Biomechatronics 103 (1)

  1. 1. Biomechatronics Eric Minaker October 15, 2013
  2. 2. What is Biomechatronics? ● Interdisciplinary science aiming to integrate mechanical and electrical elements with biological organisms ● Goal is to create new, innovative prosthetics that can restore mobility to human motor control that was lost or impaired
  3. 3. History of Prosthetics ● Ancient Egypt pioneered simple prosthetics ● First evidence of modern prosthetics in 1508 ● German mercenary created articulated metal hands after losing his right arm in battle ● In 1800 James Potts created the first prosthesis to use tendon movement to control the limb ● In modern times, prosthetics have have gained much larger ranges of motion and new interfaces to control their movement
  4. 4. Current Research in Biomechatronics ● MIT, Carnegie Mellon University, and Arizona State University are pioneering forces in the field ● MIT has been responsible for numerous scientific and technological breakthroughs ● Carnegie Mellon maintain a smaller lab that is able to research a few topics intensively ● Arizona State University has focussed on tactile feedback in hands and grip responses
  5. 5. MIT Research ● Muscle actuated fish ○ ○ One of the first biomechatronics research projects Uses frog leg muscles to power a robotic fish ● Neural control and implants ○ ○ Will allow for natural control of limbs with changing terrain Provides more accurate tactile feedback from prosthesis ● Bionic Skin ○ ○ Creates a seamless interface between human skin and contact surfaces of the prosthesis Allows for more natural movement
  6. 6. Carnegie Mellon University Research ● User specific prosthetic design ○ Plans to create a versatile testbed to rapidly create unique prosthetics based on a user’s needs ○ Not only custom molds, but interfaces, motors, and joints ○ Will reduce overall cost and help with chronic walking speed, falling, and pain associated with lower limb prosthetics
  7. 7. Arizona State University Research ● Grip responses ○ ○ Research into how hands react to gripping objects of varying shapes Focusses on pressure applied when rotating and handling oddly shaped objects ● Tactile sensor skin ○ ○ Like MIT’s bionic skin, would allow for accurate tactile feedback from the prosthetic Unlike current sensors used on hands, skin can be deformed and is conformable
  8. 8. Current State of Biomechatronics and Intelligent Prosthetics ● iLimb ○ ○ ○ Variable control for each digit Pressure sensitive skin Uses tendon and muscle activity to control digit and limb movement
