Veronica can independently complete all defenses, gathers boulders, and shoots into the high goal!
The four-CIM, 8" Pneumatic drive on the AM14u3 KOP Chassis, blows all of the drivable defenses away while the motor-driven arms on the front and rear open the others!
Two sets of 2" wheeled collectors bring boulders into the robot, feeding them into a wheeled shooter aimed for the high goal.
Hanging/Scaling was our lowest priority after analyzing the scoring breakdown. There’s plenty of space and weight to add a climbing mechanism if we had had more time.
Not that Betsy’s answer wasn’t sufficient, but I’d like to add a “little” bit more detail.
We do not have a release mechanism currently. It’s more based driver instinct to not drive the ball into the shooter wheel at the moment. We experimented with a current sensor to try and find a difference in intake current, but had no luck (and little patience). A beam-break sensor would be ideal, but that’s for later addition.
Our shooting sweet spot is right in front of the tower, with wheels touching the BATTER (base of the tower). Ideally, we’d beat the defense to the spot and take away the chance of the defense blocking our shot. The video of us shooting from farther away was taken during prototyping. An issue we saw with shooting from a distance was the difference in compression between a fresh boulder and a used boulder, which affected shot performance.
Once again, probably the best Ri3D team. You guys have set the standard for a strong Stronghold robot. Do you have CAD for the bot you can post? I’m curious to see how you got that shooter crammed in there.
This question makes me want to run the math for the situation where the Shovel the fries™, is in the middle position to find the speed the robot would have to carry to make it to the bar…
Thanks. We’ll be posting a 3D pdf as well as some other resources, but not a full CAD.
Can you give some examples of how the wear affected shot performance? How much wear are we talking about?
That makes me nervous. 5254 and 20 haven’t tested with worn balls yet because both teams have only one ball right now.
If I was to guess, it was somewhere around 50 shots. We dialed in the prototype shooter until it worked with one ball, then we tried another ball, which flew completely over the goal.
The foam directly under the skin “crumples” slightly after many shots. You can feel the difference when you squish them by hand.
