A lot of researchers use robots to help them in their work. These robots are basically quite simple and machine-like in appearance, however, the software that is used to program their functions can be very sophisticated. They are able to move around using different navigation techniques. Some of these machines use vision-based systems.
Complexity of Robotics Research
These require more computational resources, and the computation is done through a digital signal processor which is embedded within the robots’ cameras. Other robots use laser-based systems with range-finding lasers that are accurate up to a centimetre. The vision-based systems are frequently used for consumer robots because they tend to be less expensive. Commercial and industrial robots use the laser-based systems because they require more precision in their work.
