Forward and Right Steering

[dolittle]

Hi,

My son has this RC car which a very simple car.

To avoid making it "complex" by going it forward steering, the car steers by going in reverse (turns right around its center axle).

Has anyone done this in a Technic Model?

I think it would be useful for those cases when you have just one remote/one motor, or you are just looking into using that RC channel for something else.

Thanks,

Noam

It was done in code pilot as far as I know. A simple 24 tooth clutch gear can do the job.

Hi,

You mean set 8479?

Thanks,

Yup. Check out the instructions for the car. I think there is also something similar in the RIS Mindstorms 2.0 instructions.

Have a look at Philo's Killer Dozers. They use the same technique to drive and turn with a single motor. (and they are a lot of fun to play with!

There era also a couple of ideas in Tora no Maki.

Interesting, the idea he is to use a clutch element to make the wheel work in one direction but not the other, right?

Thanks,

It has already been introduced in this set- 8472

By hitting the bumper the car changes the direction and steers when going reverse. After another hit to the bumper it goes straight forward. Great and very underrated set, although the block with motor is way too big and I did not find any place for it in any of my MOCs.

A while ago I tried to do something along the same lines with mechanical automation. It drives forward until it hits an obstacle, then reverses and turns for a set distance, then goes forward again...

Hi,

How did you make the wheels go straight forward, but rotate when going back?

Thanks,

The power comes from the moveable wheel at the front. It is oriented straight when going forwards, but at an angle when going back...

Hi aeh5040, I like your build, but I can't seem to figure out how you did the switching between driving and turning and then driving again. Any change you have more photo's or some explanation.

To add something to the discussion, I will try to make a small movie of a "car" (it has wheels) I recently put together, based on the driving crane in the 8888 ideabook. It goes forward, backward, left and right using one motor and "cards" with Technic Gear Racks 1 x 4. I would like to use some kind of mechanical switching to reverse my card reading system.

Yes, that's how it works. There are building instructions for the Killer Dozers so you can easily make a copy and see how it works.
