Inventor James Bruton Builds a Working Mobius Strip Tank with a Twistable Tread System

James Bruton Mobius Strip Tank
Inventor James Bruton built a working Mobius strip tank for his latest project, and for those unfamiliar with the term, it basically refers to a one-sided surface with no boundaries that looks like an infinite loop. In tank form, this meant creating a twistable tread system with each link being able to rotate 18°, and despite how it looks, the system functions like any other.



After some planning, Bruton settled on 3D printing each piece separately, thus if a replacement is needed, it can be easily done without having to reprint the entire thing. Other parts used include an Arduino Mega development board, a pair of 24V gear motors to drive each tread independently, BTS7960 DC motor drivers, and an RC radio receiver.
