How does your robot hurdle?

[waialua359]

In addition to running around the track or herding, does your team plan on hurdling the ball? How?
We went with a quick pivot arm that grabs the ball from the ground, holds it on our bot, runs around the track, then lifts and hurdles the ball. Next, repeat steps all over again.
We also have the ability to knock balls off the overpass and place them at the end of matches also.

I have seen a lot of shooters/catapults which seem more effective. However, I am curious as to how they will place or remove balls from the overpass.

We're planning on lifting the trackball over the trellis, about halfway, and then dropping it over. We can also place it back on the trellis at the end of the match. Ours is a forklift device with a saucer shaped vacuum.

We have a flapper on the top if our mast that with springs will shoot the ball off o the overpass.

we currently have a double-jointed arm for lifting over, but are prototyping for a catapult to fire over the overpass.

Our 2 arms design have the capabilities of lifting the ball with 1 piston over, then dropping it on the other side.

[MrForbes]

We have a catapult shooter type robot, with a patent pending gizmo that knocks the ball off, and we've accidentally placed the ball on the overpass several times while testing the shooter.

We're using lots of electrical energy. About 500 watts to be exact.

How it gets converted to kinetic? Well, that my friend, is the cool part.

Our arm will be a hybrid between an elevator and 4-bar lift. It's in final construction stages now - pictures should be up soon.

So, are you looking to replace your arm, or design to have both? Wow!
**By the way, I think we were in the pit next to each other in NJ07 last year.**

quickly....

with force



Hopefully repeatedly and efficiently

( see ya next month!!)

Our machine will definitely have an arm capable of placing the ball and hurdling. Depending on weight and time there will be a shooter added to that arm.

I think you're thinking of 375 ^_^.

As for the arm/catapult decision...you'll have to wait and see .

Our team is using a pneumatic-operated catapult. However, to get the lever arm long enough we had to make our robot extend to twice it's starting size at the beginning of the match. The catapult arm will start raised at an angle, then drop down once the match starts.

Now I remember, the two-eyed camera robot of your 2007 robot.

We're using a catapult and a seperate knocker device mounted on the top of the catapult frame (so far) that will knock the ball off during hybrid mode. But other than really really accurate shooting we won't be able to place the ball back without help, hopefully we'll be able to hurdle fast enough to make up for it though.
