Electronics is a part of both the building and programming aspects of robotics. This page will walk you through each electronic, from sensors to batteries. It will also show you through how to configure electronics when coding.
The brain is the essential part of the robot that makes everything work. It has 3 main parts on it, Drive, Programs, and Electronics, which will be explained more in depth later.
The Controller is connected to the brain through either a wire or smart radio. The buttons can be programmed to serve different functions when driving.
The VEX IQ Smart Motor is used to rotate shafts. It has a set speed of 120 RPM, but that can be changed through gear ratios.
The battery is the part that makes the brain turn on. It is charged using a USBC cable, and snaps into the back of the brain.
The battery charger is the way to charge Generation 1 Batteries and are an alternative way to charge Generation 2 Batteries.
Smart Cables allow you to connect devices, such as motors and sensors, to the brain so that the electronics can be controlled.
Sensors
The Distance Sensor can tell if an object is in its view and calculate the relative size, distance, and velocity of a game element.
The Optical Sensor can identify if an object is in front of it. It can also provide the colors and numerical hue values of game elements, and detect their brightness level while also emitting light.
The Bumper Switch has an imput of 0 and 1 that allows you to tell if the sensor has been activated or deactivated.
The Touch LED can detect capacitative touch while also emitting different colored lights.
The Gyro Sensor allows you to know the robot's speed and rotation.
The Distance Sensor can detect whether or not something is in its field of view and can calculate the distance between it and an object.
The Color Sensor can identify color, hue value, brightness, proximity, and grayscale value through reflected light.
When utilizing VEX IQ's electronics, it is a great starting point to watch videos and read websites (such as the one you are currently reading) to understand how your electronic works. Doing so will eliminate most confusion and allow you to better incorporate your electronic into your robot build.
However, if you are facing issues, there are multiple ways to work around them.
For one, many teams learn by trial and error, which can be done by controlled experimentation. With controlled experimentation, testing is done to determine the cause of the problem by removing factors one at a time.
If the solution above does not work, you can also search for answers in other resources, such as the ones we have listed on the bottom of the page.
Finally, you can ask your upper-classmen who have more experience in when dealing with electronics.
Dropping your electronics can cause much harm to its hardware, causing malfunctions and confusion over if the problem stems from the build of your robot or the electronic components.
If you do drop something, test it out to see if any damage was done, and tell your coach.
Do not be afraid to take risks. One facet of robotics that is quite appealing is the leinancy towards adaptation and implementation. There are many different ways electronics can be used and implemented in your robot and different ways to optimize them, such as programming. Learn about programming here!
You can learn much more through controlled trial and error than from just reading articles on the internet.
These are other websites and sources that have great, accurate information as well as tips for configuring and utlizing electronics in VEX IQ.
