ALI STOLE MY IDEA

Power: 1x 24v 2.4ah nicad pack.
Drive: 2 x 18v andrewmod drills @ 24v
Controller: IBC
Weapon: 5kg Drum spun by 100 watt scooter motor
Armour: 3mm ali top and bottom 6mm -12mm sides.
Status: Finished and had a go in the rumble at robowars 4
Notes: heaviest drum ive ever seen in a feather

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Better get my drumbot finished or it may become out of date.
Pic on Profile.
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


@Chris: Didnt spot the teeth on the drum - good call

@Glen : I didnt steal your idea i was mearly inspired . 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

humm.. really Conundrum came before Glen and co. but I wont admit its the first uk featherweight drum bot either. Its successor Conundrum Mk2 has a 2kg drum powered by an Ev Warrior, I tried going for bars at first but found they wasnt to my liking not enough damage and didnt really get the pop I wanted. No ive got four sets of sharp blades which are proving to be much better.

@Alistair : I was joking about the teeth, they are only facing the wrong way when the robot is inverted lol, if you look at the CAD then imagine the bot has been flipped over you should see there fine hehe!

@ Jamie : I was the same with Drumbots , thought that they were not that destructive . Then i see Team mad cow and Im like wow . Another good Drum bot is Helios made by http://www.teamcosmos.comwww.teamcosmos.com

@ Chris : I understand you now about the teeth lol . Have you got any pics of your bot ? Dont ever remeber seeing any.

Just a quick pic of the pile of parts lined up for Drumroll (minus the batts and drum):

Having just discovered that Technobots are shortly gonna be selling a new motor as a replacement for the feather gold, I might change to that to power the drum, because I dont see a friction drill motor cutting it in the arena much (perhaps in the cadet class but with Drumrolls chassis having hardox armour that kinda scuppers those plans)

DragonMaster
2 x 18v drill motors for drive.
1 24v 200w motors from tecnobots to drive the axe just geting the parts together. pic on profile.

Future Featherweight, donno when it will be finished:
http://i3.photobucket.com/albums/y89/Flippt/Accident20075.jpghttp://i3.photobucket.com/albums/y89...ident20075.jpg

18V drive and 2400mAh NICD sub-C cells.
still Unsure if Ill use a Hammerdrill motor or not for the weapon.

Armour; 5&10mm HDPE.
Weapon: 180mm diameter Hardox 650 disc, about 1:2 ratio.
Numbers of screws: Over 60 of them!
weight: (In CAD) ~11kg
Other notes: Its invertable, needs wedges, and one of the few Swedish Featherweights.

Well was just about to rebuild DragonStrike. I will leave it as is now. It would have looked like pic on profile.

Latest pic of what hornet 2 will look like on profile.

Weapon - 2kg vert disc powered by a 3hp magmotor
armour - 4mm ali and 5mm polycarb
drive - 18v motors overvolted to 24v
speedos - electronize and a victor for the mag
weight - no idea

It will get built no matter if there is an arena to hold it or not. Obviously I dont battle as often as many others on here so it is not a huge concern to me. Then again I built swarm when there was no arena to hold it and was told I was mad. It was still accepted into the UK champs, just a shame it never span
