Standardized and Radiation-Tolerant Motor Controllers for Space Robotics

The Zeta motor controller is a modular, radiation-tolerant motor control solution designed to meet the demanding requirements of space robotics, satellite actuation, and deep-space mechanisms. The objective of this project is to develop firmware that ensures full compliance with the DS402 standard, enabling seamless integration with existing robotic platforms and expanding support for multiple motor types, including brushed DC, brushless DC, and stepper motors. The firmware development will focus on implementing position, velocity, and torque control modes while ensuring high-precision feedback and robust fault tolerance. The CAN-based communication protocol will be optimized for reliable, low-latency data exchange in space environments. Additionally, adaptive auto-tuning algorithms will be incorporated to streamline motor parameter configuration, reducing the need for manual adjustments and improving performance across various operational conditions. To validate the firmware, software-in-the-loop (SIL) and hardware-in-the-loop (HIL) testing will be conducted, ensuring compliance with DS402 and compatibility with multiple motor configurations. A graphical user interface (GUI) will be developed to provide intuitive control and real-time monitoring of motor parameters, enhancing usability for space and terrestrial applications. By leveraging Novium’s dual-path development strategy, the firmware will be tested on terrestrial controllers before transitioning to a radiation-hardened version for spaceflight qualification. The resulting firmware will provide a cost-effective, adaptable, and high-reliability motor control solution for NASA missions and commercial space applications.
