion]

mech eng is gay ... medical school would have been easier and more rewarding ..

[DW793]

Interesting, so people who have a passion to design and developed and love physics and science should drop that creativity and join medical school who pratcially denies almost 70% of students? No thanks.

[ysbshankar]

amazing

[dEaMoNiFiEr]

really amazing

[Aayush3004]

hat offs to u guys

[fatsotomuscles]

maybe they wanted something that walked, not rolled.

[ih8umor]

try a wheel next time

[hardriderx]

good work !!!

[mio68df]

thats cool

[water353600]

very cool project.

[ale03000]

Looks interesting, great work :)!!!

[isuranga123]

cool

[phillipbeynon]

A great deal of work just to build something with a clunky motion and no steering.

[cr1tterp0wer]

i think it was a lab project= limited time to create-

not bad though

[rbmdl]

AMAZING!!

[fesabililah]

thats so cool!

[BillBillnBillina]

thats pretty damn sweet

[CaliWarrior408]

COOL PROJECT

[kentoiful]

kool...

[fusionrock666]

amazing!

[TheMuslim100]

Looks good, but what's the use of this mechanism ?

[Jesus45U]

Cool thing .. heck, I think one could make one of those with LEGO too.

Gotta try that.

[reflector1000]

that was crazy!!

[legend1423]

that is excellent due can i hv more info abt it ??

[lob413]

Yup. The project was even voted best in class.
