Tinuku ~ Researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) developed a system called C-LEARN to allow noncoders to teach a robot about various tasks just by giving some information and other robot demos are performing the task.

MIT's CSAIL developed a system allows users to teach skills to a robot to be automatically transferred to other robots that have different ways of sizing time and save costs for companies who want a variety of robots to perform similar actions in the real world.

"The combination of learning intuitions uses demonstrations with precision motion planning algorithms," says Claudia Pérez-D'Arpino, PhD student at MIT.

"Robotic approaches to perform new types of tasks they have never learned before, such as multistep assembly using both arms," Pérez-D'Arpino, says.

The research team tested the system on Optimus is a robot designed to isolate bombs and perform tasks such as opening doors, hauling objects, and removing objects from containers. Optimus's learning abilities transferred to the Atlas is a 6-foot high humanoid robot and weighs 400-pounds.

C-LEARN provides a knowledge base of information on how to reach and understand different objects that have different constraints. For example, tires and steering wheel have a similar shape, but to attach it to the car, the robot must adjust the arm differently.

The operator then uses a 3-D interface for a demonstration robot about a specific task indicated by a sequence of relevant moments known as "keyframes" for different situations. The robot automatically suggests a motion plan for the operator to approve or edit as necessary.

"This approach is actually very similar to humans learning something about the world, we can not miraculously learn from a demonstration, so we take new information and match it with previous knowledge of the situation and environment," says Pérez-D'Arpino said.

This system is part of a focus on adaptive learning approach. C-LEARN handles certain advanced tasks such as avoiding collisions or planning different sequence of steps for a specific task. But the team hopes for more insight that gives the robot a wider physical ability.

"Traditional programming of robots in real-world scenarios is difficult, tedious, and requires a lot of domain knowledge," said Julie Shah, MIT Professor.

"It is far more effective to train them by providing basic knowledge and a single demonstration.This is an exciting step towards teaching robots to perform the multiarm and multistep tasks required for the assembly and maintenance of ships or aircraft," Shah said.
