I’m not saying that I’d actually do it, most likely it would be too fast to be controllable. I was more indicating that there probably should be some restrictions.
I bring official information,
The competition has now been changed to Underdrive. Same comp. different name.
The cost will be $50 per robot. Teams can enter unlimited amount of robots as long as they pay.
Mister T guessed em, the dimensions are 10 by 13 by 20.
As far as restrictions are concerned, there will be none. We have talked it over and it will make the competition more interesting when we see what teams will be able do with different materials.
As for game rules, please refer to the overdrive rules.
Finally, we need a set up a date. Please let me know what month will be comfortable.
we are looking at roughly November. mid to late november. let me know what you are comfortable with.
Encourage other teams to participate in this event. We want to have fun and make this event really exciting.
So what are you going to use as the track ball playing piece?
will this be the championship rules or IRI rules? (read the thread on chief delphi about rules changes, mostly concerning g22)
Ah yes, great question. We are looking into kick ball shapes to meet this need. We will be using either a generic 10" kickball or a 14" kickball. Information will be updated very SOON.
Umm…I’m not familiar with the rule change. I guess championship rules.
Yes it will be championship rules.
ALSO: We are open to trackball suggestions. Preferably something which is a little bit bigger than 13" in diameter. If any of you know of something, thank you.
I would say use some kickballs.
Wow Thank you. I will check with my mentors and let you guys know what the ball type will be very soon.
Watch MiniDrive/UnderDrive “accidentally” be next year’s competition (except with all the restrictions)
I also think there should be some scaled down versions of the ABU Robotics competitions (They’re really amazing with Autonomous robots and Tele-Op robots working simultaneously; I think there were some videos on YouTube, too)
How big is the field? How high is the overpass? What is the driving surface? Any restrictions on operator interfaces or onboard computers? Can we use hydraulics? How about internal combustion engines? Can I run 5000psi compressed air on board? How about size after start – can my robot expand past the starting size?
Oh fun! A small bomb on wheels.
Dear Rick TYler,
Good questions.
The field dimensions and sizes are exactly 1/3 scale, as is everything in the competition. The following link takes you to the official drawings of the Overdrive field. Just take everything and divide by 3. Also, the rack is 6.5 feet high. I don’t think the drawing mentions it.
No restrictions to anything on the robot. If you manage an internal combustion engine, I will personally come down and shake your hand, :D. Pneumatics, go for it. But the 5000 psi, can be a little bit dangerous, and remember robots that are deemed dangerous to other robots are illegal.
Of course, and once again there is no limit to how far, but as official overdrive rules state, you can’t block traffic for more than five seconds unless hurdling.
have you read and considered these? they really make sense if you think about them:
Were these the IRI rules you were referring to?
If so I am in full support of these rules.
I am writing a rulebook in which i have mentioned some of the changes.
I will be sure to ad these rules.
Ok, so around 9"x13"x20" (if you round) and 40 lb.
I say a gas engine would not be a good idea since its very impractical. I say a robot that is mostly made of VEX parts and maybe a shooter will do best.
I’m interested in seeing a mini-simbotics bot (simbotics FRC was undeniably the best performing robot this year). Someone take pics/vid of the event please!
Thats what I am planning on building if I do this.
The problem would be getting the power to punch the ball.
the official dimensions are 10x13x20.
And about weight…hmm…i’ll see if we implement weight. i’m not sure if we are.
Small strip of surgical tubing and a geared down VEX motor would do the trick. I would also use a servo motor to “hold” the axle down and suddenly release the piston to punch the ball. I have a half-baked design for it in my head, but I’m too busy to build it =\
