Tunes Kp/Kd gains for a single joint at ~100 Hz using sinusoidal tracking or step-response, and prints error statistics.
FlagDescription
--l / --rArm side (required)
--joint JOINTshoulder_1, shoulder_2, shoulder_3, elbow, wrist_1, wrist_2, wrist_3 (required)
--kp FLOATProportional gain (required)
--kd FLOATDerivative gain (required)
--tffApply full feedforward (gravity + friction)
--mode {sine,step}sine = sinusoidal tracking (default); step = step response
--amp FLOATMotion amplitude in rad (default: auto safe value)
--freq FLOAT[sine] Frequency in Hz (default: 1.0)
--duration FLOAT[sine] Duration in seconds (default: 5.0)
--hold FLOAT[step] Hold time per phase in seconds (default: 2.0)
--rate FLOATCommand rate in Hz (default: 100.0)
