Review Questions

• How does neural network-based control enhance the adaptability of soft robotic systems?
  • Neural network-based control enhances the adaptability of soft robotic systems by allowing them to process sensor data in real-time and adjust their movements accordingly. This responsiveness enables soft robots to navigate complex environments, respond to unexpected obstacles, and optimize their performance based on learned experiences. The ability to learn from feedback helps these robots continuously improve their actions, making them more effective at completing tasks in dynamic settings.
• In what ways does reinforcement learning complement neural network-based control in soft robotics?
  • Reinforcement learning complements neural network-based control by providing a framework for training these networks through trial and error. As a soft robot interacts with its environment, it receives feedback in the form of rewards or penalties based on its actions. This feedback is used to adjust the neural network's parameters, allowing it to learn which behaviors are most effective for achieving desired outcomes. This synergy leads to robust control strategies that adapt over time as the robot encounters new challenges.
