Remote Control Handlers Patents (Class 414/909)
  • Patent number: 8186931
    Abstract: The powered hand truck has a chassis supported at one end by a single axle with two independently operable drive wheels. A prime mover is provided generally medially on the chassis, driving the drive wheels and powering the forklift mechanism. There is no operator console housing for the powered hand truck, as it is intended to be remotely controlled. A transmitter provides for specific and precise control of each drive wheel independently of the other, by using two drive wheel control switches. The powered hand truck has a caster wheel actuation strut housing over the caster wheel end of the chassis. A storage rack and dolly may be installed upon a suitable transport vehicle for transporting the powered hand truck. The hand truck forks engage the storage rack dolly, with the dolly translating along the rack to allow the truck to be deployed from, or loaded onto, the transport vehicle.

  • Patent number: 5754433
    Abstract: The computer-aided design system of the present invention is characterized in that a grasping force sensor 4 is mounted on that operating bar 3 at the front end of a manipulator 1 which is grasped directly and operated by an operator, and that the mechanical response characteristics of the system are varied on the basis of an output from the grasping force sensor 4. That is, the rigidity on the part of the manipulator is increased in response to a high grasping force during operation, since the rigidity of the hand is also high; and the rigidity on the part of the manipulator is decreased for a low grasping force during operation, since the rigidity of the hand is also low. In scenes in which a space on a computer screen defining no shapes is crossed by a cusor on the screen, a weak grip will lower the rigidity on the part of the manipulator, thus achieving the feeling of a smooth operation.

  • Patent number: 5116180
    Abstract: In a human-in-the-loop robotic control loop, the constrained forces and moments at the gripper (also called hand or end effector) of the manipulator are measured by a force-mement sensor. The resulting force and moment signals are scaled and fed as input voltages to motors in a hand controller to provide torques which oppose deflection of the hand controller. Thus, the operator feels the opposing torques which are proportional to the magnitude of the constrained forces and moments. The force feedback loop may be opened to selectively provide a passive control loop. In either the active or passive mode, the hand controller position signals may be selectively mapped to either gripper position signals or gripper velocity signals in order to control movement of the gripper in the desired manner.

  • Patent number: 4904514
    Abstract: A covering for a mechanical linkage comprises a material which is substantially impermeable to both liquid and particle contaminants and conforms to the outer surface of the mechanical linkage. Because the covering conforms to the surface of the mechanical linkage, the covering does not have loose portions that billow and rub together as the mechanical linkage operates. This lessens the possibility of pieces of the covering and contaminating material detaching and falling from the mechanical linkage. The covering also comprises access openings whereby the mechanical linkage can be serviced without removing the entire covering. In a preferred embodiment, the covering comprises a plurality of sections, each section having fasteners for securing the sections about the mechanical linkage. The separate sections can be individually removed and replaced in a relatively short period of time.
