Q-Octo uses a pair of CyberGear MicroMotors, which provide not only high torque and speed but also feedback such as current amp draw and position. To power the motors, 4 Parkside X20V drill batteries are used, providing 6-hour continuous runtime paired with robust and safe recharging.

Q-Octo is controlled via a Raspberry Pi Pico with the display and web server managed via a Raspberry Pi Pico W. The main pico communicates with the radio controller to receive control commands however, navigation via a separate onboard computer or via a flight controller is planned.

To build a Q-Octo, both a 3D printer and a laser cutter are required. It is sufficient to manufacture all 3D printed parts out of Esun PLA+, providing excellent durability. All laser-cut parts (*except the front and rear battery cover) can be cut from 6mm thick plyboard, which provides adequate rigidity and durability, assuming it is coated in outdoor paint.

Q-Octo was originally designed for ELEC6212: Biologically Inspired Robotics, a fourth-year module at the University of Southampton. Q-Octo was inspired by Q-Whex.
