Some initiatives we cowl are easy, whereas some descend into the kind of obsessive, rabbit-hole-digging-into-wonderland insanity that hackers in all places will acknowledge. That’s exactly the place [Excessive Overload] has gone with the AimBot V3, a target-tracking BB-gun that makes use of three cameras, two industrial servos, and an indeterminate quantity of computing energy to trace objects and hearth as much as 40 BB gun pellets a second at them.
The entire undertaking is overkill, made from CNC-machined steel, epoxy-cast gears, and a chain-driven pan-tilt system that appears like it will take off a finger or two earlier than you even get to the shooty bit. That’s pushed by enter from the three cameras: a wide-angle one which finds the goal and a stereo pair that zooms in on the goal and determines the space from the gun, utilizing a number of hundred frames per second of video. That is then used to purpose the BB gun inventory, a Polarstar mechanism that fires as much as 40 pellets a second. That’s fed by a custom-made feeder that makes use of spring wire.
The entire thing comes collectively to kind an enormous gun that may routinely monitor the goal. It even makes use of movement monitoring to discern between a static object like an individual and a dart fired by a toy gun, selecting the dart out of the air no less than a number of the time.
The draw back is that it solely works on targets with a retroreflective patch: it features a 15 watt IR LED on the entrance of the gun. The digicam detects the intense reflection and makes use of it to trace the goal, so all you must do to keep away from this explicit Terminator is be sure to aren’t carrying something too shiny.
