Scrambler B

[dragonfruit35]

I'm a little confused by the bucket that's supposed to be in the center of the track's length.

I do know it is supposed to be in the middle of the track's variable length, meaning, the run distance, but is the bucket also in the middle of the track's 2 meter width?
Does the bucket entail a bonus if we go around it, or is it a mandatory component of the track, so that all competitors will have to steer around it? Finally, if it is an optional bucket bonus, similar to Air Trajectory's bucket shot (aahh, Air Trajectory), would the bucket be removed if not being attempted?

And finally, how would you guys go about curving around the bucket? I'm curious to see how one would do that, and accurately stop at the center of the TB.

I did Wheeled Vehicle in 2015, and you had to go around a bucket in that too. Based on that and having read over this year's Scrambler rules:
-Yes, the bucket will be in the center of the 2 meter width.
-There is no bonus for the bucket- if you didn't get around it, you wouldn't hit 8.5 meters, thus you'd have a Failed Run.
-The bucket is a mandatory component and will not be removed.

Also, when I did Wheeled Vehicle, we made an adjustable attachment for one side of the front axle and set it at an angle that allowed it to curve back when started at a certain angle determined through testing. Of course, some of this would be different due to the nature of the launch of the ETV (externally) as opposed to that of a Wheeled Vehicle (from in the vehicle).

Hope I helped. If I'm wrong, feel free to correct me

Back again with another question...
How would we get our ETV to curve such as in this video? I tried using a search function on previous Scrambler threads and found something like this, so would you make adjustable wheel angle things for the front axle, the brakes on the back axle, and tilt your energy propulsion system?

You wouldn't necessarily need to tilt your propulsion system so much as the launcher itself the way I'm thinking about it. Or simply the ETV within the launcher...

The diagram shows an approach that is unnecessarily complex. Here are pictures of the vehicle in the video: http://scioly.club/archive/interlake/im ... scrambler/.

The design of the unit and car are extremely well thought out. Also very nicely built.

Thank you for the many photos!
I'm unfortunately still a little lost on how the launcher works, how it launches the ETV, what the purpose of the archery release is and where it should be clipped onto, and which rubber band or fishing line leads where and where all the fishing line and hooks (pulleys) are, given that this is my first year doing this event and I'm pretty lost could anyone explain it to me? Sorry & thanks.

Edit: I kinda gathered that the mass falls stretching the rubber band, which then falls onto the other rubber band on the trigger of the archery release causing it to let go. However I'm pretty much lost after that.

It appears to me that this design, from a prior year, would not meet this year's rules, which say the device must "use the energy from a falling mass to transport an egg along a track". And "All energy used to propel the ETV must come from a falling mass"

In the video and pictures, it appears that only the stretched rubber band is propelling the ETV. The band is stretched when the ETV is "backed into " the launcher, then held in place by the archery release. The falling mass, in this design, is only triggering the archery release.

This design, however, could be modified to to eliminate the rubber band and release , and have the falling mass pull the string and launch the ETV.

reed303, that rule was in place when I competed. Perhaps it's not clear from just pictures: the mass does in fact stretch the rubber as it falls, with the rubber originally starting unstretched. It is clearly demonstrated in this video: https://www.youtube.com/watch?v=HKisLACH9fU.

OK, I think I've got it! Thank you so so much
One last question. In this video the falling mass is cut off so we can only see the rubber band, and the video begins with the rubber band taut. Was it simply because the beginning slack rubber band was cut out or does the rubber band start off stretched?

For some runs I started with the mass at the bottom and triggered the bow release by hand because I didn't like dropping the mass every time.
