Nerf FBA_B8072 N-Strike Elite TerraScout

Product Information

This metric was our favorite. We took our panel of expert professional product testers, provided them eye protection, set the blasters out in front of them, said, "Have at it," and watched everyone smile from ear to ear. At the end of a full-blown, no holds barred foam projectile battle extravaganza, we simply asked everyone which models were their favorites. A few models easily stood out.

The first step in programming our system was to set up the system to capture a picture and detect where the faces are inside of the image. To do this, we used OpenCV, a popular open source library for computer vision which has many pre-trained classifiers for object detection, and referenced an example using face detection from TheCodacus.com (referenced below). We chose to use the Haar cascade classifier for face detection, using the provided haarcascade_frontalface_default.xml file from OpenCV. It only works on gray scale images, so after capturing each image we convert them to grayscale with OpenCV. Then we ran the classifier which returned the location of a bounding box around each face. During testing, we displayed the image with this box on our screen and found that this classifier worked reasonably well to detect faces when the person is looking directly into the camera. Facial Recognition - Collecting imagesdefine disablePlateDelay 5000 // how long to disable sentry when plate is pressed (in milliseconds) We spent dozens of hours researching Nerf blasters before we bought the 9 best models on the market today for a head-to-head Nerf weapon battle royale. We carefully inspected each product for the subtleties and differences in features that set it apart from the others. We considered how hard the manual powered Nerf blasters are to set as well as the size and price of the batteries for the electric models. We even measured the maximum distance each blaster was able to shoot its projectile. Most importantly, we judged how much fun each model was to use. Read below to see the results of our comprehensive Nerf blaster review. I originally wanted to use the base plate of the chair, but noticed that it was quite shabby. So after cutting off the cushion I replaced it with a 20x20x1.5 cm plywood plate, as shown in the pictures. During the two months of evenings and weekends he spent working on the project over the summer, several design changes were made. “The biggest disappointment was that the huge chunky motors I had didn’t have enough torque to turn the bot successfully. Getting the right motors is an area where I am definitely still learning and it’s a critical factor to get right in building a successful bot.”

These, along with the robot’s drive motors, require a lot of battery power.The gun on the Terrascout is a rapid-firing, motorized Nerf gun similar in design to the Rapidstrike, but shorter and built on a motorized mount rather than a gun grip. It accepts Nerf N-Strike magazines through a slot on its right side, and includes an 18-shot magazine and darts. The top of the gun holds a large handle with an N-Strike accessory rail on top, so you can both easily carry the tank and mount a light or other Nerf rail accessory on it. A second accessory rail sits under the barrel.

I would love to build this, but its missing some directions, like webcam? can you post the full wiring setup please? In my opinion, a 5 kg spring works best (the original one is a two kilo spring). I tried a 7 kilo spring in one, and although it was strong, it resulted in a lot of mis-firing. Now Nerf has created a new version of the toy that means you can remotely target someone - and not even have to be in the same room as them (via Gizmodo ). To generate the PWM signal, we need to specify a frequency and duty cycle. The servo expects 20 ms ‘off’ time, so the equations for the frequency and duty cycle are given below, where ‘pulse’ is ‘on’ time. Pulses of 1.5ms turn the motor to 90 degrees; shorter pulses move the servo to 0 degrees and longer pulses move towards 180 degrees. Pulse length is set based on how far off-center the target currently is from the reference point of the aiming system. The camera is mounted on the Nerf gun, and its center is aligned with the barrel. Therefore, we set the change in pulse width to be the difference between the current x and y coordinates of the center of the target face and (160, 120), the center of the frame. We limited the minimum and maximum pulse lengths for each servo to the range we found it could smoothly travel. We also limited the maximum change in pulse width in one time step so that the servo movement would not be too jerky. Glue the sides to the bottom plate of the box, as shown in the first picture. The piece in the front was supposed to hold the webcam. But after using the gun for the first time, I noticed that even though the base is really sturdy it moves a bit when the gun stops, which results in false detections. So I just decided to place the camera on the floor in front of the gun until I'll be able to find the time to build a tripod for the camera.Either unscrew the mechanism, or use pliers to place the wire underneath it, as shown in the third picture. Now all that is left to do is to secure the wires with hot glue, as shown in the fourth picture of this step. I simply connected the two wires; But you can also add a switch, to also enable firing by pulling the trigger. state = 0 elif ( not ( 1 in targets) and ( 1 in civilians) and x >cols_left[ 0] and x rows_up[ 0] and y

User Interface

As the system is based upon computer vision, we needed a reliable camera that could be attached to the barrel of the gun. We first investigated the 8 Megapixel Pi camera. After plugging and unplugging the camera multiple times during testing, it stopped connecting to the system. As we had access to a Logitech C920 HD Pro Webcam, we decided to integrate it into our system instead of the Pi camera. This camera interfaces over USB to the Raspberry Pi so it was easy to wire and mount to the system since we did not need a long ribbon cable. One problem we ran into when using the USB camera is that the OpenCV capture function has an internal 5 frame buffer. This meant that when we tried to get a image, it was out of date by the time we accessed it. The solution we came up with to get one current frame is to read 5 frames, throwing away the first 4 and only keeping the 5th frame. Another issue we encountered with the camera was that it would occasionally not turn on while our program was running, especially when it had been idle for some time; we did not come up with a permanent solution to this, however unplugging and replugging the camera and restarting the program usually worked. Electrical System In this instructable, I will show you how to modify a Nerf Vulcan to automatically aim and fire at targets. As an added bonus, this gun won't fire at anyone wearing a shirt with the instructables robot on it. I had this project in mind for a long time and finally managed to find the time to bring it to life.
