Abstract
Various torque-limiting screwdriver devices, systems, and methods are disclosed. The screwdriver can include a body, a motor that is configured to rotate a screw engaged with the screwdriver, and a processor configured to control operation of the screwdriver. The screwdriver can have torque-limiting functionality, such as by monitoring the amount of torque applied to the screw and reducing or stopping rotation of the screw when certain torque-limiting criteria are met. In some embodiments, the screwdriver can be switched between manual operation by a user, and automated operation by a motor within the screwdriver. In some embodiments, the screwdriver can be attached to a robotic arm.
