Sensor-based robot systems

Sensor based robot control systems can overcome many of the difficulties of uncertain models and unknown environments which limit the domain of application of current robots used without external sensory feedback. Among various sensors, vision is expected to play a very important role in control of intelligent robot. In this paper robot control systems with vision are firstly discussed. Then a control scheme for a robotic manipulator system is described, which uses visual information to position and orientate the end-effector. Recently there has been increasing interest in upgrading robot intelligence by using multiple sensors. Therefore this paper also focuses on the multiple sensor system, especially sensor integration or fusion schemes. A navigation method for a mobile robot based on cooperation of vision and range sensors is described
