Driving "Roberto the Robot" on low and or almost dead batteries does not make for a very fun experience. In order to correct this problem, I decided to install an alternator on the top deck plate. Therefore, when the 6.5hp engine was running the batteries would charge and the robot would operate as usual. The alternator I used is a 120 amp Deutz Letrika alternator from Surplus Center.
Want a cool project to build during the fall? Hate sweeping leaves and or scrubbing concrete?
Here is Roberto's lift kit that is its actually the weed remover.
