TRANSCRIPT
THE DEKA ARMMICHAEL HEATH
PROBLEM BEING SOLVED
• Loss of upper limbs in war
• Paralysis
• Gives use to arm, isn’t just a “fake” arm
HISTORY OF PROSTHETIC ARMS
• First prosthetic arms thought to be used 1,000 years ago
• Movable joints with control used in early 1800s
• US government agency for advancing prostheses formed in 1945 after WWII
• Largely unchanged since then
• The standard of care today is a body-powered “hook”
CURRENT STATE
• The DEKA or “Luke” arm- Gen 1, 2, and 3
- 3 types: RC, HC, and SC
- 12 Dimensions of motion and counting
GEN 1 (GENERATION 1)
• Project started at DEKA in 2006
• Simultaneous control of multiple powered degrees of freedom
• Advanced grasp control
• Touch feedback
• Strength, range of motion, and speed to perform daily activities
• Tolerance to outdoor environments
• Advanced control
THE “LUKE” GEN 2
• Refinements made to Gen 1 prototype
• Designed for clinical study platform
• Able to support up to 3 different amputations levels (RC, HC, SC)
• Extensive testing by subjects helped to give feedback to support GEN 3
3 CONFIGURATIONS
• Radial
• Humeral
• Shoulder
THE “LUKE” GEN 3
• 10 degrees of freedom
- 5 brushless and 5 brushed DC motors
• 6 pre-programmed hand grips
• Rechargeable Li-Ion battery
• Multiple user input devices available ( foot sensors)
LIMITATIONS
• Price: cold start at over $100,000 apiece
• Short life span
• No “one size fits all”
• Small market
• Not fully waterproof
FUTURE DIRECTION
• New DEKA arm in testing/developing stages
• Clinical trials performed
• Completely controlled by thought
• Electrodes implanted into brain
• Arm is “trained”
