CC-7 “Groundskeeper”
Origin Story
Recovered from a long-sealed broadcast maintenance lab in Tulsa, Oklahoma, CC-7 “Groundskeeper” was first designed as a mobile relay tester for early AM radio transmitters. The lab engineers—pressed for resources—built the unit’s casing from a Cain’s Coffee Co. tin, known for its tight seal and conductive metal finish.
Originally assembled to measure ground resistance and audio signal clarity, the unit’s onboard relay system doubled as a crude broadcast stabilizer, keeping rural transmission lines humming through storms and static. When R3BOTS technicians rediscovered the chassis, it was partially fused to its original test bench—wires intact, speaker plate corroded but functional.
The restoration revealed an elegant simplicity: an analog coil, a Calrad speaker head, and a green-labeled “Machine” solenoid unit—each perfectly tuned to stabilize audio frequencies. Once powered, CC-7 emitted a low hum resembling background radio noise—a steady heartbeat of forgotten frequencies.
Now fully operational, CC-7 serves within the R3BOTS Communications Division, ensuring that every Field Ops signal stays strong and stable, from the factory floor to the far edge of transmission range.
Construction & Components
Torso: Cain’s Coffee Co. 1½ oz steel tin
Head: IDECO junction cap with Calrad PM-1½W speaker relay
Arms: Vintage brass latching terminals with mechanical knuckle joints
Core: Machine-labeled solenoid coil and early broadcast relay wiring
Legs: Dual-threaded rods with compression bolts and grounded stabilizer feet
Base: Standard R3BOTS topographic platform
Capabilities & Function
Signal grounding and frequency balancing
Low-voltage relay testing and field calibration
Environmental noise filtering through analog coil resonance
R3BOTS Recovery Report
Recovered: April 2025 – Tulsa, Oklahoma
Condition: 84% structural integrity, partial oxidation on relay terminals
Restored By: Volt Division – Broadcast Systems Team
Operational Status: Active
Designation: CC-7 “Groundskeeper”
Role: Signal Stabilization and Field Communications
Technical Specifications
Height: 7.25 inches
Torso: Cain’s Coffee Co. 1½ oz Tin
Power Unit: Calrad PM-1½W Speaker Relay / Solenoid Coil
Serial Number: CC7-VLT-403B
Core Function: Ground Resistance Testing / Frequency Stabilization
Personality Profile
Steady – Grounded – Loyal
CC-7 stands firm and unshaken, humming quietly even when others lose signal—a reliable sentinel of calm amid the static.
Repurpose. Rebuild. Reinvent.
