Here’s a cool 3D printed robotics project shared with us by Miguel Ángel de Frutos Carro:
Shows the manufacturing and operation via bluetooth of a mini caterpillar dozer 3D-printed based in the Prof. Brian Evans‘ previous work in Thingiverse.
BoboBOT can be controlled via Bluetooth for remote control or running autonomous way.
Push objects, save obstacles,explore hard terrains or take part in a mini sumo’s fight! Modify the printed parts,add new sensors and update the original model to improve its capabilities.
Part list: 3D parts, caterpillar 22-tooth silicone tracks, microcontroller (Arduino or similar), Pololu micrometal gearmotor (50:1 e.g.), motor driver, battery pack and optionally, wireless device (such as bluetooth or ZigBee).
I printed a first version in pink ABS, but it wasn’t hard enough. So I modified (god bless open hardware philosophy) the original bwevans files to improve its resistance and printing again in PLA. The final result: a stronger and easy to print main body.
