Durable, anthropomorphic hands
The final missing piece of robotic hardware needed to build intelligent androids is the human-level hand. Clone has built the first durable, 24 degree-of-freedom manipulator:
Thumb rotation
Fingers from left to right
Wrist movements
Natural pronation and supination of forearm
Locked elbow joint
Low-cost, biomimetic skeleton
Clone has developed a technique to chemically mold dense, biomimetic bones from materials that can be obtained almost for free.
Size and biometric characteristics are the same as human hand:
Includes half of arm bone
Full forearm and palm with all possible degrees of freedom
Total length of 60 cm
Custom portable hydraulic powering supply
Equipped with 500W BLDC motor
Water vane pump that supplies 400l/h 10 bar
Flexible, monolithic pressure distribution system
Water filtering
Flexible reservoir for 0.5l of purified water
Total weight of 4.3 kg
Proportional force valves
36 specially designed electro-hydraulic valves for McKibben muscles control.
Each valve weighs 26 grams
Pressure sensor in each valve for every muscle
Strength and flow control for every muscle
Proprietary artificial muscles
After 8 years of trial-and-error R&D, Clone invented a class of hydraulic McKibben muscles.
Robust to environmental perturbations and large payloads.
Build with materials that are cheap to manufacture.
As strong as human muscles.
Similar responses to human muscles
Over 650 000 cycles with 1kg load
27.5% contraction under 1kg load
0.3s full contraction time under 1kg load
Portable, lightweight suitcase
All system fits into small suitcase (46x33x16 cm), that weights 6kg(12.2lbs) which includes:
Clone Hand
Hydraulic power supply
All 36 valves
Battery pack 180W/h
Raspberry PI 4B 8GB
