Welcome to CTRL PDX! Battle under the Bridge is our second event, and we’re super excited! It's sponsored by Tinkercamp, a makerspace in the St. John's area who's letting us use their awesome space! Spectators and competitors of any skill level are welcome! Bot check-in starts at 9 and brackets will be created at 11. If possible, arrive with your bot ready to pass safety and compete. 

Schedule:

9:00 - 11:00 Check in and safety
10:30 - 11:00 Driver's meeting
11:00 - 1:30  Fights
1:30 - 2:15 Lunch break
2:15 - 5:00 Fights Resume!
5:00 - 6:30 Teardown
6:30 Group Dinner! (optional)

The schedule is designed to have extra time. The event may end early.

Safety: To pass safety, your bot will need to be weighed and demonstrate that it can failsafe. For safety purposes, if a robot’s battery is exposed to its opponent, that robot will lose the fight. In the event of a lipo puncture or fire, we will have a lipo bucket with kitty litter and tongs, as well as someone nearby who can run the bucket out of the building. 

Arena: We have a 4-foot by 4-foot box with an untreated steel floor. There used to be a pit in our arena, but we are permenantly closing it. However, there is still a seam where the metal of the pit meets the metal of the rest of the floor. This seam is the hazard of the arena. If you get stuck on the seam of the pit, you will not get an unstick (usually, getting yourself stuck on the arena would result in an unstick up to once per match as per the sparc rulset). Instead, it will begin a 10 second coutout. We will be using the standard Sparc ruleset for full-class metal antweight, plastic antweight, and fairyweight. The tournament will also use a modified double elimination bracket. If a weight class has less than 6 robots, we will do a round-robin tournament for that weight class.

Fighting Format: The tournament will use a modified double elimination bracket. If a weight class has less than 6 robots, we will do a round-robin tournament for that weight class.Our weight classes and maximum class sizes are:

Fairyweight 12 bots
Full Combat Ant 24 bots
Plastic Ant 24 bots

Money stuff:

Builders will be charged a $20 entry fee per robot. This is to offset the cost of our box, improve builder experience, and to purchase other materials. A portion of this money will also go to the event space. You can pay at the event in cash, or ahead of time via Zelle, Venmo, or here on the RCE website. My venmo is @PabloRiffel and you can send money on zelle with my phone number (503) 300 8381. When paying me online, make sure to tell me which robot you are paying for! If you cannot pay this fee, please let us know and accomodations can be made.

If you want to make an additional donation to the makerspace as well, it would be greatly appreciated. They are letting us use the space for free, and we want to help them stay afloat. We are also giving 25% of the money we make from registration fees to the makerspace. If you are interested in making an additional donation, you can do that here: https://www.tinkercamp.org/donate.php

Prizes: We are working on getting prizes for this event. Likely, we will have prizes for the first and second place finishers of the full combat and plastic antweight categories.

Entry to the building: There are two ways to get inside; through a back door and a short path inside the building to our space, or through the front entrance on Baltimore Ave, up the stairs, and look for room 212 on the map. More information on how to get to the event space can be found on our discord. Signs will also be posted in the building directing competitors and spectators towards the space.
