MIT Has Built A Robot That Can Pack Groceries Without Crushing Your Chips

The scientists at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) came up with a revolutionary prototype of a robot designed in a lab to experiment on the ability of packing groceries without squashing fragile goods like chips. Unlike other robots in the past, this one does not build itself or use unorthodox sensors; its purpose is single-mindedly centered on effective and organic grocery packing.

Robots find packing groceries a tough job— surprisingly complex as they have to identify, grasp, and organize items that are not only diverse in size but also fragility. While typical packing robots focus on speed and space efficiency, CSAIL’s Grocery Packing Robot stands out. It values common sense in packing so that fragile items stay intact: an approach aiming at the satisfaction of end users. “We’re trying to focus on a metric people actually care about when you ask them what’s important for grocery packing,” elucidates PhD student Annan Zhang.

The robot operates with a small conveyor belt system that brings items within range of its grasper. A depth-sensing camera estimates the size and position of each item, allowing the robot to decide the best way to grasp it. The robot’s “fingers” are equipped with tactile sensors that provide feedback on the object’s delicacy, enabling it to assign a delicacy score to each item. This ensures that fragile items like bread and chips are placed on top, while sturdier items are packed below.

One of the robot’s standout features is its ability to plan ahead. For instance, if it detects a bag of chips followed by a can, it will temporarily set the chips aside to avoid damage. This forward-thinking approach mimics the way humans intuitively pack groceries, demonstrating a significant advancement in robotic capabilities.

Currently, the Grocery Packing Robot is a research prototype, with hardware and software that would need significant scaling for commercial use. CSAIL director Daniela Rus highlights the need for additional grasping modalities, more sensors, and enhanced reliability to make the robot viable for real-world applications. Though the current model is a tangle of wires and 3D-printed parts, future versions may become a staple in grocery stores, packing groceries with the precision and care of a human. For now, the robot remains in the lab, packing groceries that no one will eat, but showcasing the potential for a more intelligent and gentle robotic future.
