Four articulated robot arms line a scrolling conveyor belt, each independently reaching out to grab colored parts as they pass, then swinging them inward to build up a growing circular product on the central platform. This mirrors real factory-floor automation, where fixed robotic manipulators perform pick-and-place cycles in a continuous loop: reach, grip, carry, release, repeat, without any central coordinator telling them what to do at each instant. Each robot runs on its own phase-shifted timing cycle, so watch for the staggered rhythm as arms reach, lift, and place parts slightly out of sync with their neighbors. As parts accumulate on the product base they stack outward in rings and upward in layers, visually tallying the swarm's cumulative output over time.
