Pneumatic Parts Feeder

Question:

Do you have any ideas for ways to teach students about parts feeders in industry?

Answer:

Imagine a project that incorporates VEX pneumatics, 3D printing, CAD design, and Robotics all in one! That’s exactly what we did here. I taxed one of my students with this “Going Beyond” activity: Design a pneumatic parts feeder using what you have learned in CIM class so far, and here is what he came up with!

Caz Students Present to SMEEF in Michigan

  Riley Lordon & Savannah Johnson, juniors at Cazenovia HS took what they learned in Computer Integrated Manufacturing (CIM) class last year and brought it to life in Michigan this week. They presented “Industrial Robots in the Classroom” at the SME Headquarters in Southfield Michigan to many members of the SME Education Foundation as well as their sponsors.

They built a robotic workcell which simulated a grinding operation that included an electric turntable parts feeder that they made, a grinder made out of VEX components, and a Dobot Magician robot. It was a closed loop system that used inputs and outputs with the Dobot to complete the task and then palletize the final product.

Dipping with the Dobot Magician

Pick and place and moving things around are staples of industrial robots.  Another reason to use robots in industry and automation is because of danger to humans. Robots can work in environments that are adverse to humans; especially toxic and/or adverse environments.

Sometimes the best way to pick up an object is with a suction cup or vacuum gripper.  This works especially well with very small objects as well as large, and provides a cheaper alternative to a mechanical gripper.

In this activity, you will perform a chemical dipping operation with a robot arm using the air pump kit and a vacuum gripper.
  • Go home
  • Pick up the cylinder from the pallet
  • Dip it in Tank 1 for 2 seconds
  • Move the object and dip it in Tank 2 for 2 seconds
  • Move the object and dip it in Tank 3 for 2 seconds
  • Move the part back to the pallet.

How do I make my Dobot Magician talk to a VEX Cortex?

Question:

How do I make my Dobot Magician talk to a VEX Cortex?

Answer:

It’s called handshaking and it is probably one of the more difficult tasks when working with robots and machines. We use an optical isolator so as not to damage any of the equipment with incompatible voltages, so be sure to see the website for the wiring diagrams. Watch this four minute video to see how it’s done!
