Go to Post I don't know how much of a safety factor chain manufacturers build into these ratings. I've got empirical evidence to demonstrate that it's not 5, however. - Tristan Lall [more]

If I'm not mistaken, the FRC robot controllers come equipped with a copy of the default code (same code available on IFI's site). The percentage of teams who choose not to use the default code in FRC is probably much higher than FTC though.

Re: [FTC]: FTC Software Requirements

Regarding re-entry into autonomous mode - low battery voltage can cause th e robot to re-enter autonomous mode.
1) Motors pull enough current to reduce the voltage below that required to run the processor.
2) Processor stops running
3) Motors turn off
4) Voltage goes up and processor reboots (into autonomous as if match were starting again)
5) Cycle repeats

Re: [FTC]: FTC Software Requirements

At the Virginia FTC Tournament our robots were initially failed at software inspection (we were ultimately allowed to compete, but only after a match was missed by one of our teams)
Our robots (teams 226 and 369) programmed with MPLAB were using the correct version of master code and software libraries for FTC competitions. The software had performed flawlessly on a regulation competition field at the Battlefield scrimmage two weeks earlier. After reviewing the documentation since returning home it is clear that our robots were being inspected according to the criteria specified on page 7 of “Appendix 2 – Programming Information” available from the FIRST web site. The information on page 7 applies only to robots programmed using EasyC. If you look at the table of contents; pages 3-7 apply to EasyC V 2, page 8 applies to EasyC Pro, and page 9 to MPLAB. The first repeat of the master code version, the message “Autonomous(20)”, the repeat of the master code version again, and the message “OperatorControl(254)” shown on page 7 are only displayed when running a robot programmed with EasyC. These were the messages which I was told were not correctly appearing when our robot was powered up. When using MPLAB these messages do not appear. In addition, Interrupt Jumper 6 must be INSTALLED to enable autonomous when using MPLAB. With EasyC installing Interrrupt Jumper 6 disables autonomous. The software inspection procedure needs to be fixed.
