Abstract: A control system for a neck mechanism includes a perception system configured to track movement of an object, and a perception control system that controls a rotary motor to yaw a platform and controls a first linear actuator and a second linear actuator that is in parallel with the first linear actuator to pitch and roll the platform according to a target position of the platform. The perception system tracks movement of the object by estimating its position and pose in 3D space and the platform is moved according to a vision-based position and pose estimation result.

Abstract: A robotic assistant includes a wheeled base, a body positioned on the base, a foldable seat rotatably connected to the body, an actuator to rotate the foldable seat with respect to the body, and a control system that receives command instructions. The actuator is electrically coupled to the control system. In response to the command instructions, the control system is to control the actuator to rotate the foldable seat to a folded position or an unfolded position. The control system is further to detect whether an external force from a user has applied to the foldable seat, and release the actuator to allow the foldable seat to be manually rotated.

Abstract: A robotic assistant includes a base; an elevation mechanism positioned on the base; a display rotatably mounted on the elevation mechanism; a camera positioned on the display; and a control system that receives command instructions. In response to the command instructions, the control system is to detect movement of a face of the user in a vertical direction based on the images captured by the camera. In response to detection of the movement of the face of the user in the vertical direction, the control system is to rotate the display and actuate the elevation mechanism to the move the display up and down to allow the camera to face the face of the user during the movement of the face of the user in the vertical direction.

Abstract: A robotic walking assistant includes a wheeled base having a base and one or more position adjustable wheels connected to the base, a body disposed in a vertical direction, positioned on the wheeled base and having a handle, and a control system that receives command instructions. Each of the one or more wheels is slidable with respect to the base between a retracted position and an extended position in a direction that is substantially parallel to a surface where the wheeled base moves. In response to the command instructions, the control system moves the one or more wheels between the retracted positions and the extended positions.

Abstract: A display stand includes a frame, an actuated rotary mechanism coupled to the frame, a counterweight coupled to the actuated rotary mechanism and movable in a vertical direction during rotation of the display about the axis of rotation, and an elevation mechanism. The actuated rotary mechanism includes a display holder that is configured to mount a display to the frame and rotate the display about an axis of rotation. The counterweight and the display are located at opposite sides of a vertical plane that passes through the axis of rotation such that a combined center of mass of the display, the display holder, and the counterweight lies on the vertical plane. The frame is coupled to the elevation mechanism, and the elevation mechanism is configured to move the frame up and down.
