"Thanks, but I am now wondering if mission planner can natively take in keyboard inputs for controlling the UAV without external software, and if so/or not, how do I modify it such that it can natively take in keyboard inputs as controls?"
I understand that we can use a PC gamepad/joystick on the mission planner to operate an arducopter. Since that is the case, is there any way to modify mission planner such that we can operate the UAV via a PC keyboard.
