Adding joy package for joystick control. Takes a joystick working with linux and ports it into ROS.
Tested velocity control and added yaw and throttle control to joystick.
Added joystick_control node, with a skeleton of a JoystickControl class,modeled after the keyboard_control node. Eventually it will takemessages from joy_node and call velocity_control in MikrokopterControl.At the moment, it compiles but does nothing.
Added velocity_control to MikrocopterControl class, which was added towork with joystick control. Takes forward and lateral speeds andcombines them to set pitch and roll.
auto-level in mikrokopter keyboard control
fixing forwards/backwards, adding level function
Added ncurses for key input. It can now publish at a rapid rate becausethe key input is non-blocking, and after it exits the terminal is notscrewy, but it's not an ideal solution because ROS_INFO no longer works.
Encapsulated the stuff in nav_lib into a class, MikrokopterControl.
basic (not-yet-working) flight control via keyboard
Added a keyboard control node.
The new file, keyboard_control.cpp, mimics the turtlesim keyboard reading. It responds to wasd, arrow keys, and "rf" (for up/down), and right now simply outputs ROS_INFO to show what was pressed.
Created nav_lib.cpp/h, with functions forward, backward, left, right,and stop to set the mikrokopter's movement direction.Replaced code in wasd_nav.cpp's main with forward(pub) and stop(pub)from nav_lib.cpp.Added nav_lib.cpp to CMakeLists.txt
