This week we again tried to connect the port expander, but it didn’t work as expected. We’ll try solving this problem next week.
But we successfully connected our 9V battery to the DC-DC, so we can now use one battery instead of two. This also allows us to easily connect an emergency stop button, which is required. On top of that, we began creating our 3d-model for our new case, which looks quite good yet. Last but not least we measured the power of all content of the bot, so we can now choose the right fuse we have to use.
