The transmission mechanism is to transmit mechanical power from the motor assembly to the speed reduction mechanism. The axes of rotation of the output components of the speed reduction mechanisms are skew or intersected with each other. | 2022-06-16 |
20220184800 | MECHANICAL GRASPING END EFFECTOR WITH HORIZONTAL AND VERTICAL MOVEMENT - A mechanical device for grasping an object without a power source includes a receiver and at least one grabber assembly secured to the receiver. The grabber assembly includes first and second arms with proximal end portions and distal end portions, hooks disposed at the distal end portions, and a mechanical linkage disposed near the proximal end portion of the first arm and the second arm. The mechanical linkage kinematically couples the first arm to the second arm. Displacement of the first arm or the second arm against the object causes movement of the mechanical linkage and thus movement of the second arm or first arm, respectively. | 2022-06-16 |
20220184801 | CONTROLLING AN AUTONOMOUS WORKING DEVICE BASED ON PHYSICAL INTERACTION - An autonomous working device comprises at least one sensor configured to generate a sensor signal based on a physical interaction of the autonomous working device with a physical entity, at least one actuator configured to perform a working task, and a controller configured to generate a control signal for controlling the actuator. The controller is configured to evaluate the sensor signal, to determine a pattern of a physical interaction of the autonomous working device with a person and to generate the control signal based on the determined pattern of a physical interaction. | 2022-06-16 |
20220184802 | ROBOTIC SYSTEMS USING LEARNING TO PROVIDE REAL-TIME VIBRATION-SUPRESSING CONTROL - A robot control method, and associated robot controllers and robots operating with such methods and controllers, providing real-time vibration suppression. The control method involves learning to support real-time, vibration-suppressing control. The method uses state-of-the-art machine learning techniques in conjunction with a differentiable dynamics simulator to yield fast and accurate vibration suppression. Vibration suppression using offline simulation approaches that can be computationally expensive may be used to create training data for the controller, which may be provide by a variety of neural network configurations. In other cases, sensory feedback from sensors onboard the robot being controlled can be used to provide training data to account for wear of the robot's components. | 2022-06-16 |
20220184803 | ROBOT CONTROL, TRAINING AND COLLABORATION IN AN IMMERSIVE VIRTUAL REALITY ENVIRONMENT - System and methods to create an immersive virtual environment using a virtual reality system that receives parameters corresponding to a real-world robot. The real-world robot may be simulated to create a virtual robot based on the received parameters. The immersive virtual environment may be transmitted to a user. The user may supply input and interact with the virtual robot. Feedback such as the current state of the virtual robot or the real-world robot may be provided to the user. The user may train the virtual robot. The real-world robot may be programmed based on the virtual robot training. | 2022-06-16 |
20220184804 | ROBOT CONTROL - A method for controlling a mechanical system having a plurality of components interlinked by a plurality of driven joints, the method comprising: measuring torques or forces about or at the driven joints and forming a load signal representing the measured torques or forces; receiving a motion demand signal representing a desired state of the system; implementing an impedance control algorithm in dependence on the motion demand signal and the load signal to form a target signal indicating a target configuration for each of the driven joints; measuring the configuration of each of the driven joints and forming a state signal representing the measured configurations; and forming a set of drive signals for the joints by, for each joint, comparing the target configuration of that joint as indicated by the target signal to the measured configuration of that joint as indicated by the state signal. | 2022-06-16 |
