What sensors does assistive robots how and does assistive robots use these sensors?

Assistive robots typically use a variety of sensors, including cameras, ultrasonic sensors, lidar, and touch sensors. These sensors enable the robots to perceive their environment, detect obstacles, and recognize objects or people. By integrating data from these sensors, assistive robots can navigate safely, interact with users, and perform tasks such as fetching items or providing mobility assistance. This sensory feedback is crucial for enhancing the robot's functionality and effectiveness in assisting users.
