Origin of the Name
 
White Top: Refers to the iconic white antenna on its head, reminiscent of the tuning knob on an old-fashioned radio, lending it a retro‑tech vibe.
Beep Beep: An onomatopoeic sound that mimics the robot’s electronic voice, echoing its compact and agile form—light, lively, and full of energy when spoken aloud.
 
Introduction
 
It serves as the retro‑style frequency‑tuning specialist within the “Dopamine Robot Squad”: with its rounded square head and articulated joints, it’s easy to 3D‑print into shape, able to stand steadily yet also strike playful poses like waving hello. Its green-and-orange color scheme paired with the white top antenna precisely captures dopamine‑inspired bright, cheerful hues; while its smiling expression and round eyes transform its retro‑tech aesthetic into a soft, endearing charm. Always using its head antenna to “receive happy signals,” it loves swinging its arms alongside Orange Face, making it the squad’s “retro‑energy mascot.”
