In the summer of 2017, I built this zipper robot using 2 motors and a 3D printer. As its name says, it’s a cool robot that can both zipup and unzip a zipper. You can build one for yourself as well. I have shared the design of this robot as a .stl file here.
Steps to build one :
1) 3D print the alterations.stl file using a 3D printer
2) Use any superglue (I used loctite) to affix a flat rubberband on the sides of the pulley as shown in the Fig. It helps increase grip by providing friction
3) Place the pulleys from the top of the robot (through the hole provided)
4) Insert the motors, axle through the holes of the pulley.
5) Power up the motors using a 3-5V 1A power supply and watch the robot in action !.

For the motors, I used 2 x Dc geared high torque motors from Amazon.

Robots and Zippers? Is there a robot for every task imaginable nowadays? Well maybe not quite (yet), but this Cool Zipper Robot which zips up and down has grabbed our attention.
