GRIPPER PROJECT

I worked in a team of five to design a light motor-powered gripper capable of holding a two pound object under a lot of centripetal force with a limited budget and tight deadlines. If the object dropped 0.1 inches, the group failed. We were among the first three groups to have a functional gripper.

DESIGN

  • I designed almost all of the parts in Solidworks.

  • FEA was used to ensure no part would fail

  • The 3D printed parts were oriented so that they were strong enough in each direction to avoid failure

  • The design of each of the parts accounted for the error of their manufacturing process.

MANUFACTURING

  • A mixture of laser cutting, milling, and 3D printing were used to manufacture the gripper

​

  • I worked on the 3D printing aspect to ensure that there were sufficient supports and that the part was strong enough relative to the direction of the forces being exerted
