Abstract
Disclosed herein are embodiments related to braking joints in robotic systems. For example, an apparatus for collaborative robotics may include a first segment, a second segment, and a joint assembly. The joint assembly may include a stepper motor to control a relative position of the first and second segments, and a phase of the stepper motor may be shorted when the apparatus is unpowered.
Claims20
An apparatus for collaborative robotics, comprising:
- a first segment;
- a second segment;
- and
- a joint assembly, wherein the joint assembly includes a stepper motor to control a relative position of the first and second segments, and a switch to selectively short a phase of the stepper motor.
1 more element
An apparatus for use in a robotic system, comprising:
- a processing device to:
- identify a signal to brake a joint assembly, wherein the joint assembly is driven by a stepper motor, and in response to identification of the signal, cause a phase of the stepper motor to be shorted.
An apparatus for use in a robotic system, comprising:
- a processing device to:
- cause a phase of a stepper motor to be shorted to brake the stepper motor, and
- cause the phase of the stepper motor to not be shorted together to allow the stepper motor to move.
