    • Method for controlling a robot according to this invention lies in that, in controlling a robot that comprises shafts having one degree of freedom or a plurality of degrees of freedom, and where a dynamic load is applied to at least one of the above shafts, the shafts being driven by a servo motor via a speed reducer, the improvement is characterized in that the shaft to which the load is applied is moved in a load acting direction and thereafter is stopped.
      This invention is enabled by the discovery that the efficiency (normal efficiency) from the servo motor to the arm (shaft) forms an almost the same value relative to the efficiency (reverse efficiency) from the arm to the servo motor. A condition of transmitting the load from the arm is intentionally made and the load is made to establish equilibrium with the torque generated by the servo motor, thus reducing the consumption of electricity and the generation of heat.
    • 根据本发明的用于控制机器人的方法在于,在控制包括具有一个自由度或多个自由度的轴的机器人中,并且对上述轴中的至少一个施加动态载荷时, 轴由伺服电动机通过减速器驱动,其特征在于,施加负载的轴在负载作用方向上移动,然后停止。 通过发现从伺服电动机到臂(轴)的效率(正常效率)相对于从臂到伺服电动机的效率(反向效率)形成几乎相同的值可以实现本发明。 有意地从臂传送负载的条件,并且使负载与伺服电动机产生的转矩建立平衡,从而减少电力消耗和产生热量。
