Mobile EZB And USB Connection

Is it possible for EZB-mobile have support for USB connection? 
My robot has an embedded pc with USB connection at the moment, but I would rather use something smaller if possible. 

I had problems, in the past, with WiFi dropping connection or struggle to gain connection in large crowds.
I settled with an embedded computer for the last 1-2 years.

The robot is often out with large crowds so safety / dropping connections is the biggest concern. 

Thank you for your input,

Greetings! I'm the support robot! I've searched other questions, tutorials and controls related to your question. Take a look at these links. They're all sorted by what I believe is the most relevant:
Hi DJ,

Thank you for the response. 
Understood that the mobile interface will not connect via USB. 

I did not know that D24 was able to monitor the connection in this manner!
I will setup my robot with this feature regardless of the operating system. [the robot weighs around 100lbs]

What would perform better in your opinion:
-a standard pi[b+] utilizing ez-builder
-a mobile app using a phone with 4gb of ram
Are these two components comparing apples to apples?

Thank you,
the Pi version will give you more potential because plugins don't work on mobile. Also, with the Pi you can have more programs and different versions of programs. It's like having a little PC

Although, i do recommend Atomic Pi instead because it's $35 and runs windows. So it's just like having a laptop on your robot!
Atomic Pi is already sold out!!!

Thanks for the info!! Awesome find!!!:D

Hi DJ,

Thank you for the link and info on the Atomic Pi. 
I am going to wait until the Atomic Pi comes back in stock. 
I think this is the best solution for my requirements. 

In the meantime, can you recommend a suitable relay for a 12V source?
All of my robots will be getting this update. 

Would this relay be acceptable?

Thank you,
this is a good question for Jeremie. I’ll tell him to check the thread

12V automotive relays are definitely a robust option for switching 12V but personally I tend to stay away from relays. Relays are mechanical and do have a limited life. Automotive relays are definitely better as I have yet to have an automotive relay fail in any of my vehicles but I like to use MOSFETs instead. MOSFETs also don't have the electrical "ringing" effect of switch contacts and are audibly silent. There are a few caveats to using MOSFETs but there's tons of information online to sow you how to use them effectively. You can also purchase boards with the supporting circuitry already added. 

Here's an example from Amazon

Due note that MOSFETs do generate a lot of heat with high current loads so sometimes extra heat sinking is required.
