Google Deepmind shares its latest AI research for everyday robots

Summary

Google DeepMind presents three new advances in robotics research: AutoRT, SARA-RT and RT-Trajectory.

The new advances are designed to improve the data collection, speed, and generalization capabilities of robots in the real world. The goal is to create robots that can understand and perform complex tasks without having to be trained or built from scratch.

AutoRT: Robot training with large AI Models

AutoRT uses large AI models such as Large Language Models (LLMs) and Visual Language Models (VLMs) in combination with specialized robot models to scale robot learning and train robots for real-world applications.

AutoRT can teach multiple robots simultaneously to perform different tasks in different environments. A VLM is used to understand the environment and the objects in view, and an LLM is used to suggest and select appropriate tasks for the robot to perform.

1) An autonomous wheeled robot finds a location with multiple objects. (2) A VLM describes the scene and objects to an LLM. (3) An LLM suggests diverse manipulation tasks for the robot and decides which tasks the robot could do unassisted, which would require remote control by a human, and which are impossible, before making a choice. (4) The chosen task is attempted, the experiential data collected, and the data scored for its diversity/novelty. Repeat. | Text and Image: Google Deepmind

During a seven-month evaluation period, the system safely trained up to 20 robots simultaneously and a total of 52 unique robots. This resulted in a rich dataset of 77,000 robot trials in 6,650 individual tasks.

AutoRT uses safety rules, including a robot constitution, to provide safety guidance to the LLM-based decision-maker when selecting tasks for robots.

The rules are based on Isaac Asimov’s Three Laws of Robotics. Human safety comes first, and the robot should avoid tasks that involve humans, animals, sharp objects, or electrical devices.

In addition, AutoRT uses established safety measures from classical robotics. For example, the robots will stop if the force on the joints exceeds a certain limit.

SARA-RT: Improving the efficiency of robotic transformers

SARA-RT (Self-Adaptive Robust Attention for Robotics Transformers) is a new system designed to make robotic transformers (RT) learn more efficiently.
