Following on from Colins post about the car boot, I'll post about how some of it came in to use in todays building session!


Today was mostly spent getting the double sprocket ready - this will take the motor chain over the sprocket, and in turn pull on the jaw chain. This was deemed a better solution instead of having one rather long chain running most of the length of the insides, splitting it into two seperate ones.
The first thing we did was to prepare a little mount for the sprocket, so it could turn independently of everything else using the bearings I had acquired over the week (see image 1). This was a fairly simple task, once we had decided on the suitable metal thickness and such to ensure strength over load and no bending possibilities.
After we'd done, we needed to find a place to mount it to. It became clear last week that we'd need to make a mount ourselves, as the ideal place was floating above everything, and we're not wizards nor above the laws of physics just yet.
Enter the stabilising towing bar Colin mention on the previous post!
After sending it on a crash diet course, courtesy of an angle grinder, it was cut down in length to fit neatly on the bottom of the robot. After being bolted in place (see image 2), so it could be rapidly removed so we can get to the internals and replace wheels. We lined up the previously put together sprocket and mount and it all lined up neatly (see image 3)
Unfortunately, the time ran out before this was put together, Colin may find the time to do it during the week, if not, that'll be the first thing for next sunday!
