    摘要: An object of the present invention is to prevent unnecessary driving stop of a stepping motor. A robot arm section includes a robot arm, a stepping motor 31a, a motor driver 31b, an encoder 31c and a step-out detection section 31e. The robot arm has a joint J1. The stepping motor generates power for operating the joint. The motor driver drives the stepping motor according to a target angle. The encoder outputs an encoder pulse every time a drive shaft of the stepping motor rotates by a predetermined angle. The step-out detection section detects a step-out of the stepping motor based on the target angle and a current angle of the stepping motor that is identified based on the encoder pulse. When the stepping motor does not recover from the step-out before a predetermined grace time elapses from a time at which the step-out is detected, the motor driver stops driving the stepping motor at the time point at which the grace time elapses.

    摘要: The disclosure includes a method and a robot for projecting the one or more graphics on the surface of a user environment. The method may include determining robot velocity data describing one or more of an angular velocity and a linear velocity of the robot. The method may include determining graphical data describing one or more graphics for projection on the surface of a user environment based on the angular velocity and the linear velocity of the robot. The one or more graphics may include one or more arrows describing a past behavior of the robot and a pending behavior of the robot. The method may include projecting the one or more graphics on the surface of the user environment so that a user present in the user environment with the robot may have access to information describing the past and pending behavior of the robot.
