I am new to LMR and new to robotics, so i am slowly learning.
I have created an Autonomous Robot using the motor driver L293D, arduino duemilanove & Sharp IR Sensor.
Everything seems to be working fine when hooked up to the usb cable, does exactly what it should do.
When i try to run everything off batteries it does not work. I made the first mistake in trying to run 2 motors using a 9v battery, and after reading the post on here about which battery to use, i went and purchased some NiMH rechargeable batteries.
