I didn't get any software instructions with it. Can you give me a link to download Arduino code for the 15001 3WD 48mm Omni Wheel Robot ?

I'm wanting to flip it upside down and put a ball on the 3 omni wheels. But I have no instructions at all or Arduino code. The end result I would like to do is to have the ability to input some numbers into several fields and have the ball move to each coordinate. Has anyone done this before?

I guess I posted this in the wrong part of the forum but I don't know how to move it. So you are supposed to use the forum for customer service/Tech support? This is my first robot project and I have no idea how to begin without some kind of instructions and code. It's and to believe that this kit wouldn't come with some kind of instructions other than how to attach the wheels.

We've moved this over to the correct forum category.

The kit doesn't include any electronics, therefore no sample code.

Interesting application.. not sure really. It's likely quite a bit easier to use two degrees of freedom. We have not sold a product like that, nor have we done one internally. Google's your best friend here.

Yes. Our apologies for the delay. We have moved it to the right category.

It sounds like a custom project, and the product you purchased is really only a frame and motors. Since there is no microcontroller nor motor controller as part of the kit, the manufacturer can't really provide sample code. Arduino is popular, but there's no requirement that manufacturers provide code for basic propulsion platforms.

Do you mean how to attach the hub to the shaft of the motor, or how to attach the motor to a motor controller? The wheels should be pretty straightforward to attach - the hub goes through the wheel, and the screw fixes it in place and tightens the hub to the wheel.

Since this is my first project I'm not sure about the motors. I've google stepping motors and it says I need to know if its a Unipolor or Bipolar. The wires look like they have a printed code on them, but I don't know what the dashes mean. Here's a question to everyone on the forum. Has anyone used one of these kits? What other component do I need to get this robot moving? I do have a Adrunio Mega board. Any help would be awesome.

The motors used on the 51001 (RB-Nex-11) are not stepper motors - they are DC gear motors with rear encoder. You need a compatible DC motor controller and a normal microcontroller. The manufacturer has the following suggestions:

https://www.robotshop.com/en/io-expansi ... o-v12.html
Combined, these can control up to four DC motors.

If you are using a MEGA board, there are no evident DC motor controller shields for four motors which are MEGA compatible (you'd need to read through the spec sheets).

You can always wire one separately.

For more information as to what's needed for a custom mobile robot, the following series of articles should help:
