Hi,

Is there any way to measure the Battery level (the NiMH battery that comes with the kit) using roboBASIC language ?

If you look at the last page of the Robonova manual it describes the low voltage warning setup. This measures the battery voltage, which is about all you can do easily. Battery voltage is some indication, but not very reliable indication on NiMh batteries.

Note the voltage Vcc must come from the centre pin of one of the servo connectors which have battery voltage on them, The centre pin of the AD6 has a regulated 5V which is no good. Any two equal resistor values around 50K will do.
