Additionally, I presume you have a Robotics application which you're wanting to experiment with. With that said, maybe it could be beneficial to get one of the other variants initially. Then if you're like me, opt out of the wireless variants, and if you need wireless get a well supported dongle with an external antenna cable connection.
By well supported, I mean a dongle that uses a chipset that is well supported in Linux( Debian ), and is not too short. The length could potentially play a factor in interference with the HDMI, *if* you're using the HDMI output at all If not it is my understanding that you can simply disable HDMI to bypass that problem. I did want to say that I also own an rpi 3.0, and I know there is a lot more documentation all over the web concerning that platform. Some of the software, and utilities seem to be pretty good too. With that said, in the context of robotics, and general embedded Linux. I'd have to say that the beaglebone SBC's are light years ahead, in terms of flexibility, and connectivity. Where the beaglebone platform is also a platform that requires more knowledge from the user or engineer using it. Basically, aside from what you'll find googling, and what information people will share here. There is no hand holding on this platform. Which means you need to check everything you're working with. For instance, if you had any IO connected to this board through any of the GPIO, or other periphery pins while you powered the board up, or down. You could have damaged the processor. So all the pins need to be isolated in that case. Ethernet, USB, and the serial debug port are exceptions to this rule. But are not what I'd exactly consider "periphery" in the context of embedded systems.
