    Focused light sources - Not allowed

    Originally posted by FTC3965
    Are LIDAR Sensors allowed?
    They do use focused emitted light; but, so do the reflective light sensors.
    I see some teams used them last year and were allowed if there power level was below a certain level
    A: No, per <R06>a. LIDAR is both a laser and a focused/directed light source and is thus not allowed.

    Manufactured sensors - Allowed; Custom sensors - Not allowed

    Are there provisions in the rules that allow us to generate custom sensors as was indicated when the new control system was being released? If so, what rule allows the use of momentary switches as limit switches and touch sensors? Would the same be used for potentiometers as rotational sensors?
    A: No, per <RE06>b. custom sensors are not allowed; compatible sensors include manufactured sensors that are connected directly to the Core Device Interface Module or to the Core Legacy Module either directly or through a HiTechnic NTX1060 multiplexor.

    Simple manufactured devices may be considered sensors as long as they are compatible with the Core Device Interface Module; thus a simple switch is an allowed sensor. Note that per <RE06>d. you may not add any other electronics to the switch. If required, per <RE05>g. “sensor wires and their connectors may be extended, modified, custom made, or COTS” to connect to the Core Device Interface Module.

    Additional electronics - Not allowed

    1. Will teams be allowed to use Arduinos / prototyping boards this year?
    1b. If they are allowed, are there restrictions as to their use (interfacing with a sensor and reporting results back to the CDIM, or only decorative use such as quickly cycling LEDs to save power instead of just hooking all the LEDs directly to the battery and/or displaying an image on an LED matrix, which also requires rapid LED cycling).

    The ability to incorporate Electrical Engineering more into the curriculum would be fantastic. It's understood the Core Device Interface Module can perform many of these functions, but for something which requires rapid updates, it would be highly preferable to offload this away from the phone and the devices running the robot.

    Does <RE06> exclude supplementary controller boards (ex: Arduino) and/or Custom/DIY Sensors?

    Would a digital volt meter be allowed on the robot? (example: http://www.powerwerx.com/batteries-c...ter-12vdc.html )
    A: No, per <RE06>d. “Other electronics are not allowed.” The only allowed additional electronics by <RE06> are light sources (see also <RE03>g.), manufactured sensors and the HiTechnic NXT1060 multiplexor, and video recording devices (see also <RE03>f.); in addition, manufactured sensors must connect directly to the Core Device Interface Module or to the Core Legacy Module either directly or through a HiTechnic NTX1060 multiplexor and may not connect directly to robot power or to USB. Note that this rule also precludes the use of Legacy prototype boards, microcontroller boards, and custom sensors.

    Communicating with additional electronics is likely to require drivers or other software support which is not available or which may not be compatible with the Robot Controller software used in this year's game. Although not allowed for this year's game, GDC will evaluate software and driver availability and compatibility to determine what additional electronics can be supported in future games.
