Abstract:
A practical intelligent assist device is provided that eliminates the complex use of force sensing weigh cells and vector interpreting software. By simplifying the input to a series of traditional voltage inputs, i. e. 1-4 volt signals, the use of standard available control componentry becomes available. Utilizing a series of such simplified inputs, including a load angle feedback, the processing of the vector math can be accomplished within a programmable logic controller (PLC). Outputs can then be simply generated to control a series of 0-60 Hz digital signals to drive direct drive motors.
