MR6 - Mini Prototyping Tank Robot

thingiverse

This little tank is designed to enable my students to prototype their robotic ideas quickly and efficiently. It boasts several significant improvements over my previous versions of tracked robots. Utilizing 22mm skateboard bearings, improved ground clearance and greater track flexibility, this little bot can move confidently across a wide range of terrain with ease. It is engineered to be printed on a printer that is at least 120mm in size, although if you sacrifice the top shelf, you can print it in an Up! Mini. There are several different versions of this tank set to come out, with this first one designed specifically for prototyping in the classroom. It runs off a Tamiya 70097 Twin-Motor Gearbox Kit, but the rest of the electronics are up to you. In the video linked below, it is running with a Raspberry Pi Zero W and some Pololu motor drivers and power converters. https://www.youtube.com/watch?v=VD7uiKfXYNM PLEASE READ THE PRINT AND ASSEMBLY GUIDE CAREFULLY BEFORE PRINTING (This is the PDF in the "Thing Files") Please note - I cannot share with you the source CAD files.
