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 use a switch as an input for the Dobot Magician?

Question:

How do I use a switch as an input for the Dobot Magician?

Answer:

CAUTION: NEVER PLUG IN OR UNPLUG WIRES FROM THE DOBOT WHILE IT IS POWERED ON! Always turn off the dobot first, and use the input output manual to plug into the correct port!

 Wire it like this:

Wire the VEX switch using a servo extension cable. Always wire black to black. Use pins GP5.2 and GP5.4 as shown in the diagram above.

Then in the software, trigger it like this:

  1. Be sure that you are in “Pro” mode by selecting it in the top middle of the Teaching and Playback mode.
  2. Set IO_5 to be equal to one on the right side of the screen.
  3. In this example above, the robot will go to it’s “Home” position and wait to be triggered by the switch in Line two.

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!
