[EV3] Mindstorms Star Wars AT-AT
The_Icestorm posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Standing 58cm tall and 59cm long, this AT-AT from Star Wars is probably my largest robot to date. It is controlled by an EV3 p-brick, and is capable of walking, turning its neck, and shooting balls from a twin-ball launcher located inside its head. Here is a list of the functions of the robot: - Walking: 2 EV3 large motors - Neck turning: 1 EV3 medium motor - Shooting: 1 NXT motor Also includes an EV3 IR sensor for use with the EV3 IR remote. After getting the BWE, I had a plentiful supply of grey beams and panels, which I used in the aesthetics of the model. The head design was the most tricky part of the build. I needed it to look good, while at the same time have enough space for the twin-ball shooter with magazines. However, I'm happy with the end result, as it looks quite accurate to the actual thing. With the amount of pieces I had, I was also able to achieve a (almost) full body cover, which although adds to the weight of the robot, looks really nice. There are also two flaps on top of the head that can be lifted up to access the ball magazines. Walking was especially tricky to achieve in this model, as it was so top heavy. Rubber bands had to be used to help pull in the legs when they bore the load of the robot, otherwise the motors would not have enough torque. All legs are controlled simultaneously by the two motors, so the robot theoretically can't turn. However, I doubt the robot could turn even if the two sides could be controlled independently, since it is so top heavy. The EV3 brick can be accessed through opening of the panels on the side of the body. This was the easiest way to access the electronics while keeping a full-body cover (The real AT-AT in the movies also had opening side body panels). Here is a video of the AT-AT walking, turning its neck, and shooting.

Hey folks This is an animation that I created with my friend Alex to represent our duke of Edinburgh walk, we spent around 140hrs on making this film over the course of 7 weeks, using a mixture of Lego, plasticine and model grass and trees. Weve hidden over 50 different references to some of our favourite movie or tv shows throughout the movie. Hope you enjoy the movie
