A computational framework employs Meta Reinforcement Learning (Meta-RL) to optimize the design of legged robots by concurrently evaluating morphology with near-optimal, adaptive locomotion policies. This approach generates robust designs tailored to specific objectives and terrains, achieving substantial computational efficiency over traditional methods.
Key insights
- Meta-learning successfully produces a general locomotion policy that can adapt to diverse robot designs, achieving performance comparable to specialized policies trained from scratch for individual designs.
- Optimal robot morphology is highly sensitive to both the performance objectives and environmental conditions, showing distinct designs for efficiency on flat ground versus navigation on rough terrain.
- Dynamically weighting performance-based costs against efficiency costs is critical for finding practical designs that can successfully perform a task while also being efficient.
