Last May, we introduced you to the LawnBott, and it seems that KA Home Robotics is doing well, thank you very much. So well that they have introduced their new LB3500. The device can be programmed via Bluetooth through a compatible cell phone or PDA. Include days and hours and, at the end of its cycle, the Bott will return with its two lithium-ion batteries to its charging station. The 3500 features a higher sensitivity, a blade stop sensor, an on-board alarm, and a 360º bumper shell. Prices range from $3,249.00 to $4,279.00, depending on options.
