It is an RWI. From Jaffrey, NH. The decal became "iRobot" in later models. That means your B21r is rarer than the iRobot models. Only in "merger", but still.... All RWI and iRobot research robots are rare. They have been discontinued for some time.
Thank you for sharing this. I built this B21r. This design was just after the switch from access bus to rFlex. I redesigned the wiring to accomodate the 24v system that replaced the older 48v. Also all the coms changed and new STIs and motor drivers had to be relocated along with cat. 5 cables, rFlex hub and power distribution board. Sick Laser (layer), compass, stereo vision w/pan tilt......and powder coat (available in red (no extra charge) blue, black, and canary yellow). :-)
You mean all this time I could have had a canary yellow B21r?
