FRC 10183 ARC 2026 Robot — "Mr. Peabody"
Competition robot for FRC Team 10183 ARC for the 2026 REBUILT season. A high-throughput shooter bot focused on maximizing FUEL scoring.
Project Overview
Competition robot "Mr. Peabody" for FRC Team 10183 ARC for the 2026 REBUILT season. As a full-time mentor, I guided the team through the design and build process, focusing on a high-throughput shooter strategy.
Role: Full-Time Mentor
Team: FRC Team 10183 ARC
Game: REBUILT (2026)
Robot Name: Mr. Peabody
Tools: Onshape


The Game
REBUILT challenges teams to shoot foam balls (FUEL) into the HUB. Our strategy focused on maximizing FUEL throughput to win matches and achieve ranking points.
Ranking Points:
- WIN — 3 RP
- ENERGIZE — 100 FUEL scored — 1 RP
- SUPERCHARGED — 360 FUEL scored — 1 RP
- TRAVERSAL — 50 climb points — 1 RP
We prioritized FUEL throughput over climbing as more valuable to match wins.
