Robo-Cross

Robo-Cross is an event in which participants must design and build a robot capable of performing various tasks. This robot must meet certain parameters, such as size, method of control, electricity used, and overall safety.

Getting Started

Build a board/playing field.

There are many ways to get started, but the easiest way is with a mechanical construction set or a kit.


 * The VEX Robotics Design System is a good, but somewhat pricey set to begin with. It will yield decent robots, but expect to pay for marked up proprietary components.


 * Lynxmotion is a good place to find parts and well-designed kits for robot chasses. There are also complete sets of construction blocks (based on servo brackets) available.

Tournament Student Self Check List
Before turning in your robot for impoundment, please check the following qualification parameters for your robot. Robots that do not meet these parameters may compete but will be ranked after those robots that do. Additionally, if a RC robot is operating on a band other then 27, 49, or 75 Mhz it is not in compliance with FCC regulations and may not compete in the Robo Cross event.

-No more than one robot may be used by a competing team. (Rule: 1-a) -Control system must be powered by a battery, which is not to exceed 9.6 volts. (Rule: 1-c) -Robot must fit into a 30cm cube prior to the start of competition. (Rule: 1-d) -Robot is powered by commercial batteries. (Rule: 1-e)(Its really the only way to determine your voltage, and homemade batteries are just too dangerous) -Batteries do not exceed 9.6 volts. (Rule: 1-e) -Voltage output on robot does not exceed 9.6 volts. (Rule: 1-f) -Only electric circuits � no hydraulics, pneumatics, or fluidics. (Rule: 1-h) -If a transmitter is used, it is to be powered by a commercial battery with an output not to exceed 9.6 volts. (Rule: 1-i) (That mean no laptops or 8 AA 1.5v batteries, one alternative can be 8 1.2 rechargeable AA batteries) -Robots must have a legible I.D. with letters 1� tall or larger. (Rule: 1-j)
 * RC models are in approved frequency range � 75Mhz, 49Mhz, or 27Mhz. (Rule: 1-k) (It's actually illegal for land vehicles to operate at any other frequencies. Do not buy Aircraft transmitters; however, some manufactures sell the same transmitters for Land use.)

Bring to competition:
 * A copy of the rules
 * Any clarifications from soinc.org, in case the judges aren't aware of the clarifications. This is especially important at invitationals, when judges are less likely to have read all the clarifications.
 * Duct tape
 * Scissors and/or knife (box cutters, etc)
 * Soldering iron and solder, because sometimes the judges will let you repair wiring on the spot (but they are not supposed to)
