Operator Interface

The following information is outdated, but is retained for historical reasons

The Operator Interface, or OI was the name of the unit of the control system that collects input controlled by the human operator(s) and transmits it to the Robot Controller.

Prior to the 2010 season, this was a special control box. After that, a laptop computer was used to communicate with the robot and it is now referred to as the Driver Station.

In the past, the OI communicated with the RC using either a radio modem or tethered connection. The OI inputs data from 4 ports. It also transmitted data out of the dashboard port.

The control system uses a team number identification system to ensure proper communication during matches. In the past, teams set their team number into the OI using DIP switches. As of 2010, team numbers are set via inputting the number into the operator interface computer.

In general, the OI stays relatively the same from year to year. However, typically the Robot Controller and Operator Interface of the same year must be used together. To learn more about the different versions, see their respective pages.
