[FTC]: Early robot Testing


I call shenanigans :slight_smile:

That looks a bit off…is that real?

From what I remember of last years robot, they had a very accurate and consistent shooting mechanism. They might have been able to pull this off. Also, their shooter design, using a spring loaded arm, could probably be modified to do this. The one problem I see is that it looks like it might be violating the rules for a maximum shot of 10 feet horizontal and 4 feet vertical. :slight_smile:

The trajectory of the batons are off and tend to defy the 2 basic laws of projectile motion: 1. Constant y-axis acceleration and 2. Constant x-axis velocity(yes i’m ignoring air resistance…).

This is why a called shenanigans :]

i conquer…that third one looked like it a invisible air roof before coming back down. SHANANGANS

Very interesting video!

I have kind of a random question that was brought to mind by watching your video…

Our team built a practice field using FIRST’s low cost field perimeter plans and have found it to be too weak to use effectively. It is quite easy for a robot to push against the wall and move/bend it more than the competiton field. We were planning on just framing up some plywood to the correct dimensions to make a sturdier practice field. I noticed your team did the same in the video. We don’t want to over-do it and have the field be to heavy to transport for demos and the like, but we also don’t want to go to light and run into the same problem as before.

What thickness plywood did you use?
What dimension lumber did you use to frame?
Do you like your field, is it sturdy enough?
Any advice or pointers that you could give would be greatly appreciated!


I don’t know, that G-Force team is pretty sharp. They could probably rewrite those pesky laws of physics. Personally, I think all teams need to spend all of their time trying to copy this design :smiley:

As for the field wall question. I don’t know about 2818, but we built up a low cost field wall framed up with 1x4s and covered with hardboard. It works reasonably well and isn’t too heavy. The worst problem we ran into was getting the corners to stay together. As for flex, I have seen some competition fields with a lot of flex in the sides (more than there should be). Our design flexes, but it is not too bad.

How many of you looked at this video :cool: after viewing the baton launcher video? Anybody know who this team is and where they are located. FTC 72 Garagebots I’d like to know what future iterations look like for this drive-train.

Hello Andrew,

I am a mentor for this team and we have been working hard on delivering a new video of our updated drive train. It took several iterations to figure out the correct wheel spacing to make it over the mountain, but it now goes over. Currently we have pulled off the electronics to work on our arm/manipulator for the batons. Please feel free to subscribe to my channel on https://www.youtube.com/watch?v=(http://www.youtube.com/user/robodude03). We hope to have a new video posted soon.

Well let me clear everything up for you, first it is fake!
Kendrick made the batons in blender it took only 15 minuets to make also if you look closeup you can see that the first baton looks good then the 2nd spins slower and moves slower the 3rd spins the other way and the robot doesn’t move along with other things, I just wanted to point that out, he made it the first week the game came out and he didn’t have very much time to work on it so he posted it anyways. But it was a cool video :slight_smile:
