This is the Q8botOne: a palm-sized quadrupedal robot that doesn’t use wires or cables. This open source robot has parallel-linkage legs. It can jump, trot, and walk. It has a customizable hardware and firmware. It is powered by an ESP32-C3-MINI-N4 microcontroller and relies on 8 x DYNAMIXEL XL-series programmable smart actuators. You will be able to add Adafruit, SparkFun and other sensors thanks to its Qwiic-compatible connectors.
Q8botOne’s mechanical design was developed in Onshape. It has an UART interface for Raspberry Pi and other co-processors. More information is available here.
