Breakthrough in Robotics: Czech Technical University Develops Innovative Mechatronic Design
Researchers at Czech Technical University have successfully designed and validated a minimal configuration brachiation robot with a single rigid rod and gripper mechanisms. Funded by the Agency of the Czech Technical University, the European Union's Robotics and Advanced Industrial Production project, and the Grant Agency of the Czech Republic, the team's innovative design has achieved remarkable results in both simulations and experimental validation. The robot's mechatronic control design, which includes a nonlinear model and optimal control strategies, has been implemented on a low-cost STM32-based control system, demonstrating a significant advancement in robotics research.
Key Takeaways:
- The robot consists of a single rigid rod with gripper mechanisms attached to both ends, allowing it to swing or rotate.
- The grippers are used to hang the robot on a horizontal bar, which is imposed by repositioning the robot's center of mass using a crank-slide mechanism.
- A nonlinear model and optimal control strategy were proposed for repositioning the center of mass in a bang-bang manner.
- Utilizing input-output linearization, a continuous control strategy was proposed to take into account the limited torque of the crank-slide mechanism and its geometry.
- The research team implemented the continuous control strategy within a low-cost STM32-based control system and experimentally validated the swing and rotation stages of the brachiation motion.
- The innovative design has significant implications for robotics research and development.
- Authors including Tomas Vyhlidal, Juraj Lieskovsky, Jaroslav Busek, Hijiri Akahane, Aoto Osawa, and Ikuo Mizuuchi contributed to the research.
