As is customary for this thread, here is the review of Team Kaizen's performance in 2021.

Ramu/Osu/Ikari/Amai
The ants, accompanied by a new robot from a first time roboteer called Ghosty, did reasonably well considering the competition at BotFest 4. For 2022, I'll be retiring Amai 1.1 and building a replacement robot which interestingly enough my Dad suggested the design for when he came to BotFest 3. Ikari will also be rebuilt to version 3.1 to address some of the issues in the 3.0 version.

The Honey Badger
The experience at Rampage in Chatham was a brusing encounter but fun nonetheless. The drive motors in particular are completely knackered and need replacing along with the body which I am not happy with overall. I'll be looking to make the 4.2 version more compact and with stronger/faster motors and better protection around the wheels as a whole. The flipping arm mechanism though I am really pleased with and may carry that forwards to other robots.

Azriel
I must confess I wasn't happy with Azriel's performance at Robots Live! in Crawley. The axe worked well enough sure but there were/are a lot of build issues that often meant an early retirement from the melee matches and wouldn't stand up in a competition match. I had originally been planning to completely rebuild Azriel into a 2.0 version but I am instead going to concentrate on the electrics for a 1.1 version (which is where the majority of the problems are) and tidy the whole wiring loom up so that it'll be less likely to shutdown during a fight.

Jibril
Like Azriel, Jibril didn't perform as well as I would have hoped in Crawley. It moved OK but the gears in the drive need replacing and the axe needs retiming to ~25:1 with proper independent mounts. The armour held up fine but one of the side arms became bent from being flipped and landing awkwardly. If being totally honest, I think the main issue with Jibril is the baseplate where it isn't stiff enough. I will see if I can add in a brace for the 2.1 version.

So with that all out of the way, I won't be able to work on the robots until I've moved house as practically all my machining gear and robots themselves are in storage at the moment. This also means that I can't work on the BotFest arena until the whole process is done and that could be a long, long while (as in late spring time) but the process will be worth it as we are looking to move to somewhere with a garage and a extra special something. I am hoping to find the time to edit the BotFest 4 video this week to finally have that released.
