How many motors are you thinking youll use?

So, how many? I know very few teams have solid plans yet, but what does your current idea require? Ours is looking to be 8 which i realize is pretty high, and it really worries me.

I would say some where between 7 and 10. 8 is not to bad when you consider what you need. Drive, Ball lifter of some kind, shooter / kicker.

Not using pneumatics is likely what will save us and allow us to do that many motors this year. Im glad our design is not completely out of the realistic range

In previous years, we have done both extremes between Motors and Pneumatics. This year, nothing is set in stone but I am looking at somewhere around or between 5 to 9 motors. Whether or not we use pneumatics this year is still up for toss.

In the kickoff presentation we heard we were allowed 22 motors and we figured that if we can have that many on it, mighters well make the robot fly, no rules against it so yeah, 22 motors it is :smiley:

7 motors right now, 1 of them being an extra placeholder just in there incase.

22 motors? Challenge Accepted.

We haven’t decided on our design, but a man can dream.

22 motors, ok, some small some large; they may be a strain on the single battery unless a large some of them are small motors or servos.

Kudos to the team that maxes out with 22 CIM, Window, BaneBots, and other largeish motors, then makes it throughout the whole round with no power problems.

The vex motor could spin a tiny flag around boosting your motor count.

Actually you can use an unlimited number of servos this year.

If I had my way, any unused motors would go towards frivolous tasks such as spinning pinwheels and running a continuous rube-goldberg-esque contraption that looks like its a functioning part of the robot but is really just confusing and does nothing productive.

Just because there are 22 to use and being ridiculous is fun :stuck_out_tongue:

But seriously, as few as possible. Speed controllers are expensive and I like to avoid frivolous power draw.

I’m thinking 8 or 9, 4 drive, one for the ball raising mechanism, either a motor or a pneumatic cylinder for elevation, and 2 for the launching mechanism, and likely one more for some ball sucker thingy.

the only problem is see with using 22 motors as soon as you get out of autonomous your out of power

4 CIMS on drivetrain.
1 window motor for floor loader.
2 FPs in a CIM-SIM for the launcher.
1 VEX 393 for the turret.

7 if we go with the much maligned 2-CIM drive setup, 9 if we go 4-CIM.

At this point, I think we’re thinking:

4 for drive
2 for the ball lifter/gatherer
2 for the shooter
1 for the turret

That could change once we get stuff built. For example, we might go up to 4 motors on the shooter, or add an extra motor on the lifter/gatherer. But, the good news is we finalized our overall design last night, so now we can stop prototyping and start working on specifics!

We’re looking at 9 and pneumatics. Ambitious.

Do you really think the VEX motor will spin your turret?
Remember the ratings on the spec sheets are for 7.2 volts…
I believe and please correct me if I am wrong…that they will be getting 5 volts from the digital side car… and not 7.2

They are tough little motors…and unlike the servos, they are continuous rotation so they could be geared but be careful of using the specs you are seeing on the tech spec sheet…those numbers are based on using the VEX battery (7.2 volts) which isn’t legal…I would think they would pull 5 volts from the digital side car…

Does anyone have an answer for this?

We are looking at around 11-12 motors.

We are looking at 9-10.
