This video demonstrates the application of a wireless head-joystick, that enables handicapped people who may not move their arms and legs to steer an automated wheelchair.

The following two videos illustrate a simulation software that advances the idea of a robotic device inspired by ringed worm’s locomotion. Its basic design is made up of an elongated body that is composed of a spring-style skeleton which is coated by a flexible skin. Our principle approach is to choose a shape memory alloy material for the skeleton, resulting in different spring forces exerted by the body under varying temperatures. The overall approach requires the elastic skin to prestress the whole body in its rest position, so that it can spatially extend when thermal energy is induced to the system, and relax when an inbuilt air cooling mechanism dissipates the heat.

This video demonstrates the use of natural language route descriptions in the mobile robot navigation domain. Guided by corpus analysis and earlier work on coarse qualitative route descriptions, we decompose instructions given by humans into sequences of imprecise route segment descriptions. By applying fuzzy rules for the involved spatial relations and actions, we construct a search tree that can be searched in a depth-first branch and-bound manner for the most probable goal configuration w.r.t. the global workspace knowledge of the robot. The applicability of our approach is shown by a real-world experiment where Rob instructs his automated wheelchair to navigate in an office-like environment.
