Does IsaacGymEnvs support unitree aliengo training

[tinnerhrhe]

The legged_gym codebase failed to train unitree aliengo robot. The robot even can not stand up given fixed correct command. However, if I replace the 4 {RR,RL,FR,FL} 'continuous' thigh joints to 'revolute' and add corresponding limits, robot can be trained well. What's the problem, does IsaacGymEnvs support unitree aliengo training?

As per the current documentation for Isaac Gym(1.0preview4),

"Fixed, revolute, and prismatic joints are well-tested and fully supported."

Changing the joint type from continuous to revolute with limits is the right fix.
