![]() ![]() Gioiosa’s replica turret is an impressive real-life homage to a game that he is passionate about, and for a first time 3D printing/ Arduino project it’s really a huge success. An array of PIR sensors could potentially be integrated instead, to map movement around the turret in more than one dimension. This ultrasonic motion sensor was capable of detecting how close things are to it, but is limited to 30 degrees of vision and can only detect proximity in a straight line.

He decided that the best way to track motion would be with a HC-SR04 proximity sensor. ![]() The 3D print job was relatively simple but time-consuming, with a number of different parts to be printed and then some extensive post-processing tasks. recent free obtain motion pictures are principally in theatre print. Four MG996R Digital Metal Gear Servos were used to get the turret to move as he wanted it to, and he took a speaker from a bluetooth shower radio. com reaches roughly 937 users per day and delivers about. Most of the designs were done using the Solidworks software program, which Gioiosa had free access to through his course. Gioiosa’s three main requirements for the project were that the turret’s arms would be able to pop out, it would be able to speak, and it would be able to make use of a proximity sensor.

Sorry for bad image quality, Xbox won’t allow me to upload any more screenshots lmao. Shoutout to this random Sentry Turret for choosing not to kill me. I modelled up the pod body, using reference images and sculpt mode, This was then shelled and the doors cut from them.The only requirements for the maker assignment he was given by the college were that it had to make use of 3D printing technology and Arduino hardware. Arduino was perfect for the sentry turret project as using the Arduino hardware would enable the turret to incorporate similar functionality to the original in-game version, rather than just being a 3D printed prop. sorry for not including the cores, I kinda did this in a hurry. Stage one was working out if the doors would be physically possible, as they clip inside the model in the game.Ĭan the doors still sit flush and extend out as they do in game? This also means I can have fine step control over the motors for the other axis. I originally thought on high RPM motors with leadscrews to extend the doors to the matched speed in the game, However when testing max speed on a Nema17 Stepper, It was fast enough. The main frame will be 2020 extrusions and panels will bolt onto this, which allows for modularity and ease of access for wiring and repairs. Fortunately there’s tons of interesting stuff around the Portal’s turret in the internet. Before I dig into the finer points of 3D printing this mechanical creature on 3 very wiry legs, let’s have some fun. I have a bunch of 2020 extrusion and other 3D printer spare parts, and decided on utilising these. We have the models - Portal turret for Solidworks and same turret for AutoCAD. After the design had progressed enough, the design of the frame was printed on paper, glued on the plywood, and cut out using a jigsaw. ![]() In the case of the Turret, it is an egg shaped piece of plywood, 18mm thick. I measured it all up and decided on 1.4m (Without the aerial). A part that all other parts can connect to. So I started to casually take reference images in game and even used Handrail building regulations to refer to a real world scale. “Hmm, I wonder if that could work”, It’s quite big which means there should be enough space for mechanics etc… Current Progress Showcased at Advanced Engineering 2019 Tradeshowįull Size 1.4M Tall animatronic Portal TurretĪfter completing the Portal Gun project in May2018Īnd how pleased I was with the final outcome, I started to think about my next project. ![]()
