User guide
Manual drive mode using the Wii remote controller
- Press one or more of the four emergency stops on the mud guards. This is to ensure that Armadillo is safe while it is powered on.
- Connect the main battery connector to batterypack (four lead connector block)
- The FroboBox on board computer should power on automatically (Press the powernbutton inside the box in the Atom version)
- When there is light in the BlueTooth dongle, release all emergency stops and press the blue button. There sould be a audible 'clonk' sound from the grey box, and lights on the two blue RoboteQ controllers should come on.
- Press button 1 and 2 simultaniously on the Wii remote to enable its BT discovery mode. There sould be rapidly blinking lights in one or more of the blue LED's on the Wii remote (the number of blinking lights indicate the wiimote's battery level). The connection is successfull when LED 4 (marked with four dots '....') is blinking slowly.
- The Armadillo can now be operated by holding down button 'B' while gently tilting the wiimote.
- Be careful! its a powerful vehicle!
