From the project

The Github Repository for MEng project 2025/26

Author: Charlie Date: May 2026 Project: MEng PROJ500 — Plymouth Humanoid Robot

This folder contains all hardware and firmware deliverables produced during the 2025–26 academic year. It is structured into three top-level areas:

The robot's electronic architecture is split across two custom boards:

The PDU and RCU communicate over a dedicated management CAN bus (250 kbps). The RCU talks to the Thor AI computer (Jetson/PC) over UDP/Ethernet. Motors are driven by the RCU over two 1 Mbps CAN buses using the RobStride RS04 private protocol.
