That pretty much sums up my reaction to spiders Dave!

And today it got it.Quote:

I re-used some of the claw linkages from the old mechanism and trimmed them down a bit. I also had an M12 threaded rod actuator-type-thing that I got from Jonny (originally made by Billy Breach) so decided to fuse that with a drill motor to provide the motive source. A couple of bolts later and the basic setup was done:

Then it was time to put everything back together, fitting the existing components around the new ones (which don't take up too much internal space). So this is where it's currently at:

I need to redo the mounting points for the side armour, make some covers for the exposed drill motor and sort out a new top panel. The top will probably just be MDF with a bit of plastic re-inforcement here and there. Not got time to get more plastic delivered and it'd be a waste of money as I'm thinking of changing the design after the championships. The horizontal claws just aren't effective enough a weapon, and it requires quite a large robot to accommodate everything. So I will probably look more into a vertical crusher setup, but that's for another day...
Oh, and I threw a little video together to show the drive and claws, along with my standard ramblings:

About the best they've ever worked that :rofl:
Looks good, with more weight over the wheels with the full armour it might have a better shot at moving stuff around, but then again unless the opponent has conked out they'll probably be driving in the opposite direction from you when you've got them which might counteract that...
Should've added at the end that none of that will matter because the robot will be in the pit long before it needs to use the claws :lol:
Ain't nothing wrong with being hugged to death ;)
I'm thinking of going for a vertical crusher as well, but that's when I have more money to put towards it
That MDF robot weighs about 4kg at the moment, so I'm not holding out much hope of extra weight on my part improving matters!
True dat :proud:Quote:

will you add weight over the back wheels to make it have traction.when pulling other bots?
its very fast
No spinners is your draw for Carcinus?
Impressed you got it together so quickly.
Not sure if adding weight to the back will help much. The motors are just standard drills so they'd probably not be able to pull much against another robot trying to drive in the other direction. But I'll have a play about with things and see if I can improve it.
No spinners in the qualifiers, and I'm not expecting it to make it through to the latter stages. The sides are pretty well armoured though, if it does.
I didn't expect to get it done so quickly either, but glad I did as it leaves more time for other bits and pieces.
