Abstract
In a robot having a first rotary shaft and a second rotary shaft driven by respective motors and extending in the same direction, the second rotary shaft is rotated while vibrating the first rotary shaft that is holding a load directly or indirectly, thereby rotating the first rotary shaft relative to a load. This enables calculating the gravitational torque of the load applied to the first rotary shaft.
