A hey hey!
Sorry Joey, i kind of put Lil yellow taxi out of action with truant!


Anyways, i am planning my new BIPED FLEAWEIGHT, Stompy. He will be more of a fun project than a competetive bot. I think i have worked out all the mechanics, and his weapon will be a dremel saw blade, on his right arm, which is going to be able to move...

I am wondering one thing though. If you have an antweight cluster with 2 bots, and one is a walker and one is not, do they use the antweight walker weight class, the normal 150g, or does the walker have to be 112.5, and the wheeled bot 75???

ah, just found this:

2o) Where a clusterbot is composed of a rotary and a walking/shuffling botlet, then each botlet is allowed up to half the maximum of its class (e.g. an antweight cluster might be composed of a roller weighing 75g and a walker weighing 113g).

But, does that meant that if the walker is disabled, then the cluster loses the fight, because when i faced good and evil, i took out good, and because he was the heavier robot, he was more than 50% of the two combined. And if you disable over 50% of the cluster then they are out.

Here are some of the parts i am thinking of:
2x Solarbotics GM11 75.7:1 Sanyo Gear Motor for drive
1x ServoShop Sub Micro 3.7g Servo for the arm
Peter waller option b speedo
Ar6110e for rx
2x LiPo's (fullriver) for drive

For the leg system, i am going to mount a gear with 4 offset holes directly onto the motor. I then put a a leg loosely onot this, so it will not come off, but it can freely spin. The leg goes down through a tube which is loosley attatched to the body as before. this will give the leg an eliptical motion.
For the foot, i will make a disc from something, and put dycem on the base. I will then make 4 toes going all round the foot. These will be on hinges so that they will steady the robot when it is walking.

I probably need to put a pic up to explain it better...

Just thought I'd post a pic of my 10yr old flea,called Bruce.
I recently put new radio gear and upgraded the armour from 0.2mm plasticard,to 1mm polycarbonate,with a titanium edge!








It weight spot on 75g.
The weapon servo is an SD200,I cant remember what the drive servos were,but I removed the final output gear and directly attached lego shafts. It really shifts,(for a servo driven bot on 4.5V!).

Here is a link to a quick video too!!

That's actually really impressive, it's a really good robot

Are you planning on bringing it to an event someday?

[earthwormjim]

Thanks alot.
I am pleased you like it!
I built it for my son back in the day,and used it to chase his pull back robot wars toys around the living room!!!
I am thinking about ordering some geared motors and having a play,so you may see me around sometime!!

Hi jim

I have to say thats a very impressive looking robot, is the chassis milled out from a single block or is it bolted plates ? Its very neat inside, I'm really suprised you haven't been to an event before, and they fact you made a fleaweight on your first go

I have 2 fleas myself, Little Devil and Divinity, a lifter and a spinning blade respectively, they are running on gear-motors and were built to be a clusterbot to take on antweights as well as fight other fleas, hence they're rather overbuilt
