A recent entry in MAKE and Cornell University’s Pitch Your Prototype competition, Maker Mike Rigsby has developed a 3D-printed robot capable of, you guessed it, picking weeds! While at first this may sound like yet another mechanism to increase laziness, weeds are actually a serious problem for farmers all around the world, and it’s only getting worse.
