What is the role of a 'teach pendant' in robot programming?

The role of a 'teach pendant' in robot programming is primarily to allow operators to manually control the robot and input programs. This handheld device acts as the interface between the operator and the robotic system, facilitating direct interaction. Operators can use the teach pendant to control the robot's movements in real-time, which is particularly useful for programming complex tasks that require precision. By guiding the robot through specific paths, as well as inputting commands and instructions, the teach pendant enables the creation and modification of the robot's operational routines effectively.

This control mechanism is essential in various settings, from industrial environments to research and development, where precise and customized programming is necessary for successful robot operation.
