Force Sensors

Definition

Force sensors are devices that measure the amount of force applied to them, providing critical feedback in robotic systems. They play an essential role in helping robots understand their interactions with the environment by detecting changes in force and pressure, which can be crucial for tasks such as manipulation and navigation. These sensors can be used to enhance proprioceptive awareness in robots, ensuring precise movements and safe operation when engaging with objects or humans.
