YOR: Your Own Mobile Manipulator for Generalizable Robotics
YOR is an open-source, low-cost, and modular mobile manipulator designed to provide affordable whole-body mobility and bimanual manipulation capabilities for robotics research.

Imagine you want to teach a robot how to help out around the house—things like loading a dishwasher, watering plants, or picking up laundry. Currently, you have two bad options: you can buy a "super-robot" that costs as much as a luxury car (and is too big to fit in your kitchen), or you can use a "toy-robot" that is too weak to lift a laundry basket and can’t reach the top shelf.
Researchers have created a "Goldilocks" solution called YOR.
What is YOR?
Think of YOR as a highly capable, budget-friendly Swiss Army Knife on wheels. It isn't just a robotic arm stuck on a vacuum cleaner; it is a carefully designed "whole-body" machine.
Here is how it works, using some everyday analogies:
1. The "Skater" Base (Omnidirectional Mobility)
Most robots move like a car—they have to turn forward to go left or right. YOR moves like an ice skater or a professional dancer. Because of its special "swerve drive" wheels, it can slide sideways, spin in place, or move diagonally instantly. This means it can wiggle through a crowded living room without needing a huge turning radius.
2. The "Accordion" Lift (Vertical Reach)
Imagine a person who can instantly grow taller or shorter. YOR has a telescopic lift in its middle. This is like an accordion or a professional camera tripod that extends upward. This allows the robot to reach down to pick up a dropped sock on the floor, and then "stretch" its torso up to grab a cereal box from a high shelf.
3. The "Human-Like" Arms (Bimanual Manipulation)
Instead of having one clumsy claw, YOR has two arms, just like you. This allows it to do "teamwork" tasks—like using one hand to hold a heavy box steady while the other hand opens a lid. The arms are also "compliant," which is a fancy way of saying they are "springy" rather than "stiff." If the robot bumps into a table or a person, it doesn't smash into it like a hammer; it yields slightly, like a human arm would, making it much safer to be around.
4. The "Brain" and "Eyes" (AI and Navigation)
YOR uses smart cameras (like the ones on your smartphone) to see the world in 3D. It builds a mental map of your house, much like how you can navigate your bedroom in total darkness because you have a "map" in your head. It can even see a person walking in front of it and say, "Excuse me!" by recalculating a new path around them in real-time.
Why does this matter?
The most important part of YOR isn't just what it does, but what it costs.
In the world of robotics, most high-end machines are "black boxes"—they are expensive, secret, and impossible for regular students or researchers to tinker with. YOR is "Open Source," meaning the creators have shared the "recipe" (the blueprints and software) with everyone.
By keeping the cost under $10,000 (instead of $80,000!), they are essentially democratizing robotics. It’s like moving from a world where only billionaire tech companies can build computers, to a world where anyone with a garage and a dream can build a robot that learns to help at home.
