    • PROBLEM TO BE SOLVED: To provide a spherical wheel for an omnidirectional moving body and the omnidirectional moving body having a smaller number of components and excellent capability to overstride a step.
      SOLUTION: This spherical wheel 26 for the omnidirectional moving body is moved to a direction vertical to an overall wheel rotating shaft 16a and parallel with a traveling face by rotation of the overall wheel. To the same direction as that of the overall wheel rotating shaft 16a, the spherical wheel 26 for the omnidirectional moving body is moved by rotation of hemispherical wheels 15 in the case other than that where a rotating shaft of the hemispherical wheels 15 is vertical to the traveling face, and is moved by rotation of small wheels 17 in the case where the rotating shaft of the hemispherical wheels 15 is vertical to the traveling face. In addition, at the time of overstriding a step, the rotating shaft of the hemispherical wheels 15 is made horizontal while maintaining contact with the step. That is, the diameter of the hemispherical wheels 15 on which the step overstriding capacity depends is maximized, so as to enable overstriding of the step.

    • 要解决的问题:提供一种用于全向移动体的球面轮和具有较少数量的部件的全向运动体,并且具有超越台阶的优异的能力。 解决方案:用于全向移动体的球形轮26通过整个轮的旋转而移动到垂直于整个轮转轴16a的方向并与行进面平行。 在与整体轮转轴16a相同的方向上,用于全向移动体的球面轮26在半球形轮15的旋转轴垂直于其的情况下通过半球形轮15的旋转而移动 在半球形轮15的旋转轴垂直于行进面的情况下,通过小轮17的旋转而移动。 此外,在跨越阶梯时,半球形轮15的旋转轴在保持与台阶接触的同时水平。 也就是说,其中阶梯超载能力所依赖的半球形轮15的直径最大化,以便能够跨越台阶。 版权所有(C)2007,JPO&INPIT
