This guitar bot is part of the Legue of Electronic Musical Urban Robots, or LEMUR. As you can see in the video, it has 4 strings, each mounted on it’s own unit. The pitch is controlled by a sliding bridge, while the strings are plucked by a series of picks mounted to motor. The sliding bridge is quite fast, being able to shift 2 whole octaves in a quarter of a second. The final effect is quite nice, we would listen even if we weren’t watching a robot work. This is the kind of thing we should expect to see at the Guthman Musical Instrument Competition.
