FAQ

1. What is the main purpose of a dexterous hand kinematics test?

Kinematic testing evaluates how accurately a robotic hand performs intended movements. It measures joint angles, trajectories, positioning accuracy, speed, and gesture execution to verify overall motion performance.

2. Why is repeatability testing important for humanoid robot hands?

A robot hand must consistently return to the same position when performing repetitive tasks. Repeatability testing identifies positioning drift, mechanical wear, and control system inconsistencies that could affect manipulation accuracy.

3. How does trajectory measurement improve robot hand development?

Trajectory analysis reveals the actual motion path followed by the hand or fingers during operation. Engineers can compare planned and actual trajectories to optimize control algorithms and improve movement precision.

4. What role does the 1 kHz sampling rate play in testing?

The high-speed acquisition rate captures fast finger movements and transient motion events that lower sampling systems may miss. This enables more accurate dynamic performance evaluation and control system tuning.

5. Can the system be used for robotic hand calibration?

Yes. The platform supports kinematic calibration by measuring actual joint positions, movement ranges, and motion errors. Calibration helps improve overall positioning accuracy and control performance.

6. What types of robot hands can be tested?

The system is suitable for:

• Humanoid robot hands

• Multi-finger dexterous hands
