Why us

Our team competes in FTC, so hole-grid tolerances, weight targets, and competition deadlines aren't abstract to us. Late parts have cost us matches too, and our process is built around not repeating that.

Every member here is an active competitor. San Diego orders are typically hand-delivered rather than shipped. For anything outside standard plates or printed components, describe the application and we'll determine a fabrication approach.

About us

Crackbotics is operated by three students. Two are members of Runtime Terror in San Diego, and one of All Systems Go in Kentucky. After facing high costs for basic bracket fabrication — and already having the CAD experience and machine access — we began producing parts for other teams.
