Overview
A palm-sized quadruped with open hardware from ZeroWire Robotics, a Cupertino, California startup run by Yufeng Wu. It grew out of his open-source Q8bot from 2024, which he later published as research at UCLA's RoMeLa lab. The robot has zero wires, meaning every part plugs straight into one central circuit board that doubles as the chassis. Eight ROBOTIS DYNAMIXEL XL330 smart servos drive the parallel-linkage legs and report position, current and temperature over a shared serial bus. An ESP32-C3 runs the robot, and two 14500 Li-ion cells power it. The body measures 120 × 70 × 70 mm and weighs 250 g.
A matching ESP32-C3 controller drives it out of the box, with a joystick, several gaits and preset moves such as jumps and dances. Plugged into a computer, the controller becomes a wireless dongle for a desktop app, an Xbox gamepad or a Python API. There are no built-in sensors, though a Qwiic port and a powered UART accept an IMU, a camera or a small co-processor. It is a sensor-free alternative to Petoi Bittle, aimed at gait experiments, teaching and tinkering. The $199 kit plus eight servos from ROBOTIS comes to about $420, so the $599 assembled robot costs roughly $180 more (estimate). Orders placed during the campaign ship in March 2027.

Price and shipping
The $199 kit comes without its eight DYNAMIXEL XL330-M077-T servos, which ROBOTIS US sells at $27.49 each ($219.92 for eight). The fully assembled robot is $599. Both include free worldwide shipping. No later retail price has been announced. Crowd Supply campaign page and ROBOTIS US store, checked October 2026.
Shipping: Crowd Supply delivery est. Mar 2027. Live on Crowd Supply until November 19, 2026, at $5,580 of a $10,000 goal with 20 backers on October 25. Crowd Supply says orders placed now ship March 24, 2027, with delivery handled by Mouser Electronics. Elecrow makes the boards and printed parts, and final assembly is in California. Crowd Supply ↗
