Many care-givers for bedridden people cannot go out easily. To reduce this problem, we have developed a tele care network system with hoist trolley robot. The robot conveys some drinks for bedridden person. Using this system Care-giver can control robot from remote place talking with bedridden person like video phone. We developed mobile care terminal using cell phone, so care-giver can control robot from most place in Japan. For network system, we used common object request broker architecture(CORBA). Using CORBA, developer can extend system easily, so we can use many robots in this system. Then we tested the performance of this system. On remote terminal, the feedback delay on control robot was less than82.7ms, and the bandwidth which system required was1.6Mbps. On mobile terminal, the frame rate of movie from camera was0.36 frames per second(fps), and the feedback delay was about7seconds. We think that care-giver can control robot smoothly in broadband network system from remote terminal, and care-giver can confirm that robot works sequentially from mobile cell phone terminal.
