The jerk penalty penalizes acceleration changes—this is what makes motion look "robotic" vs "alive." Human and animal motion minimizes jerk naturally.

Tuning Tips

  • Start with -0.1 and observe the motion
  • If motion is still jerky → increase to -0.2 or -0.3
  • If the robot becomes too "sluggish" or struggles to respond → decrease to -0.05

action_jerk=-0.1, # smoothness penalty for character-like motion
