Ignore the mess of tubing at the back, we just haven’t got round to tidying it up yet.

I want to see it fully extended! looks like a busy robot.

3

Looks good! Need more pictures though!

Interesting. Andrew Is confused.

5

Andrew from AURA is also confused, but that’s mainly because I’m trying to program this thing at the moment.

Oh and it’s a high school robot (i.e. it follows high school rules).

6

See the Green gear? Count the number of motors attached…
I wonder what this is attached to???

Hollly crap; looks like planetary gearing. o.O This is one crazy “prototype”…

~Jordan

P.S. Nice work. :stuck_out_tongue_winking_eye:

8

a hang mechanism =D
oh wait, wrong competition :stuck_out_tongue:
looks good (and confusing)

9

As far as we know, there’s no rule preventing you from climbing the gate when it is in the up position…

10

That would be pointlessly silly… :stuck_out_tongue:

11

yet pointlessly awesome :stuck_out_tongue:

12

hehe, i kind of get this…
very interesting, i would love to see more of this.

Almost half way down the second page before a sepcs request? We are slacking!

I’m liking the concept you have going, or at least what I think it is. I do have a few questions about it, so I’ll describe my guess so you know where I’m coming from. Your conveyor picks up and stores your scoring objects, then lifts them up to your claw, which is angled lower into place by that pneumatic cylinder. When you’re ready to score, the claw moves along the rail of chain you have along the arm it’s attached to. Putting the cylinder back up seems like it would put you in position to score on the 20 inch goals.
Based on all of that, I can’t imagine you’re using that many motors to power a slide system. That means that your transmission picture goes to your drive train, I’m guessing with a speed up to get the ratio you want.

All that being said, is this robot going to be able to score in the 30" goals eventually? Can it only score one piece at a time? How reliable is it on the shorter goals if you’re dropping pieces from a distance(The height of your conveyor I’m assuming)? The only red I see on it so far is the barrel, do you have plans for any sensors?

Keep up the good work!

14

Not a bad guess!
Firstly, yes this robot can score 30 inches :wink: and also yes, you are right that all the motors in the cluster are for our drive. Currently we only have potentiometers and shaft encoders, but this will change when we start writing autonomous (i hope!).

We will probably do a full reveal if this robot ends up competing in the Robot World Cup!

15

I do have to commend you guys on using planetary gearing on the drive, maximizing use of motors to have a powerful drive, and using pneumatics on the arm and the claw to both store and score pieces. If i may, i do have two questions. One, how is the arm able to extend if the sprocket in the back part of the robot is stationary, and mounted to the piston? Second, are the planetary gears only controlling the drive, or much more? :wink:

Thanks.

Hi Matt;

I think you guys are missing something on the lift; have a closer look :wink:

And the gears are only for the drive! Nothing like being able to push the furniture around the room you are building in :stuck_out_tongue:

17

Again my head hurts… Is this my VEX noobieness kicking in here? I dont see how it works!!! Lol :stuck_out_tongue:

Hey,

I love the robot it looks awesome. I have a couple of questions:

Is this both a interaction and isolation zone robot? If not Which one?:slight_smile:

What is the red Barrel Doing on top?:slight_smile:

Whats the ratio on the drive? Fast or Slow?:slight_smile:

And how does it lift?:slight_smile:

Thanks in advance

  • This is an interaction robot, based on high school rules (i.e. only 10 motors).
  • There is a scoring mechanism on the top, which is why the red barrel is there.
  • Only some parts of it lift. Not as much of it lifts as you might expect.
  • Also a couple of people have talked about our planetary gearing. It’s not.
  • We don’t have a transmission system on our drive. It is very fast, and also has very high torque. In the development of that drivetrain, we twisted one axle, broke a 32-tooth sprocket, deformed a 12-tooth metal pinion, snapped two 1" standoffs, and put a 269-motor out of commission:

That’s intense.

How many motors do you have on the drivetrain?
