These bots have moved through a few company splits / mergers / acquisitions, but for a while these were made by iRobot (along with the mentioned Packbot). When I was working there, these used to be a fun one to bring to schools we were giving talks at, because they could take a serious beating. Great way to get kids attention at the start of a talk by just lobbing one of these across the room / out into the hallway and let the kids try driving it. Glad to see they are getting some use in helping people out!
