Q8bot is a miniature quadruped robot with the size and weight comparable to a modern smartphone. This robot is capable of dynamic movements like walking, trotting, bounding, jumping, and more. It also has NO WIRES AND CABLES – everything is directly plugged into the center PCB, greatly reducing complexity, weight, and cost. The current BOM, without optimization, starts below $300.
