Linux-based underwater robot goes faster, longer

The OpenROV project began shipping version 2.5 of its Linux-based, $849 underwater robot kit. The open source OpenROV 2.5 design advances to a 1GHz BeagleBone Black SBC, scraps the earlier BeagleBone cape in favor of a faster Arduino-compatible controller board design, and boasts improvements to buoyancy, durability, speed, and battery life.
