Survivor Bot 08M (PICAXE Tank Based Robot)

I give you "Survivor Bot 08M"... if your wondering about the name, well my sister (a full grown adult) picked the robot up and thew it across the room, smashing it on hard tiles. So you could say its had a bit of a rough development / early life :)

This robot is as simple as they come, you don't even really need to know much about electronics at all - no special circuits, everything is connected to the picaxe starter kit/board... These are the components that you need:

•1 x PICAXE 08M Starter Kit
•1 x SRF05 Ultrasonic Range Finder (can only be connected to an ADC pinout on Picaxe 08m)
•2 x Continuous Rotation Servo Motors
•1 x Standard Servo Motor
•1 x Tamiya Tank Tred and Wheel Set
•Jumper pins, wires, prototype board, wood and screws
•Some patience :)

Ideally the servo's should be powered by their own power source, however I didn't have the components lying around the house to make one. I also manage to stop the continuous rotation servo's by telling the pins to go low (e.g. low 2,4). This means that the head can turn and get accurate distance measurements. After that I set the pins high (e.g. high 2,4).

Most of my time was spent constucting the robot base, design, cutting, drilling, modifying the tank wheels, mounting of the servo's etc. The original design used a PBT plastic case/enclosure, however these plastic boxes are not "straight" they are all slightly trapezoid (why aren't boxes square anymore!?!?!?).

is there one i can buy?

[dizzeh000]

@alarmdemon Hmmm would be nice if there was a complete kit.... now you have me thinking.... lol :) Unfortunately at the moment though the answer is no :( if you check out the lets make robots website for this robot you could get a general list of parts... I can also email you a complete list of parts too!

Wow, I can't believe this little robot has had over 10,479 views!!! Thank you all for stopping by and checking it out - this has inspired me to create a bigger, better V2 Robot!!!

how much did you pay for the micro-controller? (PICAXE 08M Starter Kit)

[dizzeh000]

@sammyman60 - Hi Sammy, Robot Gear or Microzed sell the kits, but I can't seem to find the one I purchased... it also included the USB to Serial programming cable, I think it origianlly cost me about $50 AUD?!?!

Make Survivor Bot v2 with an edge sensor so it doesn't meet the tiles again :-p

[dizzeh000]

@GraemeC4 - its a good idea, however the 08M has very few IO's, even with this robot, the serial programming IO is used :( Would need to go the next PICAXE module up to introduce that feature! Thanks for the suggestion!

Wau great!

[nickezdenez]

what was the code that you used



[cosmonaves]

Very good!!! 

[sammyman60]

Cause this video actually inspired me to get back into this stuff, used to love doing things like this (in school though)

[sammyman60]

Thanks for the reply, I actually did alot of research for a good low budget kit and found one, it comes with everything needed, cept for the actual robot parts (wheels, chassis) I'm waiting for the package to come, once its here and I'm done making my minibot :D ill post up a video and link it to yours as an insperation (horrible spelling) to my robot
