Class VirtualJoystickView

java.lang.Object
  RelativeLayout
      org.ros.android.view.VirtualJoystickView

All Implemented Interfaces:

org.ros.message.MessageListener<nav_msgs.Odometry>, org.ros.node.NodeListener, org.ros.node.NodeMain

public class VirtualJoystickView
extends RelativeLayout
implements org.ros.message.MessageListener<nav_msgs.Odometry>, org.ros.node.NodeMain

VirtualJoystickView creates a virtual joystick view that publishes velocity as (geometry_msgs.Twist) messages. The current version contains the following features: snap to axes, turn in place, and resume previous velocity.
