Motors for harvester

[midway78224]

After the season has finish our team wants to make some changes to our robot. We were using a cim on our harvester but want to try out a new way to power it. So we wondering if any team can let us know how they power their harvester like what motor, gear ratio any information is helpful. Thanks.

We used an Andymark Gearmotor dircetly driven to our rollers. We found that it was a bit slow though, so we would reccomend a Banebots RS550 with a 26:1 gearbox.

we have some rs550 with 16:1 gear ratio do you think that will work.

We used a AM PG71 gearbox with a Banebot 550.

Did you have to modify anything to put the banebot motor on the gearbox.

Our intake roller and ball elevator were driven together, all by a BaneBots 550 through a 16:1 gearbox and a short chain run. The bottom roller was 2" originally; we did add tape between the grooves to build up their depth, so the effective diameter may have been bigger.

Was it fast or medium type speed our rollers are 2" with the roughtop tread between the polycord

Are initial fast-sucker stage was a 550 with a 16:1 and it worked perfectly with a 1.5 inch pvc roller direct driven.

Our vertical stage was a 550 with a 64:1 directly driven.

For lack of a proper measurement: Fast enough. We had to stop our elevator between shots for our shooter wheel to get back to speed.

Did you chain it or direct drive it. If chained did you run a 1:1 gear ratio

What's more important than the gear ratio is the linear speed of the contact point. That's the end all comparison really.

How can we get the best linear speed. Whats the best ball squeeze. We have a 2 inch squeeze although it work well for us we could never hold more then 2 balls because it would jam. Any suggest.

we used a 16:1 Banebots RS775 in our latest version roller that worked extremely well.

AndyMark sells a spacer to adapt the motor or you can shorten the output shaft. The spacer is easier. They also sell the gear you need.

Thanks we are trying different options to see what gives us the best result. Thank you for the information. I'll pass it on to our build team.
