| Popis: | 98 In this thesis, the development of a new type of power wheelchair is presented. This wheelchair’s chassis equips 4 power-steered- standard-wheel modules, which makes wheelchair can move in any direction, including lateral translation, not only overcomes the limitation of indoor space, but also increases the wheelchair’s mobility. Moreover, the wheel module is very energy efficient; compared to the traditional omni-wheels, this module can save about 30% energy. On the other hand, to avoid press sore due to long periods of sitting, a new reclining system is utilized. Because the wheelchair could be separated into up-part and down-part, when moving the link of two parts by a ball-screw could adjust users’ sitting posture. Besides, the distance between front wheels and rear wheels can also adjust users’ sitting posture, making not only increasing the angle of seat-changed but also adjust wheelchair’s position of gravity center, avoiding gravity center not between front wheels and rear wheels what could lead to wheelchair fall down. |
