Introduction
Robotics has transformed industries by enabling automation, precision, and efficiency. However, many applications require robots to interact with dynamic and unpredictable environments. Impedance control emerges as a critical strategy to manage such interactions effectively. At MHTECHIN, we explore and implement impedance control techniques to enhance robotic performance, ensuring safety and adaptability. This article delves into the principles of impedance control and its applications.What is Impedance Control?
Impedance control is a control strategy that regulates the dynamic relationship between force and motion during robotic interactions with external environments. Instead of focusing solely on position or force, impedance control adjusts the robot’s mechanical impedance (stiffness, damping, and inertia) to achieve desired behavior.
Key Concepts:
- Mechanical Impedance: Defines how a system resists motion when subjected to force.
- Compliance Control: Adjusts the robot’s flexibility to interact safely with humans or fragile objects.
- Hybrid Force-Position Control: Combines force and position control for precise handling of tasks.
