3D Printed 4×4 Rover

I had a kit of 4 DC motors (3-6V) with wheels in my toolbox for years. The cheap yellow set (you can find it for about 5USD, shipping included). My plan was to put these to use and it was a perfect weekend project opportunity with my daughters.


I also had some interesting ideas to build a 4×4 rover where each wheel has its own motor, but also a pivotable fixing system that allows each wheel to elevate independently in order to bypass any obstacles. Something like a leg holding a wheel and the leg then being fixed to the main rover body via some elastic pivot for improved mobility. The design part was quick and rewarding . Then first was to measure the DC motor size and holes do a quick print for test and correct any issues.
