    Thx. Yeah, it was. It was a pain to keep running at all and as much as I like the machine, it really does need a redesign to address a lot of the problems with it. I'll keep this version around for now but I am hoping to have a new shell and some various upgrades to what is there for EXR Cheltenham.

    Antweights
    With BotFest 3 in September, I've got a bit of work to do in getting the Ants I have ready to go. Typically, with the Ants I have for BotFest, I loan these out to a different driver because I feel that me competing in my own event is a bit contentious plus, I am normally running the main bulk of the show on my own so I need to run the administrative stuff as well. However, since BotFest 2, my Ants haven't seen any action in an arena.

    Amai is running fine. It needs the shell welding/gluing back together in places but otherwise is pretty much ready to do. I did have to swap the battery out with a different one as I'll explain later. I finally picked up a DSM2 controller so Ramu will finally see some action in an arena now! I'll need to order a new LiPo for it as well but it will run again. The famous Skittles robot Osu has been retired from combat but I'll still use it in games and such. I need to check the LiFe battery in it but I suspect it is fine.

    Ikari, on the other hand, was dead by the end of BotFest 2 and it went into that event very ill with a faulty motor and/or speed controller so it needed rebuilding. After salvaging some wood for a frame from the BotFest arena, picking up a NanoTwo LT and some new motors, Ikari 3.0 is born. It still needs painting and a bit more reinforcement but it is all there, ready to go. Because of the space conditions, I had to use the battery from Amai but in reality, this is not a big deal. It is quite quick and features a lifting arm mounted to the bottom of the robot to jack it up to act as a lifter (kind of like how Shu! worked).

    Apologies for the rubbish photo, the lighting in my office is not great at night.

    Next thing to do is get a new arena floor cut, painted and effects added.

    Azriel
    I've decided to take the plunge to refit Azriel with brushless drive following a successful conversion I did a few months back. I was planning to refit the axe motor with a brushless motor as well but I think that would require a bit more work to make it work correctly so for the moment, drive only. I'll be using XK-3674 1650kV inrunner motors in this one, which is a little narrower and longer than I would like but that is what I have so it'll do. I've also picked up another 3S LiFe battery so it'll be running at 6S LiFe.

    If it turns out to be too fast on the 100mm wheels, I'll put this one on 75mm wheels because one of the things I liked about Azriel at EXR Bolton was the controllability of the machine. It'll always be a case of finding a balance I guess. By my calculation, the new motor/gearbox setup should be spitting out ~2300RPM on the output shaft ((19.8v * 1650) / 13.7) at full power which I think is ~27mph on the 100mm wheels and ~20 on the 75mm wheels. Might need to configure some limiting as well :P

    Ramu
    This is the Shakey robot I bought last year from Greg which until recently, I've not been able to run because I didn't have a DSM2 controller (thanks Euan!). It is a simple rambot and it does need a little bit of attention but it should still functionally work. There are little things I want to do to it, like paint the thing and perhaps remake the front wedge on it but otherwise, it'll go again. A new battery has been ordered for it.

    Jibril
    The designs for Jibril 2.0 are nearly done, down to picking the materials now and will be ordering the materials in one go at the end of the month. I'll be reusing most of the internal components out of Jibril 1.0x but replacing things like the silver steel shafts with hardened ones in places and locking down the gears on the axe gearbox properly this time because the Scythe has fired, in the 15.75:1 gearbox configuration, a magnificent total of one time during the entire weekend. I may also end up rewiring the thing because right now, the wiring loom in there is a bit pick'n'mix and as EXR Bolton proved, the soldering is a bit rubbish in places.
