[Akira] looks to increase his urban canvas by tagging poles which some custom hardware. If you’re looking to add some art to a lamp post, height becomes a problem. That’s where this little guy comes in. The remote-controlled pole climber includes a marker that leaves a trail as the device climbs and descends.
The rig clamps around a pole, with omnidirectional bearings on three sides of the four-sided frame. That last side is occupied by a rubber wheel mounted at a bit of an angle. When the motor turns the angle of the wheel causes the jig to rotate around the pole and climb at the same time. To come back down the motor is simply reversed. XBee modules are used to make a rudimentary wireless control with a button for up and another for down. It looks like the marker is also mounted on a servo but we didn’t see a way to control when it is actually touching the pole. Perhaps you can figure it out by studying the clip after the jump.
