First strategy is the selection of a gait relying on locomotion rewards. The locomotion reward has been proposed as an indicator for selection algorithm based on Falling Risk and the moving speed. This strategy has achieved a capability of large changes of uncertainties, such as a steep slope. Second strategy is adjustment of moving speed by the extended locomotion reward that explicitly shows the relationship between the moving speed and Falling Risk. The robot aims at the maximum moving speed without a falling, and removes small changes of uncertainties as a result. We performed an experiment in order to confirm effects of two strategies in an environment that includes a rough terrain as a small uncertainty and two steps as a large uncertainty. The robot improved the moving speed about 37.5% from the case of only using the gait selection strategy.

However it is need to develop quantitative evaluation methods for the catheter trajectory inside vasculature phantoms. In this study we present two technologies developed for that purpose. First we present models of vasculature made of epoxy resin with higher sensitivity for photoelastic

They propose this strategy for a neural-network-based controller to be generalized with the higher level control based on artificial intelligence and to acquire knowledge heuristically. This system comprises two levels: a learning level and an adaptation level. The neural networks are used for both levels. The learning level has a

We propose a prototype model of an underwater microrobot utilizing an ICPF (ionic conducting polymer film) actuator as the servo actuator to realize swimming motion with 3 DOF. A biomimetic fish-like microrobot using the

Friction identification and modeling is the first step towards compensation for its effect. We propose an identification method and modeling of friction forces at the prismatic joints of a six d.o.f. hydraulically powered parallel link manipulator.
