Key Findings
LinkerBot has demonstrated the LinkerHand O30, a robotic hand capable of performing complex tasks such as swapping playing cards, making a coin disappear, and pulling a toy car from a thin card. These demonstrations highlight the system’s ability to coordinate rapid finger movements to manipulate small, thin objects.
Technical Details
The O30 is designed to be integrated into existing robotic systems and weighs 730 grams. Its technical specifications include:
- Degrees of Freedom: 20, allowing for independently controlled movements.
- Control and Precision: The hand receives control commands 500 times per second and can return to a specified position with a deviation of 0.2 millimeters.
- Actuation Speed: Full open or close cycle in approximately 0.8 seconds.
- Load and Force: Supports loads up to 30 kilograms. The thumb exerts up to 24 newtons of force, four-finger grips generate 30 newtons, and five-finger grasps reach 70 newtons.
Background and Context
Founded in 2023, LinkerBot specializes in highly dexterous robotic hands for humanoid robots. CEO Alex Zhou stated in May that the company holds more than 80% of the global market for robotic hands with a high degree of freedom. Following a funding round in April, the startup was valued at approximately $3 billion. Current production is nearly 5,000 units per month, with plans to increase capacity to 10,000 units.
Significance and Outlook
The O30 is targeted at AI model training, advanced robotics research, and precision manufacturing within the aerospace, automotive, and electronics industries. LinkerBot’s broader product line includes hands capable of threading needles, playing the piano, and assembling electronic components, with current Chinese pricing ranging from $600 to $15,000. Zhou predicts that as manufacturing expands, prices could drop to $200 within three to five years, potentially leading to a future where the average person owns ten robots.
