Due to being a hobby robot platform, there is the very small chance that the power is not connected inside the robot.

1. Consult this tutorial: https://synthiam.com/Tutorials/Lesson/69?courseId=3

2. Let us know if you see any plugs or wires disconnected from inside the robot

And welcome to the forum!

Welcome @Lind12950.

Further to what DJ has mentioned above, one possible cause for now power could be that the fuse needs replacing. The tutorial for fuse reacement in below...

Roli Fuse Replacement

Cool will check it out tonight, thanks for the info

No problem. If you still have problems, post back here with what you tried and we'll try to help you further.

Unfortunately neither fix worked...I checked connection with my multimeter and it appears the switch is bad. It appears to be crimped or soldered very well and is difficult to remove. I connected the two wires to bypass the bad switch and the robot quickly turned on, but then immediately stopped because the fuse blew! So I may have 2 issues a bad switch and then something else that blew the fuse. Also will somebody send me a switch and fuse since it is still under warranty? Is there something else going on with the robot? My kids are getting impatient and so am I, ready to start programming and seeing robot move.

There is obviously something else going on. The fuse is a simple standard automotive fuse so that would be easy and cheap to replace from any automotive supply place or most stores like Walmart. Of course it would likely just blow again. It takes a good bit of current to blow that fuse so it looks like there may be a short someplace. Anyway, that's what I would look for first in the wiring. See if there is any obvious place where the wires are touching and causing a short circuit. This, as opposed to the open circuit you have been looking for.

Maybe you could take a few pictures of it so we could see the wiring for ourselves. Often experienced eyes can catch details the new user can miss. A good shot of the EZB4 (brain) where all the wires plug in would be very helpful. If you already have the body open, some shots inside of it would be good as well. That's what's great about the internet, instant visual communications.

EDIT I just recalled that the Roli also contains an HBridge device. This is a higher current device for driving the tread wheel motors. A good, close up shot of it would also be helpful.

Also, is it possible that, when you placed a jumper across the switch you may have touched something else as well? I don't have a Roli so I don't know how likely that would be, but I thought I would ask.

I agree with WBS. Some close up pics of the H-Bridge would be useful. Several came mis-wired from the factory, and that could potentially cause the fuse to blow.

Where are you located? If you are in the DC/Baltimore megalopolis, I could arrange to meet you Sunday and help troubleshoot in person (I really wish the forum displayed more than just country for location).

Here are the pics...if it keeps blowing fuses will ez robot warranty the fixes? it has never worked since I got out of box and would like to start using it soon
