Arm prosthetic device
A system for powering a prosthetic arm is disclosed. The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.
1. A method of actuating a brake system, the method comprising:
actuating a motor, the motor operatively engaged with a cam rod;
actuating a cam rod upon actuation of the motor;
disengaging a first caliper from a first peripheral edge of a first brake rotor upon actuation of the cam rod such that the first brake rotor can freely rotate upon the disengaging; and
disengaging a second caliper from a second peripheral edge of a second brake rotor upon actuation of the cam rod such that the second brake rotor can freely rotate upon the disengaging.
2. The method of claim 1 , further comprising actuating a clutch, the clutch being operatively engaged with the motor and the cam rod such that the cam rod is actuated by the motor through the clutch.
3. The method of claim 1 , wherein the disengaging the first caliper includes disengaging the first caliper from the first peripheral edge of the first brake rotor independently from the second peripheral edge of the second brake rotor.
4. The method of claim 3 , wherein the disengaging the second caliper includes disengaging the second caliper from the second peripheral edge of the second brake rotor independently from the first peripheral edge of the first brake rotor.
5. The method of claim 4 , wherein the disengaging the second caliper further includes disengaging the second caliper from the second peripheral edge of the second brake rotor wherein the second brake rotor has a different diameter from the first brake rotor.
6. A method of actuating a brake system, the method comprising:
actuating a motor, the motor operatively engaged with a cam rod;
actuating a cam rod upon actuation of the motor;
engaging a first caliper with a first peripheral edge of a first brake rotor by a bias member upon actuation of the cam rod such that the first brake rotor is prevented from rotating; and
engaging a second caliper with a second peripheral edge of a second brake rotor by the bias member upon actuation of the cam rod such that the second brake rotor is prevented from rotating.
7. The method of claim 6 , further comprising actuating a clutch, the clutch being operatively engaged with the motor and the cam rod such that the cam rod is actuated by the motor through the clutch.
8. The method of claim 6 , wherein the engaging the first caliper includes engaging the first caliper with the first peripheral edge of the first brake rotor independently from the second peripheral edge of the second brake rotor.
9. The method of claim 8 , wherein the engaging the second caliper includes engaging the second caliper with the second peripheral edge of the second brake rotor independently from the first peripheral edge of the first brake rotor.
10. The method of claim 9 , wherein the engaging the second caliper further includes engaging the second caliper with the second peripheral edge of the second brake rotor wherein the second brake rotor has a different diameter from the first brake rotor.
