I am trying to use the ez-B v4 to make a wall-E robot. I am confused where the power goes. Does the Li-po power the servos or the Controller. If it powers the controller then how exactly to use it because when I tried cutting the two big red n black wires on the li-po there was a spark and the battery puffed up which is why I had to throw away the battery.
Upgrade to ARC Pro
Synthiam ARC Pro is a cool new tool that will help unleash your creativity with programming robots in just seconds!
If you bought the dev kit, there is a barrel adapter that can be connected to the battery. The + side of the adapter connects to the red wire and the - side to the black wire on the battery.
From there you can power the ez-b. The power for the servos will come from the ez-b which will then be connected to the battery.
We are all excited when we get something as cool as a robot platform. That is why we do what we do. Everything that you do, pause and think about it before you do it. Always take the long road when working with robotics. It takes longer but always produces better results. It is like programming in that the eloquent solution always produces better results than the expedient one.
Nobody here meant to make you feel stupid. We all started somewhere with this passion. We all have made mistakes. We all still make mistakes. Hopefully the ones we make are not too costly.
Let us know if there is anything you need help with. It is best to ask first to verify than to have a costly mistake.
