  • Patent number: 10429851
    Abstract: A proximity sensor includes first and second sensors disposed on a sensor body adjacent to one another. The first sensor is one of an emitter and a receiver. The second sensor is the other one of an emitter and a receiver. A third sensor is disposed adjacent the second sensor opposite the first sensor. The third sensor is an emitter if the first sensor is an emitter or a receiver if the first sensor is a receiver. Each sensor is positioned at an angle with respect to the other two sensors. Each sensor has a respective field of view. A first field of view intersects a second field of view defining a first volume that detects a floor surface within a first threshold distance. The second field of view intersects a third field of view defining a second volume that detects a floor surface within a second threshold distance.

  • Patent number: 9744677
    Abstract: A robotic end effector includes a finger and at least one actuator. The finger extends from a proximal end to a distal end along a finger axis. The finger includes a first phalanx proximate the proximal end, a second phalanx proximate the distal end, and a knuckle joint including at least one vertebra interposed between and separating the first and second phalanxes. The knuckle joint is configured to permit the second phalanx to pivot relative to the first phalanx about a pivot axis transverse to the finger axis. Each vertebra has an axial thickness extending along the finger axis and a lateral width extending perpendicular to its axial thickness, and its lateral width is greater than its axial thickness. The at least one actuator is operable to move the second phalanx relative to the first phalanx about the pivot axis.

    Abstract: A mobile human interface robot that includes a base defining a vertical center axis and a forward drive direction and a holonomic drive system supported by the base. The drive system has first, second, and third driven drive wheels, each trilaterally spaced about the vertical center axis and having a drive direction perpendicular to a radial axis with respect to the vertical center axis. The robot further includes a controller in communication with the holonomic drive system, a torso supported above the base, and a touch sensor system in communication with the controller. The touch sensor system is responsive to human contact. The controller issues drive commands to the holonomic drive system based on a touch signal received from the touch sensor system.
