Learning from demonstrations is key in robotics, but physical demonstration & teleoperation are slow and don’t scale well. We introduce L2D2, a sketch-based interface + algorithm that lets users teach robots by simply drawing trajectories on a 2D image of the robot environment.

This work enables more intuitive, scalable ways for humans to teach robots, making it ideal for households, assistive care, industrial automation, and more. With a sketch-based interface, even non-experts can express tasks, while the system maps sketches into real robot control.

This work is published in Autonomous Robots, a Springer Nature peer-reviewed journal. The study was led by @Shaunak__Mehta, with @dplosey, @herambnemlekar, and Hari Sumant. Paper: link.springer.com/article/10… Website: collab.me.vt.edu/L2D2/ Code: github.com/VT-Collab/L2D2

L2D2: Robot Learning from 2D drawings

Autonomous Robots - Robots should learn new tasks from humans. But how do humans convey what they want the robot to do? Existing methods largely rely on humans physically guiding the robot arm...
