In this paper, a scheme for a haptic communication system is proposed by using an FPGA (Field Programmable Gate Array) and real-time network framework, RTnet. In the haptic communication system, the FPGA is used as a motion control processor, and the Linux-based real-time network framework is applied to the communication line between a master and a slave robot. The FPGA can execute control calculations...
In this paper, data compression and decompression method for real-world haptics using discrete cosine transform (DCT) is proposed and applied to a motion copy system. Haptics recently has attracted much interests and been and studied by many researchers. The technology of real-world haptics based on bilateral control systems is expected to apply teleoperation for precise task, education system for...
In order to cope with many problems of everyday activities which requires robots to accomplish complex yet routine tasks in changing environments, this study focuses on universality and proposes seven principles of universal design with robots. These principles are used to design a robot management system that manages and controls information-structured environment with robots, ambient intelligent...
FPGA has been focused on as a controller of robot systems. Haptic robot system based on bilateral control system is one of the significant applications using the FPGA. In this paper, the bilateral control system including mode transformation is implemented on the FPGA. The bilateral control system is based on acceleration control system. The mode transformation is a transformation between robot mode...
A new method of shape modeling for robotic applications is proposed. We utilize visual ID-tags to acquire local tangent planes of objects, and generate approximate polyhedral models of the environment. We developed an optimization algorithm for estimating tag configurations and a method of forming polyhedral models of objects. Our approach enables easy modeling using a single camera without pose information...
In the field of motion control, robustness is an important issue to accomplish desired motion of robots. To achieve robust motion control, acceleration control has been studied. In the acceleration control, disturbance observer is used to estimate and compensate disturbance force applied to an actuator. In the disturbance observer, the disturbance is estimated with calculating acceleration based on...
We propose a robot control system utilizing semantic information behind robot-plans. Robots read the semantic information annotated to control programs, and utilize it for proper situation-recognition and rational action-generation. We try to develop a framework based on reusable and sharable representations among robots and humans. To this end, we construct an ontology of task world defining a systematized...
Summary form only given. The project Natural Language Understanding and Action Control started in 2001 as 5-year research project of a Grant-in-Aid for Creative Scientific Research supported by the Ministry of Education, Culture, Sports, Science and Technology, and Japan Society for the Promotion of Science. The research objectives are summarized as follows: to explore the relation between language...
