Abstract
There are many research approaches to develop intelligent robot. However most of them could not be applied to real tasks. We think it is important to develop a new hardware design concept which includes moduled robot elements and system interfacing flexibility through verious robot developments. Through this concept moduled robot elements which have new open interfaces to be useful for many kind of users were developed. These elements have hierarchical 5 level hardware modules; Mechanism, Servo, I/O, Network, Computer interface. By using this result, we could develop some robot systems, e. g. 7-Axis Manipulator, Under Water Maintenance Robot with Double Arms and Oil-Tank Bottom-Plate Blast Robot, and require some evidences in order to develop robots rapidly. We think our Open System causes many Intelligent Robots to be applied. Because most of intelligent robot researcher can work in own field without robot hardware developments which require much research part.
