BT Bot Control

Robot remote control & IP Cam viewer via WiFi and Bluetooth. BT Bot Control allows you to control your robot over Bluetooth via joystick or orientation sensor, and optionally seeing what it sees via an IP camera. You can also use an app (i.e. IP Webcam) to convert a spare Android phone to an IPCam.

:: Configurable camera URLs

:: Joystick Modes: Default & Simple Modes or use your orientation sensor.
:: Provides both direction and acceleration to give you complete control (default joystick).
:: Display sensor and other data from robot / microcontroller.
:: Up to 8 additional commands.
:: Configurable Bluetooth connections & packet interval.
:: Supports most microcontrollers.
:: Sample Arduino Sketches provided (below link).
:: Small device screen size friendly (optimal on tablets or large phones).


Technical Stuff - There are two joystick modes:

:: Default Joystick Mode:
Moving the ball around generates X+/- and Y +/- which can be used to interpret both velocity and direction. These are packaged and sent in the following format: sX=val,Y=vale i.e. sX=75,Y=55e where 's' indicates the start and 'e' indicates the end. In this mode, when you press a Command Button, values are sent in the following format: sC=[val]e (i.e. For Command #2 sC=2e is sent) where 's' indicates the start, 'C' indicates it is a command button, '2' is the value that you want to parse and 'e' indicates the end. These values can be parsed to have your robot move and perform additional tasks. (sample Arduino code provided at link below)

:: Simple Joystick Mode:
Tap arrows to generate single character values depending on the arrow you tapped (i.e. the top arrow sends U). Values generated are: U (up), D (down), L (left), R (right). Tapping the center of the joystick sends an S value (stop). Tapping any of the command value sends the respective command number. i.e. tapping Command Button 3, sends 3. In this mode, your micro-controller code can be simplified as need only parse single character values.In this mode, when you press a Command Button, values are sent as single characters in the value of the Command Button. i.e. If you press Command Button 3, the value 3 is sent. (sample Arduino code provided at link below)

:: Other Stuff:
Lite Version: This version has all the features of the Pro version. However, Bluetooth data will be sent as '9's. i.e. 'sX=9,Y=9e' and 'sC=9e' (or 9's in Simple Joystick mode) which will provide you with enough to determine if this app is right for you. The Pro version has full functionality enabled, and can be yours for less than the cost of a coffee.

Note: Orientation sensor joystick mode may not work on all devices. Screen re-sizing may have issues on very small phones.

There are many affordable Bluetooth modules available on various auction and overseas sites. Details can be found at the below URL. If you have any suggestions or feature requests, I would like to hear them. If you like BT Bot Control, please rate it.

Update: WiFI Bot Control is now available. Control your robots like you do in BT Bot Control, but over WiFi!
