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.
Participants must build and design a robot that will be able to move objects into goals to receive points.
This year there will be two goals, a small goal and a large goal. The large goal is an empty 10x10x12 cm box on it's side in zone D. The small goal will be an empty 10x10x8 box placed on its side in zone C. Both of the goals will be on the outside corner of their zones. The following materials will be placed in zone B:
- 2 yellow legos
- 2 blue legos
- 4 golf balls
- 4 C-cell batteries
- $0.40 in coins
The maximum amount of points you can score is 412. If your robot is completely in zone B at the end of the competition you will receive 5 points, if it is in zone C you will receive 10 points, and if it is on zone D or the goal you will receive 20 points. You will also receive points for the following:
|Item||Quantity||Zone C||Zone D||Small Goal||Large Goal|
|Yellow Lego blocks||2||8||8||24||8|
|Blue Lego blocks||2||8||8||8||24|
|Coins||$0.40 total||value in cents||value in cents||3X value in cents||value in cents|

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 Kits 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.
Some Ways to Pick Up Objects
Another way is a claw with a wrist to give it the highest ability
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) --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) --j) -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)
