Note: don't worry about USB Debugging.
That's only used to get the screenshot.

4. Run app

You can click Open after the installation screen or you'll find the app under LCMDroid in All Applications.

Shallow prototype

This is not a ready-to-ship prototype, so some portions are deliberately shallow:

Data plotting should be parallel for all channels in real time. In our prototype, we show each channel drawing the data each time it is selected.
All data is canned. Once the canned data runs out, it is pseudo random.
Double-tap on the graph screen is unimplemented.
No artwork (such as the application icon) is completed.

Scenario Instructions

When testing our application try to imagine yourself in the following situation:

You are programming a small flying quadrocopter to follow navigation commands. It is presented at the figure below as the black bended clipper.

It needs to go for few meters in the X direction and then int needs to turn left.

The quadrocopter carries a laser scanner which measures the distance between the quadcopter and the ground and the wall.

The quad applies controlls to its motors which make it go or turn.

Other notes

This application uses a number of different libraries, including plotting from arity-calculator, which is licensed under the Apache License, Version 2.0. We have made several improvements to their code and intend to submit our patches upstream.

Patches include:

Point-based multitouch zoom (instead of zooming to the center in all cases)
Multitouch drag support
Infinite-horizon scrolling
Small bugfixes
