hi theekshana

do you have a pic from your ARC?what are you using ez-b4 ?

i made some pics.

the question mark( ? ) explain how to use it.all has these.

Thx for the pics and yes I am using ez-b 4

am a newbie to.

do you use servo's from ez ? try one servo and see what it does. is the ez-b4 allreddy connected to your pc or?

I wanna be able to use the arrow keys to control it.

am not sure about the arrows keys how to use it.but i do know there is a , wireless remote control. someone will chime in chortly,for technical details.

think i just found it.

here the link how to do it.

arrow keys

A Movement Panel will react to the arrow keys, no need for the keyboard control @nomad18.08 pointed you to. The question is which Movement Panel you need, and that depends on the hardware you are trying to drive.

Since you said Rideable, I assume you don't really mean servos, but motors, so you will need H-bridge(s) for the motors. An H-Bridge or Sabertooth Movement Panel can drive a pair of motors, using differential speed for turning (one motor turns faster than the other, or at the extreme, one goes backwards and the other forwards for a turn). However, since you are talking about 6 wheels with only two steering, you will probably need to script your actions using a custom Movement Panel (although you could have an h-bridge Movement Panel driving the front motors, and then script movement of the 4 drive motors based on what the front motors are doing.

But how do you plan to steer a 6 motor device with only the front two steering? Are you going to do differential steering on those (would be difficult unless you do differential steering on all 6 wheels), or some kind of steering wheel that turns the motors. Depending on their size, you might be able to use heavy duty servos to turn a steering wheel or other device, or you could do something with a motor, like a worm gear motor and a gear on the steering shaft to kind of make a rack and pinion type device.

I am not really trying to answer your question here, or scare you away with too much technical detail. Really just pointing out that we need to know much more detail about what you are trying to build, and what hardware you already have before we can answer any questions.

Assuming you bought a developer kit, I would first build a boxbot using a Movement Panel and the continuous rotation servos that come in the kit. (just use some hot melt glue to attach them to the bottom of a cardboard box). Add some cardboard arms with the other servos in the kit to learn to control them, etc. basically, get to know the software and the basics before jumping into a big ride-able build.

thtechguru thank you for chimming in. is that any movement panel?
