Robotic Vacuums Get Torn-down For Design Showdown.

Fictiv runs a 3D printing shop. They have a nice interface and an easy to understand pricing scheme. As community service, or just for fun, they decided to tear-down two robot vacuums and critique their construction while taking really nice pictures.

The first to go is the iRobot 650 model. For anyone who’s ever taken apart an iRobot product, you’ll be happy to know that it’s the same thousand-screws-and-bits-of-plastic ordeal that it always was. However, rather than continue their plague of the worst wire routing imaginable, they’ve switched to a hybrid of awfulness and a clever card edge system to connect the bits and pieces.

The other bot is the Neato XV-11. It has way fewer screws and plastic parts, and they even tear down the laser rangefinder module that’s captured many a hacker’s attention. The wire routing inside the Neato is very well done and nicely terminated in hard-to-confuse JST connectors. Every key failure point on the Neato, aside from the rangefinder, can be replaced without disassembling the whole robot. Interestingly, the wheels on both appear to be nearly identical.

In the end they rate the Neato a better robot, but the iRobot better engineered. Though this prize was given mostly for the cleverness of the card edge connectors.
