Imperial College London team develops AI method to learn by imitation a little: master new real-world tasks with minimal demonstrations

In the ever-evolving landscape of robotics and artificial intelligence, an interesting and challenging problem is how to teach robots to perform tasks on completely unique objects, i.e. objects they have never seen or interacted with before. Answering this topic, which has long captured the attention of researchers and scientists, is crucial to transforming robotics. A robot must understand two objects and place them in a task-specific manner along a manipulation path in order to perform manipulation tasks that require interaction with them.

The robot needs to make sure the teapot spout and cup opening are aligned when pouring tea from the teapot into the cup. For the task to be completed successfully, this alignment is essential. However, objects in the same category often have somewhat different shapes, which complicates knowing the exact parts that should line up for a given activity. When it comes to imitation learning, this problem becomes more complex because the robot must infer task-specific correspondences from demonstrations without having any prior information about the items or their category.

A team of researchers recently approached this problem by framing it as an imitation learning task, focusing on conditional alignment across graph representations of objects. The team has developed a technology that allows the robot to pick up new object alignment and interaction skills from some examples, which serve as context for the learning process. They called this method conditional alignment because it allows the robot to perform the task with a new set of objects immediately after seeing the demonstrations, eliminating the need for additional training or prior knowledge of the object class.

Through their experiments, the researchers investigated and verified the design decisions they made regarding their methodology. These tests have shown how well their approach achieves learning with just a few snapshots for a variety of common real-world tasks. Their approach performs better than the baseline techniques, demonstrating its superiority in terms of flexibility and effectiveness when capturing new tasks across different objects.

The team developed a unique strategy to address the problem of enabling robots to quickly adapt to new objects and perform tasks they observed being presented to different objects. They have developed a flexible framework that performs well in sparse learning by using graph representations and conditional alignment, and their studies provide experimental evidence of this. Details of the project can be accessed at https://www.robot-learning.uk/implicit-graph-alignment. The videos available on their project webpage serve as further evidence of the success of the approach and its practical use in real-world situations.
