Summary

This is the TugBot that we built in Shenzhen to see how much power we could put through a Smartibot circuit board. It takes 4 x 545 gear motors and when we printed it using E-Sun filament on an Ender 3 could comfortably hold (and move) a person standing on top of it. With some additional weight on it's back it can also comfortably pull a person of up to 90kg on a trolley.
