Q8bot is a palm-sized quadruped robot. It weighs around 221g and is capable of dynamic movements like jumping and various gaits. It also has no wires and cables - everything is directly plugged into the center PCB, greatly reducing complexity, weight, and cost. The latest version adds a Qwiic/Stemma QT connector to the robot, which will allow easy integration of additional hardware (IMU, ToF sensors, screens) if desired.

The project is fully open source from software to hardware, and building your own Q8bot is very simple: Assemble the PCB, solder the custom battery frames, install the actuators, and attach the legs. No wires or cables needed. Many of the steps can be done by companies such as PCBWay, including assembling the PCB and 3D-printing (Nylon or PLA) all of the mechanical parts.

The current BOM, without optimization, ranges from under $300 to $400 depending on level of outsourcing.
