Robot arm and methods of use
A robot arm and method for using the robot arm. Embodiments may be directed to an apparatus comprising: a robot arm; an end effector coupled at a distal end of the robot arm and configured to hold a surgical tool; a plurality of motors operable to move the robot arm; and an activation assembly operable to send a move signal allowing an operator to move the robot arm.
1. An apparatus, comprising:
a robot arm;
an end effector coupled at a distal end of the robot arm and configured to hold a surgical tool;
a plurality of motors operable to move the robot arm; and
an activation assembly operable to send a move signal allowing an operator to move the robot arm,
wherein the activation assembly is in the form of a bracelet on the end effector.
2. The apparatus of claim 1 , wherein the end effector further comprises a load cell operable to detect and measure force applied to the end effector.
3. The apparatus of claim 2 , wherein the load cell is in communication with a motor driver of the plurality of motors by way of a microcontroller unit.
4. The apparatus of claim 2 , wherein the microcontroller unit and/or a motion controller receive information on the force applied to the end effector measured by the load cell and control the plurality of motors to replicate the motion and direction of the force applied to the end effector.
5. The apparatus of claim 2 , wherein the end effector comprises a saddle joint, the load cell being coupled to the saddle joint.
6. The apparatus of claim 1 , wherein the activation assembly comprises a primary button and one or more primary activation switches, wherein primary button is disposed upon the one or more primary activation switches, wherein depression of the primary button is required to send the move signal.
7. The apparatus of claim 6 , wherein the one or more primary activation switches comprises two or more primary activation switches activated by the primary button, wherein depression of at least two of the primary activation switches is required for the operator to move the robot arm.
8. The apparatus of claim 5 , wherein the primary button comprises a ridge that encircles the end effector.
9. The apparatus of claim 5 , wherein the activation assembly further comprises a secondary button operable to select functions, modes, and/or acknowledge information communicated to an operator.
10. The apparatus of claim 9 , wherein the primary button comprises a ridge that encircles the end effector, and wherein the secondary button comprises a ridge that encircles the end effector.
11. A method of moving a robot arm comprising:
depressing a primary button on an activation assembly;
applying force to the activation assembly;
sensing the force with a load cell;
communicating force to a computer processor; activating motors within robot arm using the computer processor; and
moving the robot arm with the motors in the direction of the applied force,
wherein the primary button comprises a ridge encircling an end effector coupled to the robot arm, the end effector holding a surgical tool.
12. The method of claim 11 , wherein depressing the primary button activates one or more primary activation switches.
13. The method of claim 12 , wherein moving the robot arm requires activating of at least two primary activation switches.
