Was this project ever completed? Did any one build similar to omnizero?

Ooh, pretty! That looks great Viking, Im very interested in how this project is going. With any luck, you'll be sending OmniZero home in a coffin

Just started designing my new bot and hopefully will get in the machine shop on monday to start machining.

How's you project coming along done anything else to it.

bracket patterns?

2006-09-05T19:53:38+01:00

It looks like those brackets could be made of laser-cut Lexan (e.g. by the good folks at Pololu), for those poor saps among us who don't have a CNC machine in our garage.

Any chance you could post drawings of the parts you have made so far? Maybe we could start a sort of open-source Robo-One project, based on parts that can be either bought or made with cutting services like this.

Best,
- Joe

Neat. That was the first time I've see him in action since the games. ...not the best performance, but...

It's true, he was a tad on the slow & unstable side. Both Tony and I were having balancing issues.

OK - that's the first time I see the Rook's Pawn do some move - hmmm a bit 'nervous' movements I guess 8O U see thats why I've falled in love with this OmniZero - he's a cool little raddish with floating moves.

Anyway I have desided to make the pivoting torso and also know how to approach it. Another thing is that I will ditch the RN-controller and instead use my SD21 with a Basic Stamp controller. I don't know about you but I find the RN-controller very sluggish! Meaning that you just can't expect it to do the moves smoothly!?
Also I have desided to place the batteries in the feet just as Matt do.

Right now i'm awaiting some more carbon fiber sheets to arrive before I can start mill the parts.

-See u

Hey,
I have a couple of videos that show the torso rotation okay. If you are interested in seeing them, here are the links.

Thanks guys!

I actually milled out a dreadfull fiece of junk last night supposing to be his torso but it ended up to look like a soccer player in a silver t-shirt. (because I used my "silver-carbon-hi-tech-very-expensive-sheet")
I even incorporated the body armor from RN-1 but still he looks like a joke 8O
I wont show you a picture ( yes it's THAT ugly) - I need to puzzle this out how he should look - I might go for a "Quasimodo look"you know like a heavy overbody hanging down with looong arms or perghaps (my favorit) the robot from robocop "We are goint to war" and he reply "WAAAR" with his half open steel jaws! Remember him?

Perhaps I should ask my wife to kick my butt and go for the "twist" - It's so nice when our love ones shows interest in our hobbies - isn't it Matt!?

Anyway I must be carefull not to rush the result because I'm getting closer to my next three month contract at sea - Perhaps I should spend those months to come up with some good ideas!!??

- see u

I have some footage of Rook's Pawn at the Robogames. I'll look through the videos and see if there are any parts that show the torso rotation well.

Here's a quick video of how the pivoting torso worked on the 1st rook's pawn... He was't quite complete here, but you'll get the idea.

I wish I had a better video to show ya... Hopefully I'll get the footage back from RoboGames soon.
You are right. It's a battle between wanting more room or the added movement.

I almost ditched the torso pivot deal, but my wife talked me back into it. Overall, I like the benefit of having it... it's just a hassle routing through tight pockets.

I think personally I would not do it, but you go with a bending torso, similar to the Cycloid robotis robot. That seems to have some very nice qualities. Although once again you will need to have the two body halves.

Dynamizer (who is one of my personal favorites) has the bending waist as well. Very effective in helping him get up. Believe it or not, he also has the pivoting torso too!

Well you will be using independant leg rotation, and from my brief expirementation with it it works pretty well. Matt has both now, and has a stronger servo for the twisting (i believe), but i dont know how much further motion it gives him because he can already twist like that.

But on the other hand it make for a good speed and you dont need to rotate the legs if you want to twist. I think personally I would not do it, but you go with a bending torso, similar to the Cycloid robotis robot. That seems to have some very nice qualities. Although once again you will need to have the two body halves.

Looks good thusfar, so I'm sure youll come up with something that meets that standard

Help needed

2006-08-28T17:35:42+01:00

Hi Guys

I need some help or suggestions here.

I'm a bit stuck here whether I should make the torso twistable or not. Problem is that making the body in two halfs will limit the space for batteries and controller.
If I keep the body in one piece I can make the bot smaller and fit all cables neatly while making two body halfs will make it much more difficult and congest the wireing etc.

What would you do? Is it worth all efford to have that 'twist' or not?
appriciate all comments.

p.s. without the twist I can add more electronics
