RedShow SYSID-A-RMA Sim-to-Real Project
A wheel-legged robot project that combined system identification with an A-RMA-style adaptation pipeline to reduce the simulation-to-reality gap.
01
What I Did
- Built a reinforcement-learning workflow for a six-motor wheel-legged robot with position-controlled legs and velocity-controlled wheels.
- Combined identified physical parameters with an adaptation module instead of relying only on broad domain randomization.
- Integrated encoder and IMU feedback at 200 Hz with a 50 Hz policy and a 30 Hz adaptation module.
- Deployed through OpenCR, RS-485 leg communication, and CAN wheel communication, and demonstrated physical obstacle traversal.
- Presented the team prototype with Hyeokjo Kwon and Seongwoo Bae.
Reported results are based on the project presentation and physical prototype demonstration; a larger quantitative evaluation was not conducted.
