Step 13 Mounting the Batteries

If you haven't done so already , mount the batteries. Use L brackets to hold the batteries in place. L brackets are 90 degree brackets of metal that can be found in all hardware stores ( like Home Depot, Lowes, etc.) Just use the L brackets like I used it below to fasten the batteries to the chassis. Make sure the batteries are fastened tightly and don't move, because while the robot is moving you don't want heavy objects like batteries falling out. Also, notice that I put duct tape to cover the battery's terminals. You should do the same because you want to have the battery's terminal covered at all times to prevent short circuits.
