SUMMARY:4-bar mechanisms in nature: their function and potential for biomi
 micry - Prof Stuart Burgess\, University of Bristol

DESCRIPTION:Linkage mechanisms like 4-bar mechanisms are common in mammals
 \, birds\, insects\, fish and snakes. These mechanisms are interesting to 
 study but also have potential for biomimicry. As with engineering applicat
 ions\, 4-bar mechanisms in nature allow advanced mechanical design feature
 s such as complex motion paths or optimal location of actuators. The talk 
 will describe research carried out on four examples of linkage mechanisms:
  mammalian knee joints\; insect wing joints\; bird wings\; and fish jaws. 
 In each case\, the mechanism and its function will be explained and a bio-
 inspired design will be presented. A comparison will be presented between 
 engineered mechanisms and the mechanisms found in nature. Joints in nature
  tend to be non-planar with highly redundant soft actuators. However\, the
 re is still scope for a degree of biomimicry.\nStuart Burgess BSc\, PhD\, 
 CEng\, FIMechE\nStuart Burgess is professor of Engineering Design at the U
 niversity of Bristol. He was the lead designer for the solar array deploym
 ent on the world’s largest civilian earth-observing spacecraft (Envisat)
 . He also led the design and testing of the chain drive for the track bike
 s used by the successful British Olympic Cycling Team at the Rio Olympics.
  He has published over 150 scientific papers on the science of design and 
 has 7 patents on novel mechanism designs including the double-action worm 
 gear set. He has received several national awards for his designs includin
 g the Turners Gold Medal and Molins Design Prize awarded by the minister o
 f State for Trade and Industry.\n\n
