HIRO-group/TactileContactLocalization

Repository files navigation

To use and edit the app, make sure you have Matlab App Designer installed. After cloning the repository 
with "git clone https://github.com/HIRO-group/TactileContactLocalization.git", run the main app window named
"ContactLocalizationApp.mlapp". 

The window will automatically search for a serial input connected to the host 
device streaming sensor values with a comma delimeter. This has only been tested with Arduino microcontrollers
but should still work as long as the serial input is what it is expecting.

######## Arduino Connection #########
skinObj -> Serial connection to the arduino. Use this when calling readSkin

% Object model data for the object used in data collection
>> touchData.obj  -> 		     Struct for object data
>>>> touchData.obj.v ->		     [nx3] matrix of vertices that form each face verts  
>>>> touchData.obj.f ->		     [mx3] matrix of vertex locations in implied body frame
>>>> touchData.obj.fileLoc ->	     string of object file location from main directory
>>>> touchData.obj.Points ->      [nx3] matrix of discrete points along the surface

>> touchData.stl  ->             Struct for stl data
>>>> touchData.stl.fe ->         Struct containing all information of an fegeometry
