Hey Gav,
Doesn't look like I got those connectors in the basic Kobuki kit, must only come with the Turtlebot kit. Will have to see if Jaycar or somewhere has the connectors then. Is there a specific name for these sort of connectors other than a "6 pin connector"?
Yeah I realise that it only charges the notebook while docked, hoping my notebook last as long as the Kobuki does! Otherwise I might look at installing an external notebook battery for it.
