## Summary

The article derives the dynamics of a wheel-legged inverted pendulum and explains why the wheels must accelerate in the direction of the fall for a quadruped robot to stand on only its two rear wheels. It also analyzes the privileged-information design of an asymmetric actor-critic and tests the limits of four policies through cross-physics-engine experiments.
