June Release Note

For the June 2013 release of VEX IQ, the software in the Robot Brain and VEX Controller will support wireless driving via an easy to use built-in program. In August, a firmware update will be available to all units. The update will support programming from ROBOTC. The update will also support Port Mapping of motors and switches from the LCD. Various other features and enhancements will be included.

The VEX IQ system makes Firmware Updates quick and easy. All electronic components can be upgraded including the Robot Brain, VEX Controller, Smart Motors, and sensors. The VEX Firmware Utility for Windows will support firmware upgrades.


Smart Device Ports

The VEX IQ Robot Brain has 12 identical Smart Ports. Just plug any VEX IQ device into any port. The device is automatically detected. Smart Port devices include: Smart Motor, Distance Sensor, Color Sensor, Gyro Sensor, Touch LED, Bumper Switch, and Angle Sensor.

Build-and-Go with Built In Programs

The VEX IQ Brain comes loaded with programs that get you up and running quickly. No computer or programming required. The driver control program give you instand control of up to four drive motors and four additional mechanism motors, plus features for limit switches. Multiple pre-loaded autonomous programs allow robots to move by themselves using sensors. Custom programs allow you to create your own robot program right from the LCD screen.

Simple LCD Interface

The backlit LCD interface make VEX IQ simple to use. Using the 4-button interface, you can start your favorite program, reverse a motor, and even create your own custom program. Your ROBOTC programs can write messages on-screen to customize your robot and simplify program debugging. Smartphone like icons keep you in touch with your battery and wireless connection.

Go Advanced with Programming Partners

ROBOTC allows student to use C programming to control their robot. programming in C is a Both languages allow you to create programs that work with driver control, or are completely autonomous.

Events simplify Programming

All the devices connected to the Brain support Event Programming. This simplifies the software by allowing events to trigger software. The traditional programming method involves continuous running loops that check values over and over again, looking for a change. This method created code that is difficult to visualize and learn. Event programming looks like: "when the button is pressed do ...", "when the angle is 90 degrees do ...", "when the motor stops do ...". Instead of constantly polling each device to see if the event has occurred, the VEX IQ system allows each smart module to be instructed to report back if the event occurs. When the event occurs, the smart module tells the brain what occurred. Not only is software simplified, but the Brain does not have to constantly poll each sensor about what is happening, which increases overall system performance.

What makes the VEX IQ Robot Brain so smart?

The Robot Brain uses a Texas Instruments latest Tiva microcontroller running at 80 MHz to perform 100 millions operations per second. The brain has to simultaneously communicate with the controller wirelessly, talk to 12 devices on the Smart Ports, update the LCD and have time left over to run the students programs. It does all this with a custom built operating system developed just for VEX IQ that gives the students programs 98% of the processer's power. The processor knows math so well it can perform a calculation in 0.00000001 seconds. All this technology works together to make a Robot Brain that is simple, flexible and powerful.
