FAQ

1. Why is balance testing important for humanoid robots?

Humanoid robots operate in dynamic environments where unexpected disturbances are unavoidable. Balance testing verifies whether the robot can maintain stability and recover from external forces without falling.

2. What is the purpose of push recovery testing?

Push recovery testing evaluates how effectively a robot reacts after being disturbed. It measures whether the robot can use corrective movements such as stepping, ankle adjustment, or body posture compensation to regain balance.

3. Why use a pendulum impact system instead of manual pushing?

A pendulum provides highly repeatable and quantifiable impact conditions. This ensures consistent testing results and allows accurate comparison between different robot designs or control algorithms.

4. What data is collected during testing?

The system records:

• Impact force

• Acceleration

• Pendulum position

• Disturbance intensity

• Recovery behavior

• Stability performance

These measurements help engineers analyze robot response and optimize control strategies.

5. Can the impact strength be adjusted?

Yes. Impact intensity can be modified by adjusting:

• Pendulum mass (5 kg, 10 kg, or 15 kg)

• Pendulum length

• Release angle

• Impact location

This enables simulation of various real-world disturbance scenarios.

6. How does this system support humanoid robot development?

The platform provides objective and repeatable stability data that helps engineers:

• Improve balance algorithms
