An automatic Nerf Turret.
This uses Pi4J to control GPIO on the Pi, see http://pi4j.com/index.html for details, or the javadoc at http://pi4j.com/apidocs/index.html for info on how you program it.
Uses Restlet as a lightweight web server, see https://restlet.com/open-source/ for details, or the javadoc at https://restlet.com/open-source/documentation/user-guide/2.3 for info on how to use it.
- Added Bootstrap To CSS Files To Make Things Look Nicer W.I.P
- Added
<center>Tags To The Joystick - Added Background To Joystick
- The turret now scans back and forth in auto mode.
- Added a trigger servo and a corresponding button to
control.html. - Pi now connects to our
BlinkyBotNetnetwork for control over wifi.
- Got the servos working using the Hummingbird robotics kit. The external power source was necessary for them to work.
- The Servos now contain the Hummingbird robot and issue movement commands to it via the
setServoPosition(...)call. - Modified the control sliders to use values from 0 to 255 to match the range of the servos, and made the tilt one larger so it's easier to control.
- Added hummingbird Windows and hummingbird Raspberry Pi libraries.
- The Hummingbird won't run in headless mode for some reason, it is throwing an AWT X11 window exception, but you can fire up the Pi and run it through it's UI. In the end we won't want to run this through the UI.
- Since The Reslet Web Server Doesnt Support PHP files i uploaded them to my domain
nmsnerfturret.tkwe can host a simple apache2 server with php and phpmyadmin and mysql on the pi once its done - Havent pushed code yet
- major web addition
- added user name and password system
- Uses Personal MySQL-Server Can Be Installed On PI With
Sudo apt-get install mysql-server phpmyadmin - To Make A Account Goto Create Account/register And Enter Your Username And Password (Will Make Prettyer) and it will put your data into the table of users with a default rank of 0
- Rank 10 & Higher Can Use Sliders, Rank 50 & Higher May Use Admin Page ( Havent Done Yet )
- Once Youve made A A Account You Can you The
Login PageAnd Enter In Your user name And Password It Will Start A Session In php And create a cookie with your name and rank as a backup the cookie only lasts 5 minutes though - To Get Your Rank Assigned Ask Someone With MYSQL/PHPMYADMIN database accsess
- Added Scripts to compile and run the code.
- Attempted to get the high powered servos directly on the Raspberry Pi GPIO pins with no luck. I think there is not enough current available from the Pi to run them. Will try using the Hummingbird boards we have, failing that we can buy a board for the Pi that is specifically designed to run servos.
- Added A
Landing PageWhich Lets You Click Diffrent Buttons To Navigate to/controlor/web/webcontrol - The old
/webwas moved to/web/webcontrol - Added Background To .HTML Files
- Also For Some Reason In Github Desktop it Says I Added A + Tags To The Beginning Of Most Lines idk Why?
- Restlet Server now serves a web page that has simple slider controls for controlling a turret. Web page uses JavaScript and JQuery to create the sliders and collect input from them and send it to the control server.
- Added a
/controlresource to the server for getting the current turret position and setting it.
- Added a simple web server using Restlet to serve REST resources that can eventually be used to control the turret
remotely via the web. Added
restlet,gsonandjsonjars thelibdirectory. - We need a script to compile the java code on the Pi. Compiling Java is very cumbersome, if we had a full IDE on the Pi we could do it using that, but since we are coding on IntelliJ on Windows it needs to be recompiled on the Pi.
To compile, from the project root directory run:
javac -cp ./lib/*:./src/main/java/* src/main/java/com/nerf/turret/ControlResrouce.java src/main/java/com/nerf/turret/NerfTurretServer.java
And to run it, from the project root directory run:
sudo java -cp ./lib/*:./src/main/java/* com.nerf.turret.NerfTurretServer
Ideally we'll compile in to a target directory next to our src directory.
- Prototyped Servos and a simple turret that moves up, down, left and right.
- Servo object can be configured to have a GPIO pin and a position and has the functionality to move.
- Turret contains two servos and translates up, down, left, right commands in to movement values.
