An algorithm for bending robots is presented in this paper. The algorithm makes use of the features of bending process to solve three problems: procedure generating, targets calculating and obstacle avoidance. It generates procedure with two state machines and a knowledge library, calculates targets with heuristic rules, and avoids obstacles in joint space. The algorithm has been applied to manufacture...
In path planning, potential fields introduce force constraints to ensure curvature continuity of trajectories and thus to facilitate path-tracking design. In previous works, a path planning design by fractional (or generalized) repulsive potential has been developed to avoid fixed obstacles: danger level of each obstacle was characterized by the fractional order of differentiation, and a fractional...
We develop non-smooth motion controllers that enable redundant manipulators to perform surface tasks, that involve force/torque interactions. The robot joint rates are constrained within given limits. The end-effector is stabilized to a point, on the surface, and then tracks a trajectory on the surface, while respecting the input constraints and avoiding obstacles, and the same time applying a specific...
Active flippers for tracked vehicles are very useful to improve traversability on uneven terrain. However it is widely known that control of flippers also increases the work-load for operators, particularly where the vehicle and the operator are far apart. To reduce the work-load, we aim to realize a sensor-based autonomous controller of flippers to enable a ldquosemi-autonomous operationrdquo of...
With increasing number of aging people, taking care of the elderly will become more and more important for future society, especially for those elderly living alone. This paper presents an autonomous mobile robot Rola (Robot of LivingAid) , which can handle certain emergency conditions in a home setting to help the elderly through multi-modal sensing and control functions. The implemented functions...
