[Vincent] plays around with remote manage tanks, as well as even though his present design is a WWII-era armor piece, he’d still like contemporary accoutrements such as a terminate manage computer as well as laser sighting for his primary gun. His most current job did just that (French, Google translation) with the assist of an Arduino, a few adjustments to the receiver, as well as an IR rangefinder.
The stock RC storage tank includes servos to step the turret as well as the requisite electronics to terminate an Airsoft gun. The precision of the mechanical motions inside the turret weren’t extremely precise, though, so [Vincent] had to gear down the servos to turn big motions into minor adjustments. After that, he installed an IR rangefinder as well as laser diode onto the barrel that enabled the gun to sight a target as well as checked out its distance.
After some experimentation with the rangefinder as well as laser, [Vincent] plotted data from firing a few BBs at a whole lot of distances as well as targets. The graph came out relatively linear, as well as after plugging this into a graphing calculator, he was able to discover an equation that took into account the distance as well as angle so the Arduino-powered terminate manage computer would hit its mark.
The accuracy of the gun is extremely impressive, all things considered. [Vincent] is able to accurately terminate BBs downrange as well as hit an 8×12 cm target at five meters. You can inspect out that action below.
