Oar Grip Project, ENGR 111 (Week Oct. 27- Nov. 1)

 Prototype 3 & 4 construction:

 

3:

  • Kept glove style from prototype 1 
  • Included palm padding and 3D attachment from prototype 2

 

 

Note* 

Prototype 3 velcro is unglued (in order to transfer to later prototype design) 

 

4:

  • Kept wrap design from prototype 2 
  • Included revitted attachment from prototype 1 
  • Kept finger restraints (but were later removed during testing because they made the diameter of the attachment too small to fit around oar

 

 

Note* Triple check diameter to ensure it fits on oar grip 

 

Next steps: 

 

  • Use a smaller nub (plastic piece on the end of the smooth 3D printed piece) to ensure full range of motion
  • Make sure finger restraints don’t wrap around the interior of the attachment (The portion tangent to the oar) 
  • More freedom around wrist to allow feathering 
  • Include the finger wrap on next prototype 
  • Incorporate gear motion to facilitate feathering
