You will need to be more specific. Are you using a modified servo movement panel?

Yes

But only allows 1

also my wheels will not stay on the servos

You will need to use a long screw or a dab of hot glue to keep your wheels on the servos. While building a robot, there will be plenty of creative solutions to exercise your mind.

There is no native support for more than 1 modified servo per side.

As you are trying to do something custom, you'll need to dab into EZ-Script.

Use this example to demonstrate how it can be done: EZScript-Examples-MultipleModifiedMovementServos.EZB

My Test Bot runs 4 continuous servos. See the attached project for another example using a different method.

Thank you so much for your help folks

Oh smart Rich! Good idea to use the custom movement panel. I never thought of that. That's probably a better way than mine!

Also you could use a rc servo Y adapter on each side so two continuous servos get the same signal from one digital pin. Its basically paralleling and you can make your own Y cable with a piece of heat shrink and a bit of solder from two servo ext cables.

Of course I'm assuming you still want to use the basic right and left skid steering and forward/ reverse most robots use - Josh S
