Another Sunday passed!
For the first time in a while, I'll be delivering the blog update this time around! We were down a man again, as though I recovered from my illness, Niall was up in Scotland, but should be back for next week!
Today was another day of misses, with a recovery towards the end.
As soon as I met up with Colin, we took a trip to Maplin, and got some ceramic 1 ohm resistors of varying wattages. These were to be used to try nulling an issue with getting things up and running, when the battery was connected there was a huge spark. The plan is to have a resistor make the first connection, and ease the flow of energy in before the main connection is made, similar to how a British style plug works, the earth pin is slightly longer so it always makes contact first, where the longer pin would be the resistor pin here.
After getting back to the workshop, we had a go at getting this going, however instantly ran into issues. Unfortunately try as we might, our new Ragebridge ESC wasn't powering up, and after slowly removing stuff from the circuit trying to problem solve the faulty component, we came to the conclusion the actual ESC seems to be not enjoying the situation. We will hopefully have an update on this situation and a way to resolve it by next Sunday.
Unfortunately, all this took around 2 hours, but after realising we were not going to make progress there, we moved onto some more fabrication. First on this order was to make a set of battery holders on each side of the bot, they'll conveniently hold the batteries in place, but also add additional protection, as LiPos are not too fond of being pierced with hammers and axes, and competitors have lots of those! They've been put on hinges welded to the main body, so they can be quickly moved up and down in and out of place.
This didn't take too long, so we had time to do some work on the castors for extra handling, we cut a few pieces which will soon hold the castors in place. They'll be back with some springs, so they're always on the floor. Final order of the day was to drill a hole, for the castor to fit through. This last part will be repeated later on for other castors.
We currently think all major fabrication should be done within the next 2 or 3 weekends.
A few images for today;
The three ceramic resistors, all slightly different so we can play with what works better for what we need.
The rather large mess of electrics whilst we were trying to get the ESC to power up.

Locked and loaded, batteries in place!
Some previous fabrication work done by Colin, and a little of what was done today, and will be continued on soon, for the castors.
