Bipedal RL Walking Robot

Team: Spencer Gardner and Zac Maughan

Project

The Problem: Traditional bipedal control is manually intensive, while physical hardware testing is slow, expensive, and prone to damage.

The Solution: This project utilizes a Sim-to-Real Reinforcement Learning pipeline to:

  • Accelerate Development: Rapidly train walking policies using NVIDIA's IsaacLab simulator.
  • Reduce Costs: Iterate on locomotion logic in a risk-free virtual environment before hardware deployment.
  • Optimize Performance: Generate robust control policies that adapt to physical hardware constraints.
