Once the opponent is in place, the spear will jab diagonally straight into the underside of the robot.
    i was thinking a more central spike might help

    It would in terms of aim but placing the spear in the middle means the weight is off balance so could affect handling. If I lay my hands on a suitable replacement, I'll swap the motor over.

    Did a rough weigh in and it comes to about 11kg on the Bathroom scales. I assume there is a better way to weigh it?

    Short of taking your robot to the post office or local supermarket and asking them nicely, get a set of these if you can afford it: http://m.ebay.co.uk/itm/LARGE-Digita...%257Ciid%253A9

    Thanks, I'll see about ordering one fairly quickly.

    For the metal front, I think a door "finger plate" will be suitable for this application. Once acquired along with some right angled strips to cover up the joins in certain places, I'll get some brackets shaped into ramming spikes and non return ridges.

    Whilst that is going on, I'll gut the Badger, drill out the spear and removable link holes (using some XT60 connectors here), rewire it with the links in and mount the weapon motor properly, which would leave just the weapon itself to shorten and then done sans any cosmetic work, hopefully by next Monday.

    Well the last couple of days have been eventful.

    First, The Honey Badger is not going to Insomnia. I got told just before I found out that the Badger was accepted that I was meant to be in Oxfordshire for a wedding on the Sunday. I pinged Robo Challenge to see if we could still compete in the side events but they are reserved only for folks who have competed in (and have been knocked out of) the main competition, which is fair enough. However, since I can't compete fully over the weekend, I've had to withdraw, which has really, really annoyed me as I wasn't aware that we were meant to be going.

    Second, the weapon motor has decided to break on me. It had been running OK on and off for the last few days but there seems to be an issue in the gearbox, which is riveted shut and I can't undo. I've dismantled the motor, clean up what I can see and it still doesn't want to play ball so with the withdrawal from Insomnia, I am going to put the spear on hold and just sort out the running gear first.

    Apart from this, The Honey Badger is pretty much complete, bar the removable links. The last of the XT60 connectors arrived this morning so I'll be soldering all that together tonight. Power light is in and adjustments to that back panel are done so it shouldn't ground out any more.

    Make a effort to tidy up the wiring in The Honey Badger yesterday. I had originally planned to drive both drive motors off of a single battery set but it wasn't having it (one side was OK, the other wasn't) so I changed back to similar wiring used on the original Badger, 1.2ah battery per side. Made some minor adjustments to one of the side panels and it seems to run cleanly in my uneven garden so that is a plus.

    I'll be making a effort to get the removable links sorted out this week however, whilst one motor spins correctly in forwards and reverse, the other side works fine going forwards but at 100% reverse, it suddenly stops. I suspect a fault in the wiring loom somewhere but I can't think where it might be.

    For the moment, I've removed the weapon motor, battery and wiring. Though it is all intact, the wiper motor is completely stuffed. I'll take a bit of time reconsidering the weapon on The Honey Badger but I expect I'll stick with my decision, albeit with a different motor and a custom built cam mechanism to drive the spear.

    Photos of before the tidy up, after the tidy up and a example of just how wonky my first go with a jigsaw went. :S

    looking sweet! Cutting isnt too bad, just needs a bit of sand paper or such!

    Thanks! Been touching up where it needs it with a Dremel to make sure it clears the floor. Once happy, I'll get some edging metal, such as carpet threshold or similar and cover the unsightly bits up.

    Removable links and LED power light installed now. Batteries need securing down with a metal brace (sitting on Velcro tape at the moment) to be compliant with the rules but really, the robot is now together and would probably survive a fight or two, unlike it's predecessor.

    Speaking of the predecessor, I've put the drive motors into the test frame I had laying around, remade the wiring from one of the speed controllers that failed and put in the weapon speed controller for the other wheel and now they are running. Unsurprisingly, one of the motors is rather gravelly (where the hammer hit it has probably bent the shaft a little) but slackening off the screws between the gearbox and the motor appears to have helped. The original shell does fit over the test frame as well.

    So with the original now running and the successor running as well, I am seeing a old vs new fight between the two now (although still open for any car park matches).
