Basic Concepts of ABB IRB 120 DH Parameters: The Building Blocks of Robotic Motion
DH parameters (Denavit-Hartenberg parameters) define the relative position and orientation of adjacent links in a robotic arm. They are crucial for understanding how the robot moves, allowing you to accurately plan trajectories and avoid collisions. By understanding these parameters, you can:
- Control the robot's movement precisely: DH parameters enable you to mathematically define the position and orientation of each joint, ensuring smooth and accurate motion.
- Avoid collisions with obstacles: Precise knowledge of the robot's configuration allows you to predict its movements and prevent it from colliding with nearby objects.
- Optimize robot performance: By fine-tuning DH parameters, you can improve the robot's efficiency and performance by minimizing energy consumption and maximizing speed.
