Since Singapore VEX is now over, and World VEX is in 9 months time, we would like to reveal one of our robots that took part in the competition.
Reveal video:
This robot has 2 methods of scoring, by reverse dumping the stars/cubes or by launching the stars/cubes with the catapult. The dumper is also used to lift stars onto the catapult tray in the robot.
Specifications:
Holonomic drivetrain
4 motors with internal speed gearing (1.6), direct drive
4 3.25’’ Omni-Wheels
Very cool! I’ve been looking into catapult/dumper bots, and you robot is a shining example of one. My question is, can you robot score cubes into the Far Zone? There were times when it appears that you could, but you didn’t. I don’t want to make any assumptions though. Very good robot this early in the season!
The catapult can only score cubes to the near zone.
As for scoring using reverse dump method, it can… but sometimes it really depends on how the cubes land on the tile - sometimes it might roll a bit or sometimes it just stay still. And it also depends on where is the position of the cube when they picked it up, ie. how far deep into the tray is the cube.
How often did the team use the catapult during the match? Was it roughly a 50-50 split between dumper and catapult, or was one preferred over the other?
As what I see, a catapult without anything but motors on a high speed gear ratio could shoot the stars full court with an insanely fast reload.
But that’s an insanely awesome robot! #HybridBots
Is it me or that’s a lot of lexan on your robot? Is that legal? -Just a little question, but nice bot!
To be honest, the catapult is the most useful during autonomous. During matches, it is really more convenient to just intake the stars and reverse dump.
but as you can see in that few snippets, the catapult is a good tool to have in your arsenal. It can catch the opponents by surprise, eg. just when they were trying to line up to block your reverse dump, you shoot the star across instead, etc.
What we did was that we always have the lexan cut up to pieces of 12"x24".
And the teams will always used one sheet of it that’s all. This is a very “safe” approach to ensure the teams will always stay within the legal limit
Both clawbots belong to 8068. And yes… they were awesome!
One thing I like about this season is that - there seem to have no obvious “winner” in terms of a winning design… or at least, I still couldnt figure out a design that will prove to be a sure winner. Both claw and tray have their pros and cons.
If I am budged enough… I might make a thread about our clawbot But I must say… This has happened to me twice in a year; I run as 8068 but with no communications during our working stages both 8068 and 8059 came up with a similar robot design. First it was the NBN programming skills robot(about that…), then now it is this catapult and dumper! Unfortunately scrapped it in the last few working hours to build the claw. Hmm…
