four wheel steering using S3003 servos
Four wheel steering
I want to build a robot 4 wheel drive and 4 wheel steering and use Futaba S3003 servos I would appreciate to hear from people how worked on this kind of project before. Any information would be welcome. Thanks Hank

Next level up would be a 'front wheel steering' approach -- with two drive wheels in the rear, and a non-modified servo in front to position the 'steer'ed wheels. I've done this in Mindstorms, the control is a bit more tricky, because you no longer can turn in your own width like a differential steered bot. Instead you have to do 'y' turns like an automobile.
Next level up is 'front wheel drive' steering. Here you start to run out of room. You need some kind of flexible drive shaft, or universal joint. This is because the driven wheel has to be able to change direction. So you also need some kind of 'steering bar' to get the steering control.
Then we finally reach your "all 4 wheels steered AND driven". This is so complicated, I've never seen it done on the hobby level. If you could steer the front wheels as a pair, and the rear wheels as a pair, would that be sufficient? Maybe Tamiya has some hobby level gear you could use.

Below is a link to my webpage that has some information about it....If you want to know more that isn't on there, I'll be happy to answer questions.

with this set up the bot can make an L shaped turn.
