<VUR12>
There is no restriction on commercially available Sensors, External Processors, or Additional Electronics that Robots may use for sensing and processing, except as follows:
• Sensors and External Processors MUST be connected to the V5 Robot Brain via any of the externally accessible ports (i.e., without any modification to the commercially available electronics). A Sensor may be connected to an External Processor which then connects to the V5 Robot Brain.
• Sensors, External Processors, and Additional Electronics CANNOT directly electrically interface with VEX motors and / or solenoid.
• Sensors and Additional Electronics may only receive power from any of the following: Directly from the V5 Robot Brain via any externally accessible port. From an additional lithium ion, lithium iron, or nickel metal hydride battery pack (only one (1) additional battery can be used for Sensor/processing power). This additional battery pack must operate at a maximum of less than 13 volts. Directly from an External Processor
• Only the V5 Battery can power the V5 Brain.
• Sensors, External Processors, and/or Additional Electronics which include a low-powered motor as an integral part of their primary sensing/processing function, such as an External Processor’s cooling fan or a spinning Sensor, are permissible. Standalone motors which serve no additional sensing or processing functionality (e.g., using a commercially-available brushless motor in a drivetrain) are not considered legal Additional Electronics, and would be considered a Violation of <VUR11>.
• Pneumatic solenoids are the only types of solenoids that are permitted as Additional Electronics. Solenoids used for any purpose other than opening and closing a pneumatic valve are considered an actuator and therefore prohibited, per <VUR11>.
• <R28> still applies in VEX U, Teams may not alter or modify electronic parts from the VEX product lines. It is legal to rotate the blocks of the V5 Optical Sensor and V5 Distance Sensor relative to their bases, and to manufacture custom back plates for these sensors.
