Servo motors are a type of motor which integrates positional feedback into the motor in order to allow a single motor to perform repeatable, controllable movement, taking position as the input signal. WPILib provides the capability to control servos which match the common hobby input specification (PWM signal, 1.0ms-2.0ms pulse width)

The Robot Preferences class is used to store values in the flash memory on the roboRIO. The values might be for remembering preferences on the robot such as calibration settings for potentiometers, PID values, etc. that you would like to change without having to rebuild the program. The values can be viewed on the SmartDashboard and read and written by the robot program.

The 2015 convention for using the Axis camera uses mDNS with the camera name set to axis-camera.local At home this works fine as there is only one camera on the network. At official events, this works fine as each team is on their own VLAN and therefore doesn't have visibility to another team's camera. At an offseason using a single network, this will cause an issue where all teams will connect to whichever team's camera "wins" and becomes "axis-camera", the other cameras will see that the name is taken and use an alternative name. This article describes how to modify the Dashboard and/or robot code to use a different mDNS name to separate the camera streams.

The roboRIO Analog to Digital module has a number of features not available on simpler controllers. It will automatically sample the analog channels in a round robin fashion, providing a combined sample rate of 500 ks/s (500,000 samples / second). These channels can be optionally oversampled and averaged to provide the value that is used by the program. There are raw integer and floating point voltage outputs available in addition to the averaged values. The diagram below outlines this process.
