Duel in the Dessert!

That looks more like 18 feet, not 18 inches.

You were totally over 18" as well as 18'! Looks like a great trajectory.

can you hit from say 14 feet to that? is that shot good from 18' to what short range? can you vary the shot?

no matter the answers, it's a wicked shot.

Dual in the Dessert!

So you got 2 Desserts?

Seriously, nice work and an excellent machine. Best of luck for the season.

It's good to see your shooter working well. I was in the pits all day, building a robot.

We finally got ours to behave today, with two mentors and some PVC pipe to adjust the angle. They claim it will get in the goal any distance from 5 feet to 20 feet, but they didn't have the goal set up. We'll see.

Cool, but it looks like the peak of your arc is significantly above the top of the goal. Do you have any way of avoiding the resulting "dead spot" in your range?

In terms of power, that looks pretty much exactly like our (4464's) pneumatic shooter; we're using four 1.5'' bore, 8'' stroke cylinders on ours, with the standard festo solenoids and a downstream tank for each cylinder.

In tests, we've been able to score from 33 ft. :D

Being able to shoot from 33 feet out is nice and all, but considering you can only score from, at max, 27 feet out...

A BALL is considered SCORED in an ALLIANCE’S GOAL if


a ROBOT causes one (1) of their ALLIANCE’S BALLS to cross completely and remain completely through the opening(s) of one (1) of their ALLIANCE’S GOALS without intervening human contact,
the ALLIANCE ROBOT last in contact with the BALL was entirely between the TRUSS and their ALLIANCE’S HIGH GOALS, and
the BALL is not in contact with any ROBOT from that ALLIANCE.


Emphasis mine

Looks very nice, but are you guys able to shoot from different distances? Because if you have that power when you're up closer, it will go way over. Food for thought.

842s robot can shoot with whatever power they program it to shoot with. Makes for a nice shot into the top of low goal.
