Plain English summary

The research presents a new control strategy for actuators in soft robotics that combines shape memory alloys (SMAs) and shape memory polymers (SMPs). This integration allows for advanced shape adaptation and stiffness variations, which are crucial for effective robotic movement and functionality. A multi-target thermal sensing method (MTTSM) is introduced to enable precise control over the programmed deformations and stiffness changes. Additionally, a co-training-based monitoring system is developed to dynamically monitor the deformed states of the actuators, enhancing their operational capabilities in soft robotics applications.

Why this matters

This research addresses the challenges of achieving complex deformations and effective control in soft robotics, which is essential for creating more adaptable and responsive robotic systems. By improving the integration of shape memory materials, the findings could lead to advancements in robotic applications, making them more versatile and efficient in various tasks.

Key findings

  • Proposed an integrated control strategy for SMA-SMP based programmable morphing structures.
  • Developed a multi-target thermal sensing method for precise control of deformations.
  • Enabled coordinated actuation between SMA springs and SMP structures.
  • Introduced a co-training-based monitoring system for dynamic state monitoring.
  • Facilitated the use of multisensor fusion for position estimation in flexible bodies.

What's new

The integration of MTTSM with a co-training monitoring system for controlling multiple shape memory materials in soft robotics is a new approach.

Limitations

The abstract does not provide details on experimental validation or real-world applications of the proposed system.

Commercial context
