LIFT VS. LAUNCH

No need to be despondent. Keep that mental image in mind, but just make one minor adjustment. You started toward this scenario in your first message, but stopped short of fully developing it. Think about your "bucket brigade" of robots handing off the Trackball from one to the other by temporarily storing it atop the Overpass. But make the process faster. Rather than slowing down the process when the Trackball is stored on the Overpass, make Hurdling the part of the process with the highest-velocity Trackball movement. Rather than three well-coordinated, excellent "Super Lifters" you need three well-coordinated "Launcher/Catchers." Then your original scenario becomes:

Robot A is positioned on the far side of the finish line, ready to catch a Trackball.

Robot B approaches the near side of the Overpass, and launches the Trackball in a spectacular fashion. The Trackball describes a perfect parabolic arc over the Overpass as it heads toward Robot A (if you are thinking about this correctly, you should have a nice mental image of Max the dog in "The Grinch Who Stole Christmas," waiting outside the house for the Grinch to throw the massive bag of toys down to him from the rooftop after stealing them all from Whoville).

Robot C is doing a lap with a Trackball in possession.

Robot A catches the descending Trackball before it ever touches the ground in its whizz-bang-super-combination-Trackball-basket-and-catapult-launcher (it's a dessert topping! it's a floor wax!). The crowd goes wild! The Hurdle is complete, and the robot proceeds to do a lap.

Robot B crosses the Finish Line (completing a lap), and turns around - ready to catch the next Trackball as Robot C approaches and launches it.

Repeat until you win.


That is the ultimate "dream match" that I long to see. If not during the season, maybe we will see it at IRI.

Wow, you must be looking at our design drawings! (is that why we posted them?)

The ball catching stuff looks to be fun....we can't wait....

Why, as a matter of fact we had a team meeting on Monday to discuss the problems with the arm (80" limit, mostly), the crossing the plane when you take it off from the back, and to revisit some of our earlier ideas.

Tonight we had a prototype pneumatic launcher in the works and are looking at how to launch (and catch) the ball effectively.

If even two robots can do this working together they are going to do well. They should be able to lap almost as fast as the "racers", at least as fast as the herders, and will be pulling in hurdles all over the place.

I'll keep my eyes open for a match like that.

I would love to see 3 launchers on a team, but i don't think that it will happen, i think the most you will see is 2 on a team. (Especially with the serpentine draft)
And i want to see how well and fast these robots can launch the ball over effectively and still be as fast as a lapper. With my calculations a GOOD lapper can do a lap in 10s or less. A launcher with a GOOD launch/catcher will be 17s+ and a hurdler will be 24s+ (Just my rough estimates.) So i would like to see all of the strategies teams will come up with during the season.

How would you plan on loading your catapult?
