Robotic Hand Developed at UC San Diego Can Rotate Objects Using Touch Alone
A team of engineers at the University of California San Diego (UCSD) has achieved a major breakthrough in the field of robotics. They have successfully designed a robotic hand that can rotate objects using touch alone, without relying on visual input. This innovation was inspired by the effortless way humans handle objects without needing to see them directly.
Using a Touch-Sensitive Approach
The engineers equipped a four-fingered robotic hand with 16 touch sensors spread across its palm and fingers. Each sensor, which costs around $12, performs a simple function of detecting whether an object is touching it or not. This unique approach relies on numerous low-cost, low-resolution touch sensors that use binary signals to perform in-hand rotation.
Contrast to Other Methods
In contrast to other methods, which rely on a few high-cost, high-resolution touch sensors affixed to a small area of the robotic hand, this new approach minimizes limitations. Xiaolong Wang, the lead researcher and a professor of electrical and computer engineering at UC San Diego, highlighted the drawbacks of traditional methods. They limit the chance for sensors to come in contact with the object, thus limiting the system’s sensing ability. Additionally, high-resolution touch sensors that provide information about texture are not only difficult to simulate but are also prohibitively expensive.
The Power of Binary Signals
The team of engineers demonstrated that they don’t need intricate details about an object’s texture to perform the task. Simple binary signals indicating whether the sensors have touched the object or not are sufficient. These signals are easier to simulate and transfer to the real world, making the approach more practical.
Training the System
To train the system, the engineers created simulations of a virtual robotic hand rotating various objects with irregular shapes. The system considers which sensors are being touched by the object at each time point during the rotation. It also considers the current positions of the hand’s joints and their previous actions. Using this information, the system instructs the robotic hand on the necessary movements to rotate the object.
Testing the Robotic Hand
The researchers tested their system on the real-life robotic hand using objects that the system had not encountered before. The robotic hand successfully rotated a variety of objects, including a tomato, a pepper, a can of peanut butter, and a toy rubber duck, which presented the greatest challenge due to its shape. Objects with more complex shapes took longer to rotate, but the robotic hand maintained its hold and didn’t stall. It also demonstrated the ability to rotate objects along different axes.
Looking Ahead
The team is now focused on advancing their approach to tackle more complex manipulation tasks. They are currently developing techniques to enable robotic hands to catch, throw, and juggle objects. In-hand manipulation is a skill that humans possess naturally, but replicating it in robots is a complex endeavor. The researchers believe that granting robots this skill will expand the range of tasks they can perform.
A Step Forward in Robotics
This development signifies a significant advancement in the field of robotics, potentially paving the way for robots capable of manipulating objects in visually challenging environments or even in the dark. The ability to rely on touch alone opens up new possibilities for practical robot applications in various industries.
