  1. Team Darklight - Something Completely Different (Beetleweight Meltybrain); Retro

    Despite having run Something Completely Different (SCD) at four Beetleweight events in 2018, I never did write up a build diary for it. Given it's 'retired', it makes sense to do a bit of a write up...
  2. Team Darklight - Sawcerer (Featherweight overhead saw)

    It seems that I've built one too many Featherweights over the last two years I've been building; now in to build number four, and this time, something that's not an axe, but something that's going to...

    Post Extreme Robots Cheltenham

    The Cheltenham event was really good fun, and was a high for Broadax 2, followed by a low.

    So in melee 1 of the Saturday session, Broadax 2 was declared the...

    Preparing for Extreme Robots Cheltenham

    8529

    Many, many tweaks, changes and updates have been made to make it (hopefully) perform better than it did at KOB UK.

    The lids would hit the front...

    I echo what others have said - if you get the remaining minor issues ironed out, Strix will be a fine machine! I don't think it will take much work either.

    I never got to fight it so you have to...

    I have made two axes bots with chains and one with spurs, and I'll say that there's no right or wrong solution - each has advantages and drawbacks. You do have to be more precise with spur gearing...

    If it were me I would keep it as simple as you can.

    With most transmitters you can set an exponential curve that means the slightest twitch on the channel puts it at 100% throttle / throw. You...

    These were CAD designed by me but I didn't print or make them myself, I got them water jet cut as part of a larger parts order.

    I will be making a V2 hub for these that will be 3d printed, that...

    I use an older revision of that one in Broadax 2 (same thing just with longer aerials). It does failsafe all channels if the failsafe process is followed correctly.

    I would grab a LemonRX receiver for DSMX use with the DX6i transmitter. Many roboteers use these and they have a very simple setup for failsafe

    I thought about this when I built previous robots. I think simplicity is the key, the less there is to go wrong the better generally!

    There's a few ways to do this, for me, the clutch is literally on the transmitter control in that I pull it to stall either direction, and it has rubber stops either end of the travel. If I were to...

    So now back from KOB UK, here's a writeup on the event from us!

    The good
    - The drive
    - The polyurethane cast wheels
    - The axe mechanism itself

    The bad
    - The drive
    - Hobbyking VESCs

    With KOB at Insomnia 63 fast approaching, I've been concentrating more on the actual build than keeping progress here. I have taken a lot of build photos which I'll upload here at some point, but in...

    Purely by coincidence! There are a number of 'inspired by' design elements of a number of different Axe bots

    More progress made today, finished the armour mounting brackets and the drive plate attachments.

    Did a quick second drive test:

    Yes, I used KCut for this. There was a bit of a delay on the bending but the result is pretty good

    Here's the first axe test on a VESC. Still more tweaking to do, the robot wasn't fully charged here yet it still bounces.

    Thanks, that's very complimentary! Will have to actually finish it first!

    To that end, got the VESCs configured and the drive propped up for a little test. After trying VESCs I don't want to go...
  21. Team Darklight - Broadax 2 (Featherweight Axe/Hammer)

    Here we go again!

    As a lot of you that attended Extreme Robots Manchester in 2018 will know, that whilst the previous iteration of Broadax potentially could have made a great brushless axe, it...

    Ah, OK. Do you get the three audible beeps at different frequencies on powering up the ESC? I couldn't really hear in the video. If you only get two, the one phase is missing and that's the...

    These look like the RedBrick 125A ESCs. You mention using a different hex file, is this labelled rb70a3?
