Looks very good ewan - seemed to work very well!
Only improvement i can think of would be to put some rollers towards the front of the robot so that it drives a little easier when youve grabbed some-one.
We found your wheel that little spinner took off when we packed the arena away :) did you want it back?
I saw that fly out and bounce under the arena, i assumed you picked it up, but guess not hence grant found it. LMAO!!! Was good fight thought.
Mr Stu
Cheers Jamie
Hmm front rollers, thats the thing with a one day build... you never get round to doing the little things (and you dont get any sleep! Im hopefully not doing that again any time soon, lol)
lol dont worry Grant, I knew it was under the arena, I saw it fly there as with Stu but had plenty of spares :) If you still have the wheel around I wouldnt mind you keeping it on the side till the next event :). Im looking forward to seeing your videos Grant!
All the best

Drum teeth are angled the wrong way, but otherwise a decent design to be starting with.

i just knocked it up for the robowars event. the drum never stops and it hits so freaking hard. had some slight build quality issues (XD such as the teeth bending cause the welding was garbage and the frame exploding itself).
drives didnt work properly so i need a new set. alas should be good when i fix her up for the next event with some A123 cells and that 5330 brushless .
btw ali, you need to pull those castors right up beside the drum. itll rock fowards non stop like that. and id give yourself more clearance on where the pulley goes.
Hmm, seems the time of the drumbots is here :)
Name: Drumroll
Drive: Two 9.6V drills @ 12V on to 100mm blue wheels
Controller: Two 50A Speed Controllers
Weapon: Drum (obviously! :P) driven by friction drive from a drill - keeping it simple for my first spinner - but will upgrade later once I have a better understanding of forces involved etc
Armour: Poly base, either hardox or ali sides, poly top and hardox slopey bit
Status: Designed (see profile) and currently sitting as a pile of parts (minus the drum)
Notes: Called Drumroll because its a drum....that rolls....plus Im a drummer - seemed fitting :)
Still need to work out the best way to manufacture the drum, and work out what bearings to use etc but it can easily function as a 2WD wedge/rambot until then.
Better get my drumbot finished or it may become out of date.

Its all dont minus wiring the weapon and getting suitable batteries and a charger.
Hopefully i can get it done and out on the circuit this year(touch wood and cross my fingers)
Jamie, You got mail.
+1>2007 : Year of the Drums
:mrgreen:
@Chris: Didnt spot the teeth on the drum - good call
@Glen : I didnt steal your idea i was mearly inspired :proud:. Will tell Tony to move the castors up closer and perhaps out a little bit to stop it tipping ? Dont quite get what you saying about the pulley though :S.
Im pretty happy about the design. Drums seems to be an area not explored really in the UK but there is now a sudden explosion of them :P. Im also happy about the aussie robot Reboot wining Robowars 4 cause its using the same 100 watt motor for the weapon that I am
Ill be honest and say I didnt think much of drumbots in the past. Then I came across Team Mad Cows website, read some reports and watched some vids and realised theyre actually pretty cool (and effective!) especially if all the factors (such as speed and strength) are spot on.
2007 : Year of the drums indeed :proud:
