In the top menu in RobotC, go to Robot / Platform Type / VEX Robotics flyout menu and make sure it’s set to VEX 2.0 Cortex.Start with robot and joysticks turned off.So this is why I’m writing this post-hopefully I can save some of you a bit of time on this one. We had a little difficulty getting this item set up and working, and then a little more difficulty getting it to work well after that. Then the joystick continues to talk to the cortex via the VEXnet keys, as it does during driver control. The other side of the Magic Widget has a different type of cable (looks more like a large, flat telephone wire) which runs from it to the “Program” port on the back of your main joystick (photo below). The other end of the USB gets connected to a Magic Widget (rectangular orange box, photo at right). So how does this miracle occur? As shown in the image at right, the cable is a 3-part item-the first section is USB, which plugs into your computer, the same way as non-wireless downloading.

Click the “start” button on the RobotC debug-window-popup box to enable normal robot functionality and competition switch.

With wireless downloading, mirroring the steps above:

Cycle the power off & on for the robot & joysticks, just to make sure it’s gonna work right.

Plug in the orange programming USB cable.

Unplug the VEXnet key may be more or less of a pain, depending on where it is on the robot.

Move the robot over to where the person with the computer is, or vice versa.

Without wireless capability, every iteration of programming involves the following: 60 seconds of trying to get everything just right with teeny changes and trying again and again. Think about programming autonomous-or even better, autonomous skills. wireless (b) Hardware setup and Cool add-on product (c) Using it and What’s that button for? (d) What if it doesn’t work? and (e) Additional resources.

Tons of code available to look at, use, and learn from on the VEX Forum, the RobotC Forum, and YouTube.Īs an added bonus, our team will no longer get Forum users answering our eas圜 questions with “You should switch to RobotC.” Gee, thanks.Ī condensed table of contents: (a) Wired vs.

You can actually do sophisticated programming.Wireless debug/sensor data ( subject of another post).In order to make use of this feature, you need to purchase the VEX wireless downloading cable, officially known as the “ Programming Hardware Kit.” Cost: $50 I got mine on eBay for about half that - it’s worth it to check eBay every now & then! There’s a lot of things I like about RobotC so far, and perhaps the most time-saving item is wireless downloading.
