2016-12-08 00:45:55 -0500 asked a question porting navigation package to android

I want to setup a master using a Thinkpad Notebook, and driving a robot base(such as turtlebot) using a android device. I have tested the demo application, http://wiki.ros.org/android_ndk/Tutor... , it works well. So I guess that it would be possible to porting the navigation stack on the android.

On android device, it will control the robot base, so I will write code to control the base and publish base status, robot pose, etc.

Besides the robot base control, My question is how to implement the navigation on the android device? My goal is: user touch a point on the android device screen(map on the screen), then the android device will drive the robot base to the touch point.

I guess I should do the following works: 1. I will need to write node on android to get map from the master. 2. write node on android to read the kinect data and publish as the laser data or point cloud for navigation.

what else should I do?
