Re: pic: It's So Small, It Only Needs One Person

48 pounds is great...but you guys definitely got up on 2 wheels quite a few times...have you considered adding weigh to your base for lower CG and better traction ?

Re: pic: It's So Small, It Only Needs One Person

Ballast would give a lower CG, better traction...and less acceleration. I didn't see anyone mention Orion actually tipping over; it sounds like 102 made an effective tradeoff.

102 actually tipped over in a few rounds, a couple times for line violations,

One match in particular that I found funny (sorry 102) was when they tipped over against the driver station and they tried using the plunger to push themselves back up, but the plunger got stuck.

Did you watch them in action?

Yes their acceleration woudl be hindered slightly, but if they didn't have to come to almost a complete stop at each corner I think they're overall lap time would jump greatly. Watch one of their matches...they have such potential, I just saw the tippiness they experienced as one of the few weaknesses....

Re: pic: It's So Small, It Only Needs One Person

To answer any questions about Orion...

It is 18" by 16"
It weighs 48.2 pounds, as George said, with bumpers and battery
It goes 27 fps... yes... 27 feet per second... (geared for 30fps) one reason why you see it fly.
We have 4 mechanum wheels... after a few practice matches they disable the use of the strifing of the wheels because our driver found it eaiser to just drift into the corners and keep it up and still have the speed.

Our driver is PHENOMINAL at keeping it upright. A few times we did tip mostly because we were knocked off balance due to hitting a robot at full speed or being hit by another robot carrying a ball. And yes George, that one time it did tip... it was funny to try to see them get it back up. I didn't know why they couldn't until you pointed it out. Thanks!!!

And thank you to everyone who is saying things bout this lil robot I am passing it along to my team and especially my engineers. We had a great showing at the NJ Regional (got onto the 4th alliance) and are ready for our next regional at the end of the month. Hopefully you will follow Orion through the season and we really hope to get to Atlanta and put on a great show there Keep an eye on us... or at least try to haha
