![]() The next step in autonomous behavior is to actually perform a physical task. Some robotic lawn mowers will adapt their programming by detecting the speed in which grass grows as needed to maintain a perfectly cut lawn, and some vacuum cleaning robots have dirt detectors that sense how much dirt is being picked up and use this information to tell them to stay in one area longer. Common exteroceptive sensors include the electromagnetic spectrum, sound, touch, chemical (smell, odor), temperature, range to various objects, and altitude.The autonomous robot can recognize sensor failures and minimize the impact on the performance caused by failures. Autonomous robots must have a range of environmental sensors to perform their task and stay out of trouble. Sensing the environment Įxteroception is sensing things about the environment. Autonomous robots monitor and respond to proprioceptive sensors without human intervention to keep themselves safe and operating properly. The display is for user information only. Robot GUI display showing battery voltage and other proprioceptive data in lower right-hand corner. Common proprioceptive sensors include thermal, optical, and haptic sensing, as well as the Hall effect (electric). Increased proprioception will be required for robots to work autonomously near people and in harsh environments. Another common proprioceptive sensor is for heat monitoring. In the battery charging example, the robot can tell proprioceptively that its batteries are low and it then seeks the charger. Self-maintenance is based on " proprioception", or sensing one's own internal status. Many of the battery-powered robots on the market today can find and connect to a charging station, and some toys like Sony's Aibo are capable of self-docking to charge their batteries. The first requirement for complete physical autonomy is the ability for a robot to take care of itself.
