For internal parameters describing the design quantities, additional types may be used by adding user-specific types, for example, the transmission ratio for a gearbox. To overcome these problems, the mechanical structure was redesigned without the gearbox. The capstans allowed for large reductions in the drive speed without the use of reduction gearboxes that were noisy and heavy. Moreover, the gearbox had a considerable amount of inertia relative to the flexible manipulator hub. Thus, modelling and control of the system with this gearbox would require consideration of this additional vibration, increasing the complexity of the controller. A steel ring was clamped around the gearbox and a spring steel bar was used to clamp the steel ring to the mounting structure. These frictions are essentially located in the gearbox reducers. Friction in gearbox helps us fix the output shaft without consuming energy. One end directly drives the gearbox, the other has a wheel attached. To this end, the arm motors and gearboxes were selected so that the arm can move from fully retracted to fully extended, or vice-versa, in under 1.5 seconds. The actuation of these d. o. f. is made with a stepper motor coupled through a gearbox with a great reduction ratio, which increases the precision of the movements. Typically, the equations representing the output side of the gearboxes on a robot arm will need to be coupled to the system dynamics and integrated with a small step size. Helicopter gearbox diagnostics and prognostics using vibration signature analysis. Self locking worm gearboxes provide the required motor speed reduction, and allow the arm to be held in position without consuming any energy.
