‘CyberGuy’: Robots repairing robots
Kurt Knutsson reveals how the Aloha Unleashed project showcases a dual-arm robotic system that performs tasks autonomously, demonstrating remarkable precision in robotics.
In a groundbreaking development, researchers have revealed the impressive capabilities of the Aloha Unleashed project. This project, led by Stanford Ph.D. Student Tony Z. Zhao and Assistant Professor Chelsea Finn of the Mobile Aloha team showcase the next level of robotic prowess.

Project Aloha Unleashed
The Aloha Unleashed project builds on the success of the original Aloha cleaning robot. In January, the research team captivated the world by demonstrating the cooking skills of an open source Aloha robot. Now they’ve gone a step further, focusing on complex tasks like tying shoelaces, hanging shirts, and even repairing other robots.

Improvements and innovations
The team behind Aloha Unleashed has made five key improvements to the robot’s design:
1) Improved manipulator arms: The Aloha 2 manipulator arms are the center of this project. These arms have been meticulously developed to improve performance and durability. Facing pairs of these arms allows for more complex tasks and fleet-scale data collection.
2) Smarter grippers: The scissor mechanism of the grippers has been replaced by a low friction rail. This modification allows the robot to grasp smaller objects with precision.
3) Advanced cameras: Smaller RealSense cameras with a wider field of view provide better visual information for the robot’s decision-making process.
4) Gravity compensation: A passive gravity compensation configuration, using commercially available components, supports the guide arms during teleoperation.
5) Simulation model: The team has created an improved simulation model that improves accuracy and visual fidelity. This model helps to train the robot for various tasks.

Robot repair
The robot helps DeepMind’s SARA-RT model in a fascinating demonstration by inserting a spare gripper/finger. This points to a future where robots will be able to repair each other autonomously.

Hang a t-shirt
Aloha handlers tackle the challenge of hanging a t-shirt on a hanger and placing it on a nearby shelf. Despite not having specific examples of adult t-shirts during training, the model generalizes successfully.
