DobotStudio: The Basics

Question:

How do I get started with DobotStudio? There really isn’t much info out there yet on how to use my Dobot Magician Robotic Arm.

Solution:

Well, first off, here’s just the tip of the iceberg…. more to be added as I figure stuff out. This robot can be taught and record points quickly and easily, and is also the most accurate and affordable educational robot on the market. Here is a start to some basic ways to get going with a really incredible software/hardware combo that is DobotStudio/Dobot Magician. See the tutorials below… Most of them not much over one or two minutes… Use Control + F to find what your looking for!

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!

The VEX Testbed is boring….

Question:

The VEX Testbed is boring; do you know of another way to make learning RobotC programming more appealing to high school students?

Answer:

Well, in my classroom we build clawbots, then add all of the sensors to them. we then get to program the sensors on a real, mobile robot!  Kids love it and the culminating activity is a game where they get to drive the robots around; just like a real VEX competition.  In the meantime, they are learning how to program inputs and outputs, the difference between analog and digital, and the how closed and open loop systems work.

In the zipped folder above you will find the following documents:
  1. Clawbot Sensor Install: This document shows you how to install the sensors on the clawbot to complete some activities.
  2. Clawbot Checklist: This is a document that the students do screen captures of their RobotC programs on so that you can keep track of their progress as they go.
  3.  Cortex Wiring Diagram: An example of the Cortex wiring. I like to use a template in my class so each robot is the same; it makes troubleshooting easier. It looks like this:

If you make any changes for the better, please share them back with us so we can pass them along. Thanks for making it better!   Continue Reading

HOW DO YOU HANDSHAKE BETWEEN 2 VEX CORTEX’S?

Problem: How do you handshake with two VEX Cortex’s? I can’t seem to get it to work! Solution: I had to call in the big guns on this one; Jim is a RobotC programmer extraordinaire. He put together the tutorial below.  Not only that, but he and I wrote the powerpoint and the teacher’s notes that contains all the notes that show how to wire this and make it work. So if you are a PLTW teacher, most of this documentation is in the teacher’s notes!
We agree though; the programming piece was lacking. So here it is. Attached you will find an activity to do, including the programming to make VEX to VEX handshaking work. If you need to zoom in below, use Ctrl + mouse wheel in your browser, and it will zoom in and out!
