Inspired from the DAGU wild thumper . I went down the road to make one myself .. a more powerful one .Respect to the creator OddBot. I am using 6 Pololu - 50:1 Metal Gearmotor 37Dx54L mm . The motors on the central panel are with encoders to keep track of the distance. The Project also includes a 5 DOF robotic arm also hand made. This is the progress .
The Alluminium chassis we hand moulded with a hammer :D
Next we worked on the suspension .. We used T-joint Pipes for holding the motors ..
We used these acrylic plastic circles to reduce the circumference for the metal rods to fit in.
The wheels are sadly made of plastic :( ..we used pig iron 2.5 inch shaft extenders to connect them to the motors.
Wheels ready to put in just like Oddbot taught us the suspension ..:D
Put in the electronics ,2 10-A H-bridges ... A Shield made on veroboard .. to connect everything to the Arduino Mega ADK
and some screw rods to hold the upper body and the arm at a distance and of course some paint . :D
And the Final look
More details and videos soon :)
The arduino code is attached , the file warMachine.zip .. Any suggestions or requests will be appreciated :)
