Exposure 2.0 completed!

 All metal has arrived and parts printed, and we just about got in weight (more on that later)!

The first important parts to do were: printing the chassis, weapon uprights and front armour. Then, after quite a steep learning curve, we assembled our 1806 conversion drive without much difficulty. We had our first go at casting polyurethane wheels, and they came out really well and feel really grippy.

We then had to wait a little for our new metal parts to arrive, and I decided to re-print the wedge with more walls. However, we finally ran out of green TPU! This meant we had to use the black TPU that we had difficulty printing, but after a few setting changes it went perfectly. Once the metal had arrived, it was time for a test weigh in. This unfortunately weighed in as 1.595kg with the heaviest setup (4 forks). Even with just two forks, it was around 55g overweight. This led to us completely redoing the wiring, trying to cut out as much unnecessary wire as possible. I reprinted the weapon bulkheads with large cutouts and less walls, which saved around 20g per piece! When we went to weigh the fully assembled robot, it was still 2g over, but swapping out the fork bolts for some much shorter ones did the trick and we are now 6g under the weight limit! 

I think this version of Exposure is such a large increase in technology and design from the old one, and I love how it looks! The new drive make it so much more enjoyable to drive,  and I am actually quite confident for RoboDojo this weekend. Im looking forward to testing these upgrades at Dojo before Battle in The Burgh, which we managed to get a place in!

We took a trip to York at the weekend to compete in our first official event as a full competitor. Upon arriving at the venue, we realised we would have had no chance of finding it if we didn't have Thomas Yau there to point us into the right building! We were among the first to arrive, so we had time to set up and grab some space before the rest of the competitors, and spectators, arrived. With a total of 31 antweights and 12 beetleweights, there was barely enough space for everyone to work on their robots. The competition format was a sort of group stage format so everyone got 4 guaranteed fights but could have more in the form of playoffs. Fight 1: vs Baby Dead Bod This was an absolutely terrifying first fight to have, Baby Dead Bod is an immensely powerful horizontal spinner so I was not happy to face it this early on. That was quick! A single hit on the weapon was all it took to flex the weapon into the pulley, sending it flying and completely shearing the motor shaft. This wa...

 Here is the full event video, I will write the timestamps for each fight. BBB x LHG Summer Showdown 2024- All Fights - Bristol Bot Builders Beetleweight Combat Robots The venue for this event was lovely, however the constant rain was a bit annoying, especially when it dripped off the marquees down the back of my neck! We arrived at the venue and went into the tech check with the heaviest setup we could run, and passed safety with no issues.  Fight 1: (06:46) My first fight was against Om Nom and Carbon Copy. I was happy with this match up as I would be the only spinner against a grabber (?) and a cluster bot. The fight began and I quickly engaged with one of the halves of Carbon Copy, using my full weight to push it into the wall and slice some material off the front wedge. I then reversed to give myself a bit of a run up and hit the cluster again, this time ripping the wedge off and slamming it into the ceiling. Whilst this was happening, Om Nom had somehow gotten stuck with...
