The R-Gator is an unmanned all-terrain vehicle, developed by John Deere and iRobot, that can be programmed to perform a range of military tasks. Based on Deere's M-Gator military ATV, the R-Gator employs robotics technology developed by iRobot (think Roomba). It can relay real-time video, sounds and sensor readings; shuttle supplies using GPS waypoints; follow soldiers' footsteps, carrying gear; or transport hazardous materials. It can also say "Danger, Will Robinson" in seventeen languages and cook a mean MRE souffl .
