Arduino Robotic Arm

This has been what I have been working on for a while. I took this to the international science fair in Pittsburgh where I took second in the world in engineering. I just finished my Sophomore year in high school and am already working on the next prototype.

This is extremely impressive. I'm building my own arm right now, a much smaller version, roughly 2 feet from shoulder to tip, with 7 DOFS. 2 in the shoulder, one in the elbow, two in the wrist, and one to open and close the gripper. I'm building it to assist in soldering, controlled by servos on a Teensy board. Teensys are much more advantageous I believe, more PWM ports,and can run Arduino libraries. Look into it, if you haven't already. Anyways, I only have the hand done, watch?v=Cje4T2xRGfg

I love the teensy's! i have 3 right now and they are great! I wish they had a regulator on them though like the arduino. Great project though! 3d printers are they best!

can i have a copy of program of this robotic arm???

[Easton LaChappelle]

Is there a certain part you want? It's pretty messy.

How many dc servos did you control on each arduino? What was the program like?

[Easton LaChappelle]

I only had one arduino board. The other boards just had the logo on them (some chinese thing). I controlled 3 dc servos from it though. The program was pretty simple, just some math and some actions to the motor.

....He did.....

If anyone was wondering ShapeLock was the meltable plastic that he used (I think).

you should make it be able to shake a users hand

For anyone interested in duplicating this project. 1. Go small first. 2. Use lightweight frames by Lynxmotion to construct the prototype. 3. Use hobby servos. These will fit together with the Lynxmotion hardware. 4. If you really want to scale your project to this size, Stepper motors or DC motor with built-in encoder is the best bet. 5. Use inverse and forward kinematics to control complicated motion of the arm. This are really well known, just google them.

Wonderful work on this and congrats on meeting the president! Those motors must have been such a nightmare to implement. I'm glad to see you got to hardware quickly and worked through all those issues. I wish you the very best in your upcoming projects! Keep your mentality for getting to hardware quickly. This is the fastest way to learn if your designs make any sense.

[Ron Hebshie]

Congrats on meeting the President and for your amazing work. So cool to hear stories that celebrate science, smarts and the amazing members of the next generation of great thinkers. BRAVO!

Pretty cool and quite impressive.

What did you use as a power source for all those stepper motors? Each one must require around an amp and you had 4(?) plus the servos on top, so it had to be something fairly beefy (if my understanding of the power requirements is correct that is!). Did you connect it to the mains electricity or something else?

look for some Fab Lab in your city: (youtube dont allow to put url here, so you should search by yourself for Fab Lab MIT and you will find the operating Fab Labs)

There you can use a 3D printer and other tools you might want.

Make it mimic your movements

[Danilo Alvarenga]

Great work man! I'd like to see how exactly you implemented the potentiometer to the DC Motors. Can you give me more details on that?
