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!
I can’t seem to get my encoder to work no matter what I do! It will only ever return a value of 0 or 1, and only for a moment. What’s up?
Well, did you restart your software and hardware? Then check this out! I’ll bet you have another analog sensor plugged into your cortex, like the sonar…. Found this after searching the web…. If using another analog sensor, the Quad Encoder MUST be plugged into a higher number port. Really? Yup. See the snip below. Spent at least a day on this then found the documentation on line, switched the ports with the sonar sensor so that the encoder was on 8 & 9, and the sonar on 4 & 5, and viola! Success! Try it! Also… we NEVER got the error as shown below… It just didn’t work. Download the whole VEX pdf here: Quadrature+EncodersContinue Reading
