The sensors that an engineer puts on a robot are entirely dependent upon the functions that the engineer perceives that the the robot will be called upon to perform. Some, but not all, of the sensors may be: proximity sensors, pressure sensors, light sensors, magnetic sensors, a camera, temperature sensors, accelerometer, speed sensor... The question isn't, "what sensors does a robot have", but rather, "what sensors does the engineer think that the robot should have?"
He has groud and visual sensors
Alot of them use a sonar-like sensors that emit soundwaves to help them "see".
not all do, but most do
Robot toys can be purchased at Toys R Us, Walmart, and Target. These are the simpler versions for younger children. For a more complex toy, Radio Shack offers a couple different styles of tin can robot kits. These are for turning a simple tin can into a operational robot.
Yes, of course. Sensors are necessary to check own status and/or of any object (like human target). Without sensors any robot is not able to search, find, indentify or even to move in difficult area. Sensors are important to receive feedback for the human, who is steering a robot. If robot is at automatic drive (no human is steering - only on software running) sensors are also very important to the robot to get any information about the outside, the surrounding of it.
Robot sensors detect different things and send different amounts of electricity to the Robot's controller board to tell their findings. Then the controller board uses these different amounts of electricity to interact with its surroundings. Example: Lets say you have a robot that is made to follow light. Lets say your robot has 3 light sensors. One in the front of your robot one on the right and one on the left side. The sensors will detect how much light is on the front, right, and left sides and send this data to the controller board. Then the controller board uses this data to tell the robot with direction to go.
You can buy robot toys for young children at toy stores such as Toys "R" Us and Laugh and Learn both at their physical locations as well as online. You can also buy these toys at big box retailers such as Walmart and Target.
Using sensors it was programmed to use.
It has gears, a mother board or controller, sensors, and a battery.
