What this does

We first used this hook as an end effector in this paper: Pulling Open Novel Doors and Drawers with Equilibrium Point Control. Advait Jain and Charles C. Kemp. IEEE-RAS International Conference on Humanoid Robots (Humanoids), 2009. This paper and others can be downloaded from the Heathcare Robotics Lab website (http://www.healthcare-robotics.com)

The hook was inspired by how humans sometimes use a finger or fingers to hook around a handle and pull something open. We also took inspiration from prosthetic hooks, which have been successfully used with remarkable versatility and effectiveness.


Image of the solidworks part for the hook that mounts on to an ATI Mini 40 Force/Torque sensor.
  • We designed the hook in Solidworks and printed it on a 3D printer.
    • Solidworks CAD file (hook.sldprt). This requires Solidworks 2009.
    • STL file will be uploaded soon. (hook.stl)
  • We also stuck some rubber on the hook. This can be seen in the images of the actual hook. The 3D printed hook is white and the rubber is black in color. We have bought the rubber sheets from http://mcmastercarr.com and used superglue to stick the rubber to the hook.
  • The mounting holes in the base of the hook match an ATI Mini40 force torque sensor. (http://www.ati-ia.com/products/ft/ft_models.aspx?id=Mini40)
