Quad Rover - version 2

thingiverse

Update: 22/12/17 version 2 released, slightly longer core and symmetrical wheel hubs. This is my Quad Rover base. It's designed as a platform for a robotic rover to utilize 25mm gear motors efficiently. It can be either remote controlled or fitted with a Raspberry Pi for remote Wi-Fi or autonomous operation. Also provided is a drill guide to drill out the pipe precisely. The motor tubes are constructed using PVC drainpipe, but if you have the inclination, you could print these out as well. You need to print four of the bumpers, which allow the bolts to mount and clamp securely against the tubing. Four-millimeter bolts are used to connect the front and back to the central core, while RC 1/10 wheels with 12mm hex adaptors are used for the motors efficiently. A complete rolling chassis with motors, wheels, and mounting bolts only costs around £50 in total. For the RC version, two RC ESCs, a mixer, and a battery should only cost about another £20. Then it's just the cost of a remote control and transmitter to get started. For the Pi Version, a quad motor shield like the MotoZero is recommended, which only costs £10 on top of a Raspberry Pi Zero Wi-Fi model. Additionally, you'll need a suitable battery and/or voltage regulator for about £3.
