Thread: The Mean Machine Revamp

  1. #1
    Following Robots Live Grantham 2019 I have decided that The Mean Machine needs a more effective
    weapon system.
    Originally The Mean Machine was built to take part in Robot Wars and hence the different weapon system was
    developed with the view that if there is 10 or 20 flippers or wedges applying and only one or two with clamping jaws we would have a good chance of getting on the show due to the policy on diverse Robots.

    We got the Robot ready for Robot Wars 11 which of course never happened so live circuit beckoned.

    Grantham- This was only the second outing for the Mean Machine and it was not a brilliant performance, I had
    bought a new speed controller to control the Jaws and this bit seemed to work very well although I felt having
    two fan cooled ESC waiting in the the arena draining the battery while the compare talked for 10 mins was irritating.
    I might look at the possibility of switching the fans off with the remote in case of long delay in the future.
    So Mean Machine seemed a bit sluggish compared to last year and suffered a broken chain in the first battle.
    We managed to repair the chain and went in again against Iron awe and Thor and two more flippers, Mean Machine seemed sluggish again and the compare had gabbled on again beforehand-we got flipped at least 3 times within seconds but managed to drive away,a couple more hard hits and we were dead.
    Upon reviewing the damage we found a motor had come loose leaving no drive at one side and the wheel protection flap at the other side was pushing against the wheel leaving effectively no drive.

    Conclusion-everything happens quickly, so a fast weapon is needed, the basic shape of the Robot will remain
    the same but we will fit either an side axe or concealed spinner in the jaws which will make it unique whichever
    way we go.

    Looking forwards to seeing/reading this one. Just bear in mind that a spinner wouldn't be permitted at Robots Live events so if you were looking to go to those events, I'd possibly advocate side axe/grabbing arms.

    tbh i feel it you made the drive chain wider which would help with control and maybe look into a dust pan with a clampy claw/jaw thing ?

    Thank's Mark and Lucy-I feel if I added a dust pan it would only help with sweeping up my own Robot bits as they were broken off
    -those flippers are so powerful that the 3 mm steel teeth were bent like Plasticine but any ideas are always welcome.
    The wheels on Mean Machine are a little too close together and too far back and I think that's the main problem with control.

    I had another chance to look at the Mean Machine today as two of my feathers are ready to go

    for Robodojo next week.

    I was not happy with Mean Machines performance at Robots live Grantham 2019 as previously stated

    and have decided to do a real cut and shut job to rectify poor drive issues.

    For reference see Team Death New Heavyweight-Basically the Robot is front heavy so this gives the effect

    on the rear wheels of tickling the arena floor instead of putting down good traction.

    So my plan is to put the wheels just behind the jaws which will shorten the body of the Robot by about 1/3 rd

    but make it wider by the same and it should be much more manoeuvrable .

    This is a major task but I think the final results might make Mean Machine much more competitive .

    I will post some pictures as I progress.
