How many motors are you thinking youll use?

[Jon Stratis]

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.

[Dr Theta]

We are looking at 9-10.

[KennyLives]

Somewhere in the range of 8-10. 8 is not too many.

And that's why we're only using 21.

14 motors. It shall be glorious, noisy, and likely the bane of our battery charger. Some may be powered through relays to free up motor controllers.

4 CIMs - Drivetrain
2 775s - Shooter
2 FPs - Elevator
2 Windows - Turret pitch and yaw
2 550s - Ball staging and pre-shoot spin up
1 Van Door - Bridge tipper

13 in total, so far. Might end up being 14 with the addition of a third 550.

[AllenGregoryIV]

4 - CIMs for the Drive
2 - 550s or 775s (if we risk it) for the collector/elevator
2 - FP in a CIM-sim for the shooter
1- Window motor for shooter angle adjustment
1- Van door motor for the bridge device

10 in total. (The van door motor will probably be on a spike)

The teams that aren't listing a motor for the bridge are you using pneumatics, not going for the bridge, or have some form of passive bridge tipping system?

[Aren_Hill]

actually at 15, heard of a team using 19

[Grim Tuesday]

4 CIM- drive
4 BB550's-Shooter
2 FP's-collector

10

We're using pneumatics to control our bridge actuator.

[MrForbes]

hmmm....

4 drive
1 fp shooter
1 fp collector/conveyor
1 AM gearmotor turret
I compressor

I sure hope that's all we need...

[Kevin Sevcik]

Oh why not...

4 CIMs on drive
2 FPs shooter
2 RS-550s conveyor
1 PG71 (new AM gearmotor) deploying the bridge wedge/platform
possibly 1 PG71 or window on shooter angle


Comments on some earlier posts:

There is, in fact, a practical limit of 30 (servos + Vex motors) since you only have 20 possible PWMs on 2 sidecars.

Similarly, there' only so many motors you can put on your robot. Or, at least, only so many speed controllers. At $110 each past the first 4, they start taking a significant chunk out of your budget. I realize not everything needs a Jaguar, but still, that 19 motor team is blowing a lot of budget just on motor controllers. Not to mention whatever they're using for gearboxes or couplings or what have you....
