Joint angle sensing

Definition

Joint angle sensing refers to the ability to measure the angles formed at joints in a robotic or biological system, enabling accurate monitoring of limb positioning and movement. This process is crucial for both tactile sensing and proprioception, as it helps the system understand its spatial orientation and how its parts are moving in relation to one another. By providing feedback on joint configurations, joint angle sensing plays a vital role in enabling coordinated motion and precise control of robotic systems or biological limbs.
