Why bother crawling into that tiny sewer tunnel and getting coated in Cthulhu knows what — not to mention possibly getting stuck — when you can roll a robot in there instead? That’s what InspectorBot does. It’s [Dennis]’ entry for The Hackaday Prize and a finalist for our Best Product competition.
InspectorBot is a low-profile rover designed to check out the dark recesses of sewers, crawlspaces, and other icky places where humans either won’t fit or don’t want to go. Armed with a Raspberry Pi computer, it sports a high-definition camera pointed up and a regular webcam pointing forward for navigation. It uses point-to-point WiFi for communication and rocks all-wheel drive controlled by a pair of L293D motor drivers.
This seems like fertile ground for us. Pipe-crawlers, chimney-climbers, crawlspace-slitherers all sound like they’d be helpful, particularly in conjunction with some kind of computer vision that allowed the robot to notice problems even when the operator does not. Right now, [Dennis] has the chassis rolling and most of the current work is focused on software. Both cameras are now working, allowing the InspectorBot to send forward-looking and upward-looking video back to the operator at the same time. This, alone, is a great advancement of the current crop of Raspberry Pi rovers and adds a lot of functionality to an easy-to-build platform.
