Estimating the term…
A wireless lifting assist device includes a pulley driven by an actuator which is attached to a ceiling. An end-effector is suspended, via a line, from the pulley and interfaces the object to be maneuvered. The wireless lifting assist device further provides an instrumented glove worn by an operator. The glove measures the contact force the operator is exerting on either the object to be moved or the lifting assist device and generates a set of contact signals representing the contact force. The contact signals are transmitted to a controller. The controller generates a set of command signals to control the actuator as a function of the operator contact force such that a predetermined percentage of the force necessary to lift or lower the load is applied by the actuator, with the remaining force being supplied by the operator. The object thus feels lighter to the operator.
A lift assist device for lifting and lowering at least one object, among other components, comprising:
A lift assist device for lifting or lowering at least one object, including an actuator arranged to turn a pulley, a line wound on said pulley and connectable to said object, a controller controlling operation of said actuator, an instrumented glove wearable by a human hand, wherein said instrumented glove includes at least one force sensing element for detecting an operator-applied force on said lift assist device or said object, said lift assist device comprising:
A method of operating a lift assist device, comprising the steps of:
