摘要:
A multi-joint robot having a function for estimating an amount of decrease in inner pressure of a gas spring, by means of a simple and low-cost structure, and a method for estimating the amount of decrease in inner pressure of the gas spring. The gas pressure within a cylinder of the gas spring decreases in connection with the motion of a lower arm associated with the gas spring. In the present invention, in view of a finding that the amount of decrease in inner pressure has a high correlation with a total movement distance obtained by integrating an amount of back-and-forth motion of a piston rod relative to a cylinder, an amount of decrease in inner pressure within the gas spring is estimated by calculating the total movement distance.
摘要(中):
具有通过简单且低成本的结构估计气弹簧的内压降低量的功能的多关节机器人,以及用于估计气弹簧的内压降低量的方法。 气弹簧的气缸内的气体压力随着与气弹簧相关的下臂的运动而减小。 在本发明中,考虑到内压降低量与通过将活塞杆相对于气缸的往复运动量相加而得到的总移动距离高度相关, 通过计算总移动距离来估计气弹簧内部压力的降低。
