Portal turret v4.zip is updated and should contain all printed parts needed to build the latest turret. I found Lars' channel along with other videos to be very helpful in coming up with new ideas and using features effectively in Fusion. In the end, it was worth the effort!Īs for videos guides on Fusion 360, I'd recommend Lars Christensen's YouTube channel. This made manipulating and keeping sub-assemblies linked for quick access. I learned quite a bit on this project, such as using embedded components within other components. This was pretty taxing, as there really aren't many boxy shapes in this thing, and it closes up pretty tightly, with no real access for tweaking once put together. This model is what came of those changes. Once that worked out, I went back to the model and made some tweaks to improve appearance and assemblability (is that a word?). Once the entire model was built and I was confident that it would work, and could be built (printed) and assembled, I went ahead and printed out the parts and built a prototype. Why? Because I wanted to use a crank mechanism, that's why! This added some complications, but it also had a benefit once the geometry was determined, operational repeatability would be ensured and the min and max limits were pretty much guaranteed. The wing opening mechanism was a crank and slide mechanism. Printed parts to be as large as possible (not a lot of little pieces) Īfter components (Nano, other chips, servos) were added to the basic shape, they were moved around and positioned as required, and the supporting structures were built to support them inside the shell.A 2.1mm electrical connector for power at the back.Time-of-flight sensor should be invisible as well.MicroSD card had to be accessible in the same manner, and ideally invisible once installed.Arduino Nano had to have connector accessible for updating once fully assembled.All electronics were built in Fusion as components that were inserted and placed where I thought it would make sense. Then it was a matter of extruding them into 3D, then shelling the general shape and making cuts. Using these images as canvases, I started sketching the outlines of the 3 views. The design started from sketches found online. This sensor is nearly invisible from the front once assembled. The lidar sensor (time-of-flight) is on a chip with a rectangular profile. 18 individual expressions and sounds used in this go-round. It is inline with the black infill strip, making it essentially invisible once installed. The sounds are stored on a microSD card, which is accessible from the back side so that sounds may be updated or changed later. With some basic sketches found online, I started modelling and planning. I took some liberties in the design, trying to make it appreciably the same as the one seen in the game, but functional and printable. Use Portal turret sounds and voices from the game. Close up and go to sleep until someone else comes along. If the person is no longer there, run a little scanning search routine. If the person is still there after opening, fire until they drop. Use a crank mechanism with sliders, just because. Open the "wings" if it senses someone in front. The goal here was to make it move in 3 "axes", with spoken sound from the game and LED's to simulate firing. This design uses an Arduino Nano, an MP3 player chip, distance sensor, servos, LEDs and 3D printed parts. For me, this was an exercise of properly modelling the entire assembly in Fusion 360 first, before building anything. This Christmas, I decided to design and build a working Portal turret gun from the game A way to control you Turret gun! Control multiple turrets with a single controller. CARA MIA! - Master Turret Control is here!! -Ĭheck out the Master Turret Control.
