Abstract
An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.
Claims12
An exercise machine, including:
- an actuator;
- a motor;
- a cable coupled between the actuator and the motor;
- and
- a processor configured to:
- determine that a range of motion of a user of the exercise machine is between pre-determined motion thresholds;
- while the range of motion of the user is between the pre-determined motion thresholds, determine persistence, for at least a pre-determined period of time, of both:
- (1) a velocity of the cable being below a pre-determined velocity threshold;
- and (2) a tension applied by the user on the cable being above a pre-determined tension threshold;
- and
- in response to determining persistence, for at least the pre-determined period of time, of both:
- (1) the velocity of the cable being below the pre-determined velocity threshold;
- and (2) the tension applied by the user on the cable being above the pre-determined tension threshold, determine that the user should be spotted, wherein torque of the motor is reduced based at least in part on determining that the user should be spotted.
