Dexterous Robotic Hands Manipulate Objects with Ease


The robot hand manipulates an object.

The researchers used a model-free reinforcement learning algorithm with deep learning, and something called a teacher-student training method.

Scientists at the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory (CSAIL) have designed a system to enable robotic hands to handle more than 2,000 different objects.

The researchers used a simulated hand with 24 degrees of freedom, and demonstrated that the framework could be adapted to a real robotic system.

The framework employs a model-free reinforcement learning algorithm that formulates value functions from environmental interactions, deep learning, and "teacher-student" training.

The "teacher" network is fed data about the object and robot in simulation, which it distills into observations similar to those found in the real world.
