How To Control A Ez-Robot Over The Net With A Cell Phone Wifi Hot Spot?

Skip to comments   Jump To End

What is the best way to control a ez-robot over the net with a cell phone wifi hot spot? Basically I want to control my robot remotely without having a computer with Bluetooth near it.

If it is absolutely not possible what do you recommend for a bare bones computer? I would want it to be small and cheap. All I would use it for is a to run ez-robot software so I could access my bot remotely.

Thanks in advance.

You could have a mini.itx computer in your bot and remotely control it.through a web.interface

Hi herb191,

ARC needs a COMport connection to work. As you know it comes with Bluetooth. You must have a Bluetooth dongle connected to a computer that is physically located in/on or near your robot. Within 30 feet or so has been my experience..I think EZ-B has a Class II BT board on it if i am not mistaken.

This has limitations as you must have a Windows PC/Windows Tablet near your robot.

There are several other solutions folks in this forum are using to extend the range of their EZ-B to computer connection. XBEE and Synapse are two companies that make wireless serial data radios that can be hooked up to extend the range of the PC to EZ-B.

An alternative I am working on (as soon as my parts come in)will be a WIFI module that will replace the Bluetooth board on the EZ-B. With this solution, you install a virtual COM port through software on the ARC PC that uses TCP/IP to communicate with the WIFI module on the EZ-B. Theoretically this would allow you to run ARC anywhere in the world and control it from any computer so long as you have everything setup (Internet Connectivity, port forwarding on your router, etc). We shall see what happens with this.

Also, if you look at some of the great things DJ has included in ARC you can control one session of ARC with another session via TCP/IP OR you can run ARC as an http server and control the EZ-B through a web browser, like one on your smartphone. Lots of options, but most of them do require a PC on scene within wireless range of your EZ-B with exception of the solution I am going to work on.....and as I said, that is theoretical.

The WIFI module I have on order is actually linked here on DJs site:

Hope this helps,

Good Luck
