20170266806 · 2017-09-21 · ·

A modular robotic snake-arm assembly is described which is animated principally by an articulated drive shaft that threads the length of the snake-arm. The articulated drive shaft is driven by a motor in the fixed base. One or more clutch mechanisms in each segment couple with the articulated drive shaft so as to cause all snake arms further from the base to reorient in either one or two angles, in either direction. Snake-arm segments can be coupled end-to-end to form a robotic snake arm of great length.
