Robots That Understand Contextual Commands

Posted by Boisen Ho on February 22nd, 2021

For example, if you put a specific tool in a toolbox and ask a robot to "pick it up," it would be completely lost. Picking it up means being able to see and identify objects, understand commands, recognize that the "it" in question is the tool you put down, go back in time to remember the moment when you put down the tool, and distinguish the tool you put down from other ones of similar shapes and sizes. Recently researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have gotten closer to making this type of request easier: In a new paper, they present an Alexa-like system that allows robots to understand a wide range of commands that require contextual knowledge about objects and their environments. The toolbox situation above was among the types of tasks that ComText can handle. If you tell the system that "the tool I put down is my tool," it adds that fact to its knowledge base. You can then update the robot with more information about other objects and have it execute a range of tasks like picking up different sets of objects based on different commands. CSAIL postdoc Rohan Paul, one of the lead authors of the paper. The team tested ComText on Baxter, a two-armed humanoid robot developed for Rethink Robotics by former CSAIL director Rodney Brooks. The project was co-led by research scientist Andrei Barbu, alongside research scientist Sue Felshin, senior research scientist Boris Katz, and Professor Nicholas Roy. They presented the paper at last week's International Joint Conference on Artificial Intelligence (IJCAI) in Australia. Things like dates, birthdays, and facts are forms of "declarative memory." There are two kinds of declarative memory: semantic memory, which is based on general facts like the "sky is blue," and episodic memory, which is based on personal facts, like remembering what happened at a party. Most approaches to robot learning have focused only on semantic memory, which obviously leaves a big knowledge gap about events or facts that may be relevant context for future actions.

From this knowledge base, it can then reason, infer meaning and respond to commands. With ComText, Baxter was successful in executing the right command about 90 percent of the time. In the future, the team hopes to enable robots to understand more complicated information, such as multi-step commands, the intent of actions, and using properties about objects to interact with them more naturally.
