Did the treads or arms ever move? If so maybe the H-bridge just died and not roli... If he never moved at all see here Roli won't move

If everything is dead, no lights no sound then check the wire connections, battery and main fuse...

Thanks Richard - it is probably the fuse as nothing lights up - presumably I have to take the lid of the beast to find it - is this right?

Could be a wire connection too... Remove the ezb then re-seat it... check the battery wiring too... The fuse is probably underneath where the ezb sits...

I know the ezb works as I can plug it into the developer kit (which I also have) so the problem is between the battery and the ezb .... thus I think it is a fuse issue ... but I am not sure where the fuse is!

Cheers

Sounds like it's the fuse... Check the battery and battery wiring too.... However it is more likely the fuse or wiring if everything is completely dead....

Thanks Richard - do you know where the fuse is?

It should be underneath where the ezb sits in Roli near where the battery is.... You will probably have to crack him open so to speak.... I can't imagine it being too difficult to get to...
