Portal-ish Automated Turret


[RazorConcepts] has built this cool automated turret. It is a home made frame with an airsoft gun, a Roboduino development board, a rangefinder, camera, and some servos.  They programmed it to keep up constant random banter from the game as well as respond appropriately do different inputs. For example, it complains when you pick it up or knock it over as well as announcing if it has acquired a target. The range finder is mounted on its own servo which constantly sweeps back and forth, so the turret itself mainly sits still. You can see that the tracking is not so great in the video. [RazorConcepts] notes in the instructable that this is because the main focus was just to make it for “show”. We’ve seen our fair share of turrets before. We think he did a good job, but if it is just for show, maybe spend some more time on a nice body and smoother motion.

4 Or More Servos On An Arduino


The latest version of the Arduino software allows you to use more than two servos at a time. Curious Inventor has posted a demo showing how to run 4 servos from a keyboard input. The code should also work just fine on Arduino clones, like the Roboduino pictured above. They point out that if you are running version 12 of the software, some manual additions will be necessary.
