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!

Dobot to Dobot Handshake!

We did it! We made a dobot magician talk to another one and make it start. We even added a VEX switch as an input to start the first one. It is easy to do, but one word of caution:

Never connect or disconnect any wires to the dobot while it is powered on; always power it down first. Damage may result!

Ok, now on to the good stuff. If you bought your dobot through InPosition HERE, not only did you get a $100 discount, you get access to the documentation to make this happen for free! just email us! This includes worksheets and wiring diagrams.

Tony Koppers, my senior EDD student has done all of the legwork to make this happen, so special thanks to him!
