CRISP introduces a set of compliant ROS2 controllers for robotic manipulators, offering a robot-agnostic framework that enables robust deployment of learning-based manipulation policies and intuitive teleoperation. The system provides real-time Cartesian and joint-space control, integrating features like force feedback to facilitate interaction with physical hardware.
Key insights
- Compliant, torque-based control is critical for enabling robots to safely and accurately execute discontinuous commands from learning policies and for performing contact-rich manipulation tasks.
- A robot-agnostic control architecture, built on `ros2_control` and `pinocchio`, facilitates broad applicability across diverse manipulators, reducing development effort and promoting standardization.
- Integrating advanced features like error clipping, dynamic parameter configuration, and force-torque feedback significantly enhances control precision, safety, and the efficacy of human-in-the-loop teleoperation.
