scruffy

Re: scruffy

Putting sacrificial lumps of HDPE on the corners sounds like a good idea. Anything to prevent them from cutting a gouge out of the steel, which an outer chunk of HDPE will do, as long as it's mounted firmly enough to not just get ripped off, is good.

Really looking forward to how this turns out. Naturally it will have a similar personality to Tormenta 2, it's going to be great seeing it work!

ok scruffy and night fury took a good bit of punishment at the 2013 champs, main faults with scruffy were a naff fuse connector and the deans used for the link also the main issue with night fury was the link which will be replace for something better

scruffy battering by TS3 was a great laugh but he managed to remove the tail that helped it self right and bent most of the bolts that held the lifter together and also chewed the angle round the sides and put a nice dent above one of they eyes and knocked a spike off, surprisingly they both still work fine and i think i will upgrade scruffy and build scruffy 2

night fury has chewed angle steel down the side and a few chew marks in the 8mm nothing managed to get through, lost 1 of my meet spikes to drumroll


in all the robots required better drivers and a few mods

[plargen]

done a minor mod to night fury ive have replace the Dean link for a xt60 in the hope it will not fall out and im also going to test a 3s lipo at the colchester event to see if it makes it easier to drive as it will only loose about 1 mph and it had plenty of speed at the gsl

second i cannot decide whether to retire scruffy and just use its parts to build scruffy 2 or whether to make a few mods and keep fighting it

[daveimi]

Keep fighting it, the robots that are awesome seem to have been developed over a few years rather than totally re-designed.

[Eventorizon]

I would keep it and get it running again to use at non competition events. Perhaps tweak it so that you can have a battery that you won't have to charge all day so that you don't have to worry about bringing extra kit. Its nice to have a simple machine that you can just drive.
Stupidly neither of our machines are like that so the 3rd robot design we're going to do will be a non-spinner.

[plargen]

well it still drive ok and the lifter works it was just the fuse connection and the link that gave me problems, but i was thinking of re designing how the lifter moves so it can self rite with out the tail and spikes and i suppose if i give it a bit less ground clearance at the back it might give it a better chance but im still intending to do scruffy 2 as i think ive spotted most of the flaws in the original but the shape will remain similar and i will keep they eyes and spikes (its main character)

[plargen]

ok scruffy 2 has now been started, it will be wider with a lower profile, but i'm still keeping the design of the head/lifter with the eyes and spikes and i'm also keeping it a similar shape

the lifter will be different at the front as the previous one was just a piece of 5mm mild steel which bent to easily and it wont require the tail and spikes at the back to self right

[plargen]

removed scruffys lifter and stuck it on top of scruffy 2 to see what it might look like, there will be more spikes on top of the new one and the front of the lifter will be more of a structure than the flat piece of steel at the mo

also looking at going for ti for the top panels

[plargen]

very hot today but i manage to do a bit more to scruffy, i think its starting to look like mr happy



and i've ordered the gimson actuator so it will be allot faster than scruffy 1s

[harry hills]

Sweet, I think Scruffy will do pretty well in competitions in the future. Awesome skills mate

[SamO]

This is looking realy realy good!
Did you decide whether or not to use Makitas?
I would highly recomend them

[plargen]

ive got some makitas but they are going in a grabber im building for now i will stick with the ryobi 1s i used in scruffy and night fury, they gave me no problems and lots of speed/power

which makita drill did you go for ?, i got 4 of the 6281d so estimated to speed of about 15mph in high gear

also the chassis has been a pain to make with all the angle and trying to keep the weight down is difficult but it will look like a more evil version of the original scruffy, more spikes etc...

[SamO]

I'm not sure, will have to check on the outer case of the drill, but its out side in the garage at the mo.
I'll find out for you tommorow

[Ellis]

Looking really good. Scruffy took some serious abuse and seemed very reliable. I agree with Harry, I think this is going to be a solid competitor.

[SamO]

Here you go: 6281D 14.4v
The same as yours
