Abstract: A mechanical arm includes a first link connectable to a surface, a second link, a third link, a fourth link, and a fifth link that are coupled to one another in series, and an end effector connectable to the fifth link. The end effector is rotatable about an axis of rotation same as an axis of rotation of the fourth link, and rotatable about an axis of rotation orthogonal to the axis of rotation of the fourth link. The first link, the second link, the third link, the fourth link, and the fifth link are collectively structured and configured to rotate such that the end effector is actuatable to a workspace under the surface.

Abstract: A robotic assistant includes a wheeled base, a storage unit including drawers, a foldable arm connected to a top of the storage unit and including an end of arm tooling (EOAT) connected to a distal end of the foldable arm, an elevation mechanism positioned on the wheeled base and used to move the storage unit up and down, and a control system that receives command instructions. In response to the command instructions, the control system is configured to move the wheeled base, open or close the one or more drawers, actuate movement of the foldable arm and the EOAT to pick up and place external objects from/to a determined location, and control the storage unit to move up/down.

Abstract: A robotic hand includes a baseplate, a finger having multiple phalanges that are rotatably coupled to one another, a first of the phalanges having a first end rotatably coupled to the baseplate and a second end and a second of the phalanges rotatably coupled to the second end about an axis of rotation, an actuating mechanism mounted on the baseplate, the actuating mechanism configured to actuate rotation of the plurality of phalanges, and a tendon having opposite ends that are respectively attached to the second of the phalanges and the baseplate. The second of the phalanges has an engagement portion arranged around the axis of rotation, and the tendon is wrapped around a portion of the engagement portion to generate a force acting on the second end of the first of the phalanges, causing the first of the phalanges to rotate from a flexed state to an extended state.
