    Abstract: A nutrunner includes a housing, a motor with an output shaft rotatable about a first axis, a head including an output drive rotatable about a second axis, a transmission including a ring gear rotatable about the first axis, and a clutch mechanism. The clutch mechanism includes an adjustment collar rotatable about the first axis, rolling elements engaged with the ring gear, and a spring between the adjustment collar and the ring gear to bias the rolling elements into engagement with the ring gear. The clutch mechanism is configured to prevent the ring gear from rotating when a torque applied to the ring gear is less than a torque threshold, and to permit the ring gear to rotate when a torque applied to the ring gear is greater than or equal to the torque threshold. Rotation of the adjustment collar about the first axis adjusts the torque threshold.

  • Publication number: 20250165004
    Abstract: A method for evaluating robots in simulation, when executed on a computing device, involves the following steps: obtaining a robot description file created based on the physical properties of a robot, obtaining an environment description file created based on an environment, and obtaining an obstacle description file. A physics simulation engine creates a virtual environment based on the environment description file and obstacle description file. A virtual robot is created based on the robot description file. When the virtual robot navigates from the starting area to the ending area within the virtual environment based on navigation information, the physics simulation engine outputs simulation information. The robot navigation program generates and sends navigation information to the physics simulation engine based on the simulation information. When the virtual robot reaches the ending area, the physics simulation engine outputs evaluation information.
