An 81 year old Queensland, Australia man committed suicide with the help of a "robot", or at least an automated machine designed to repeatedly fire a .22 semi-automatic pistol. He set up his robotic device in the driveway in front of his house at 7am in sight of nearby workers. After loading the gun with four bullets he activated the machine. Workers attracted by the shots called police. Only limited details were available about the man's homebrew machine. It's said to have been built from radio-controlled model parts. He based his design on websites that described similar machines built to fire toy guns. Remote-controlled airsoft guns are common. There's even an Instructables step-by-step on building your own RC gun. If you need a more mobile deathbot, try the Vex Air Soft Gun Station (or maybe the Vex Flame Thrower). Death by the indirect action of machines is rare but non unknown. A 2007 Michigan suicide used a self-activated guillotine. Several people have used the two assisted suicide machines created by Jack Kevorkian, the Thanatron and the Mercitron. It's probably a stretch calling any of these machines robots but it makes for a good headline. Fox News even sensationalized it a bit more, titling their story, Man Gunned Down in Driveway by Killer Robot.
