how did you attach the FP motor to the shaft? my team is working on attaching one for our picker-upper.

thanks

Looks like they used a piece of PVC pipe and cut slots in the end of it.

Out of curiosity, how well does the Window motor powered belt work? We'll have one assembled with that motor by the end of the weekend, I'm just curious if it's fast enough in practice (our math said it is).

Re: pic: View of our Harvester 842
 

Depends on what you define to be "fast enough". The Denso motor has a free speed of 84 rpm's. If we assume the rollers will run at that speed (ignoring friction in the system), with a 2 inch diameter roller, and belt on both sides (ie sandwiching the ball), thats a travel rate of about 8.8 inches per second. For our system specifically, this simply isn't fast enough for us to be competitive, but every design is different. Looks great 842! Teams like you and 1726 should get special recognition for the openness you both have with your design process.

PS. I realize you did get the 2008 Chairmans Award, which is pretty good i guess :rolleyes: , but maybe a ribbon or something would be nice as well...

congrats.

nice we have a similar pvc wheel design. bu we are using a piston to get the balls to the top of our system.

that bot looks really cool from the front.

Re: pic: View of our Harvester 842
 

That looks like a clean design. How does it work with multiple balls in the chute? We were worried about rolling the balls against each other and having the straps on the balls catch on each other.

Looks good, have you done any tests?

Is that chassis really legal? You might make the 2/3 rule, but certainly there's a rule that every corner must be protected by bumpers (at least 6 inches) on each of the corner, right?

Re: pic: View of our Harvester 842
 

All:

There are already numerous debates and threads and posts about the bumpers on 842. This thread is about the harvester.

Please refrain from commenting on their need for bumpers.

Thanks -

Haha, they most definitely know this by now. I believe they plan to install flat front faces on both sides in order to mount bumpers on them.
