I was trying to reset the Wi-Fi settings on my Roli Rover EZ-Bv4 by using a paperclip. My hand slipped and hit the ground prong on the EZ-B. I ran into issues like this before on my IO-Tiny. With the IO-Tiny, it was fine, the alternative power harness broke. Maybe what happened was I contacted both the power and ground rails and shorted the EZ-B. I can't afford another EZ-B. Could someone please help me? I'm sorry if I'm breaking a rule by posting this, but I don't know what to do.
There were no pens that fit in the hole to reset the Wi-Fi connection.
I'm also not home so I can't check the EZ-B with a different battery or check with a different battery.
First thing I would check is the fuse then look at the board see if anything looks burnt.

I do have good news, I did buy an EZ-B that did come with a base. So I can use that ones fuse for this. I also ordered a humanoid base so I don't need the base anyway.
I'm hoping, like Herr Ball mentioned, that your fuse is blown. I really know that feeling in the pit of the stomach when stuff like this happens to me. Good luck!
if you need a new fuse then it's simply a 20 amp automotive mini blade fuse. Here's the link on EZ Robot's age on how to replace it: https://www.ez-robot.com/learning-robotics-fuse-replacement-humanoid-robot-kit.html
Honestly, this will happen at least once to anyone using an EZ-B. This isn't the fault of EZ-Robot or any of the original designers. The fuse is designed to be used at least once. It's like a case on a phone, you will drop your phone at least once and the case can prevent damage to your phone. There's a reason why the fuse is needed, for reasons like this. I still have other batteries that I can test the EZ-B with, and I have to wait until the parts ship. If the EZ-B is broken, I won't be happy. I bet it's the fuse.
The bad news is that shipping takes three weeks.
Open up the base and you'll see the fuse. Look closely at the center. You should be able to visually see if the filament is open or not . If you have a multimeter tester you can do a continuity test across the fuse to confirm if it's blown or not. Do a google search for lots of help on how to check a fuse or anything else for a continuous unopened path (continuity). It's a simple thing to do and a basic skill to have, especially when you're building robotics.
If it's blown just go down to a auto supply store and get a new one for a couple dollars. No need to wait 3 weeks to see if you have a bad fuse or not.
