Build the arena

A 15- and 30-pound combat robotics arena for the region

Placer Robotics is developing a portable, full-containment arena built for two classes: the California 15-pound State Championships we already host under NRL rules, and the 30-pound class the region does not yet have a venue for.

It is designed for youth and college teams, school demonstrations, and regional events across Placer County and Greater Sacramento.

Design under independent engineering and fabrication review. Not released for fabrication.

Regional growth

The next step in a system that is already working

In 2018, the region had no local youth combat competitions. Placer Robotics has since built 4 combat arenas, developed a season of local competition, and become the host of the California 15-pound State Championships. This arena gives that championship a purpose-built home and adds the 30-pound class, which the region has no venue for today.

The arena is planned as shared regional infrastructure, not equipment for one permanent venue. It must travel, store efficiently, set up with a trained crew, and use parts that local shops can repair or replace.

Built for teams, schools, events, and technical education

Youth combat teamsA regional path from smaller combat classes to the 15-pound championship stage and on to advanced 30-pound design, fabrication, repair, and competition.

College teamsA suitable regional arena for 15- and 30-pound competition, demonstrations, and student engineering work.

Schools and technical programsA visible platform for mechanical design, manufacturing, electronics, controls, and event operations.

Regional events and industryA portable centerpiece for public events, workforce demonstrations, sponsor engagement, and community competition.

The project is informed by Sierra College Mechatronics, regional combat robotics experience, and local fabrication resources. Exact review, fabrication, and student roles remain subject to confirmation.

Four ways to move the build forward

Fund the buildGive to the arena campaign. Cash gifts and in-kind commitments are reported separately.

Sponsor the arenaSupport the project through title, presenting, material, fabrication, or community-partner recognition.

Contribute materials or servicesThe project needs polycarbonate, steel, cutting, welding, coatings, hardware, transportation, storage, and event support.

Provide technical reviewQualified engineers, fabricators, arena operators, and experienced combat robotics organizers can review the design, fabrication plan, handling plan, and operating procedures.

Frequently asked questions

Is the arena already built?: No. The project is in design development, and the current concepts are under independent engineering and fabrication review.
Which weight classes is the arena for?: Both. It is sized for the California 15-pound State Championships, which Placer Robotics already hosts under NRL rules, and for the 30-pound class, which gives youth and college teams a regional path to more advanced design, manufacturing, repair, and competition.
Will the arena replace the current smaller arenas?: No. Placer Robotics has built four smaller combat arenas in two years, and those keep serving the ant and plastic-ant classes. This arena gives the 15-pound championships a purpose-built home and adds 30-pound capability.
Can a company contribute materials or shop work?: Yes. The project can use qualified support for polycarbonate, steel, cutting, welding, coatings, hardware, transportation, storage, and engineering review.
Can we reserve the arena for an event now?: Not yet. The arena is not built, and no public-use date is confirmed.

Help build the next piece of regional robotics infrastructure

Placer Robotics has already built the teams, events, volunteer network, and smaller arenas. The 30-pound arena is the next shared tool. Help us fund it, fabricate it, review it, transport it, and bring it to the region.
