As a tool to serve the elderly and disabled people, intelligent wheelchair may work in spacious and dynamic environments, such as parking lot. One difficulty of working in such scenarios is spaciousness and large scale which increases the difficulty of mapping. And the other is that there are various dynamic obstacles with different mobile frequency in the environment, which poses a new challenge...
The problem of door opening is very fundamental for mobile manipulators operating in domestic environments. In order to successfully achieve the door opening task with wheeled mobile redundant manipulators, a manipulability improving scheme is proposed and investigated in this paper. The scheme treats the wheelchair and the manipulator as a whole system and can improve the manipulator's manipulability...
A navigation system based on hybrid map for intelligent wheelchair is presented. The system is consisted of hybrid map building, localization, path planning and trajectory following. The hybrid map includes a series of small probabilistic grid maps (PGM) and a global topological map (GTM). They are built simultaneously and easily using the human-guided method. Then on the hybrid map, the localization...
Shared control is a common used method for human and wheelchair cooperation. However, most of the previous shared control methods didn't think much of the effect caused by the difference in the user's control ability. The control weight of a user in these methods is irrelevant to the user's capability or the driving conditions. In this paper, a dynamic shared control method is proposed to adapt wheelchair's...
To keep up with the wide-ranging, fast-moving robotics field, education must be adaptive and multidisciplinary. In this paper, integration of PSoC technology with educational robotics is presented. Both of the advantage: flexibility in hardware for PSoC and modularized robot components are fused. This integration balances research and implementation fundamentals by reinforcing course work with intensive...
