Summary
This study introduces a novel control method for biped robots to maintain static balance against unknown periodic external forces. The method learns to adapt and achieve balance without relying on ground reaction force feedback.
Area of Science:
- Robotics
- Control Theory
- Machine Learning
Background:
- Biped robots require robust balance control, especially when facing unpredictable external forces.
- Traditional methods often rely on ground reaction forces, which can be limiting in dynamic environments.
Purpose of the Study:
- To develop a control method for biped static balance under unknown periodic external forces.
- To enable adaptive balance control in uncertain environments through a learning process.
Main Methods:
- A learning process is employed to clarify environmental uncertainties and acquire a torque pattern for balancing motion.
- The control method operates in a feedforward manner, adapting to periodic external forces.
Main Results:
- The proposed method successfully achieves static balance for biped robots.
- Balance is maintained adaptively without requiring real-time feedback from ground reaction forces.
Conclusions:
- The feedforward control strategy effectively manages unknown periodic external forces.
- This approach enhances the autonomy and adaptability of biped robots in complex environments.
