How Should We Teach Robots? A Comparison of Kinesthetic, Joystick, and Gesture-Based Teaching

The paper frames the work as imitation learningImitation & Reinforcement LearningImitation Learning (IL)Teaching a robot by showing it examples of how to do a task.. Start here because it defines what success means and which assumptions the rest of the method inherits.

This paper benchmarks three practical ways to teach robots manipulationManipulation & TasksManipulationUsing a robot arm or hand to move or interact with objects. tasks—kinesthetic guidance (physical hand-over-hand), joystick controlControl & PlanningControlThe method used to make the robot move the way you want., and hand gestures—showing that kinesthetic teaching beats the others for complex, contact-sensitive tasks like assemblyManipulation & TasksAssemblyPutting components together in a structured way., while joystick works best for simpler picking.
