VEX IQ controller and brain not communicating.

The communication issue can cause by several things.. I want to start by making sure that all the hardware has the latest firmware installed…

Please install the VEXos firmware utility. It can be found at

Once you have it install.. do the following.

  1. Start VEXos
  2. Have the battery in the brain with no other items connected.
  3. Connect the brain to computer with the USB to mini cable
  4. Turn on the brain.
  5. VEXos should see the brain and inform you if an update is needed…
  6. If need, follow the instructions on the screen… It’s pretty easy… If the brain switches off during the update, just turn it back on…
  7. Then disconnect the brain from the computer and attach the controller to brain with network cable
  8. Plug the brain back into the computer… Check if controller needs to be updated, if so, update…

NOTE: Once we figure out the communication issue, I would suggest/recommend plugging all sensors and motor into the brain to have them updated…

Once the controller and brain is updated…

  1. unplug brain from computer…
  2. With the network cable still attached to brain and controller, turn on the brain….
  3. Wait about a minute… turn everything off
  4. Disconnect the brain from the controller
  5. Turn the brain on and then the controller on
  6. There should be connection made and indicated on the LCD display (top right corner) it would like a wifi signal….

The VEX IQ rechargeable battery pack has died. It won’t turn on and if I try to charge the battery the charger just blinks orange/red.


The flashing red light is a common issue… follow these steps

1) Connect the brain to a wheel or gear with an axle. (have nothing else connected to the brain)
2) Insert the battery into the brain
3) Then spin the wheel/gear for a couple of minutes
4) This action actual charges the batter a little.
5) Remove the battery and place in on the charger for a complete charge.

When you place the battery on the charger it should be a solid red.

The New 2.4 GHz Radio for the Controller and Robot Brain

2.4 GHz

We have some news and updates to share related to radios in the VEX IQ product line.

The VEX IQ Super Kit (P/N: 228-2500) and Starter Kit with Controller (P/N: 228-3060) will now come with 2.4 GHz radios (P/N: 228-3015) instead of 900 MHz Radios (P/N: 228-2621) in the US and Canada.

Individual 2.4 GHz radios are also now available for purchase in the US and Canada. The 900 MHz radio has been discontinued and is no longer available. The retail price of the 2.4 GHz radio is the same as the 900 MHz radio.

There is no functionality difference between the two radios besides the frequencies they operate on. The 2.4 GHz radios are in black plastic compared the the grey plastic of the 900 MHz radios. These radios cannot be mixed and matched – a Robot Brain and a Controller both need to have the same type of radio to communicate to each other.

Update your firmware! The 2.4 GHz Radio requires Robot Brain firmware v1.10 or newer and Controller firmware v1.02 or newer. See for more information.

What’s an Electroporation and How did Afinia help make it?

We used the Afinia 3D printer to construct an electroporation device that shocks algae to experiment on releasing lipids. This was a combined  effort between our Professional Technical class and our Advanced Biology. It was amazing how accurate it printed.
