Bot Rules

The rules for robot construction follow these SPARC guidelines, specifically, for the 1 lb plastic class.

Here are the most important ones to remember:

• Frames, weapons and other custom parts may only be made from PLA, PLA+, PET, PETG, ABS, or ASA and must be FDM 3D printed

• COTS parts may not be used outside of their typically accepted function. For example, screws may not be used to enhance the power of the weapon

• RF jammers, liquid, fuel, or entanglement devices are prohibited

• If the transmitter loses connection, the bot must power down movement and weapon motors/servos immediately

• All robots must be able to be fully deactivated, which includes power to drive and weaponry, in under 60 seconds by a manual disconnect

Match Rules/Procedures

The SPARC rules for a double-elimination style bracket will be followed for this event. The most important points are listed below.

Match rules:

• 3 minute match time

• 1 unstick for any reason

• If a battery becomes exposed, that robot will immediately lose

• Pinning is limited to 5 seconds, counted down by referee. After 5 seconds, you must release

• A team can tap out at any time

• A bot has at least 20 minutes between matches

• Once a bot is called to the arena, they have 5 minutes

Check-in procedure:

• Weigh in with all electronics/batteries

• Demonstrate weapon and movement

• Demonstrate that a loss of signal powers down the robot motors

• Demonstrate that killswitch disconnects power from electronics

Arena

• The arena is approximately 6ft x 6ft

• The floor is made of plywood

• Metal kickplates will cover the bottom portion of the 4 walls

• No hazards (trapdoors, shelves, arena weapons, etc.)

Schedule

Facilities

Fabrication Lab

This tournament will be hosted at the Watson Engineering Fabrication Laboratory, and there will be some equipment available for teams to use. However, please bring your own tools/equipment, as this will not be enough for all teams to use at once.

Expected equipment available for the tournament:

• 4 soldering irons

• Hex keys, pliers, side cutters, screwdrivers

• Extension cords that extend from the ceiling cover all areas of the fabrication lab

• Tables

• A large table with soldering mats, seats 16

• 11 regular tables with 4 chairs at each

Food

The university food court is located directly adjacent to the fabrication laboratory. Check it out here, under “Marketplace at the Union”.

The food court takes card only (ATMs are available).

Parking

Here is a map of the available parking spots. Any lot that isn’t a paystation lot will be free for the weekend. Lot Q1 is directly across the fabrication lab and will be the most convenient to park at.
