The state space is populated with joints in the order that they are
defined in this file. The actuators also operate on joints.
State-Space (name/joint/parameter):
- cart slider position (m)
- pole hinge angle (rad)
- cart slider velocity (m/s)
- pole hinge angular velocity (rad/s)
Actuators (name/actuator/parameter):
- cart motor force x (N)
