Teach Pendant
A teach pendant is the handheld operator terminal connected to a robot controller, used to jog the robot, record positions, write and edit programs and run them in manual mode, with an emergency stop and an enabling switch for safety.
The pendant has a display, often a touchscreen, jog keys or a joystick, an emergency stop button and an enabling device. Operators jog the robot in joint or Cartesian coordinates, move it to each required position and record points, then build programs with motion, I/O and logic instructions. Programs can be stepped through at reduced speed to verify paths before automatic operation.
Pendant programming is the traditional way to program industrial robots and remains common for small cells, for touching up points after a fixture change and for correcting programs generated offline. Modern pendants also show alarms, I/O states and diagnostics, and some offer graphical or wizard-based programming, particularly on cobots.
The enabling device is typically a three-position switch: motion is allowed only in the middle position and stops if the switch is released or pressed fully. Manual mode runs at reduced speed under ISO 10218 requirements. Programming on the pendant takes the robot out of production, which is a key reason for adopting offline programming.
Key points

- Includes an emergency stop and a three-position enabling device
- Manual mode operates at reduced speed as required by ISO 10218
- Programming on the pendant takes the robot out of production
Where AiVibe comes in
AiVibe designs and manufactures the AiAmbA AI Factory, whose edge devices and AI agents let people talk to robot controllers in plain language. Robotics perception is an AiAmbA use case, and robot safety functions follow ISO 10218 and never depend on the AI layer.
