Just asking to those with more knowledge than me. How is this any different to a RaspberryPi or a Beagle Bone Black?

As someone who makes a lot of robots, I will support this on principle. I really like that the board can accept a high current power source and has a cutoff switch.<p>I am always a little nervous about building a robot around a board when I am uncertain about how it will be supported. If you are really building robots that are going to be used out doors or in rugged environments you want to be able to replace every part. Controller boards aren&#x27;t really the expensive part of robots.<p>For Decapitron, an autonomous combat robot (<a href="http://forums.parallax.com/showthread.php/140197-Decapitron!" rel="nofollow">http:&#x2F;&#x2F;forums.parallax.com&#x2F;showthread.php&#x2F;140197-Decapitron!</a>), I have had to replace the controller board twice. That may sound like a lot but shorts and power surges aren&#x27;t that strange in combat. But now that board isn&#x27;t made anymore. So it is a big problem if the board gets damaged in combat. That&#x27;s the advantage of using something really standard, like Arduino or Raspberry Pi. I can get one of those next year.<p>Still, I will try this.

As a hobbyist AI programmer with few hardware skills my dream is a for an out-of-the box robot with basic movement, sensors and maybe an arm that I can start programming for in a higher-level language. Rex looks like a huge step in that direction. If they could throw in a chassis for mounting standard motors and sensors, even my multi-thumbed self might be able to make it do something cool.

I wonder how much power it drains. The RaspPi uses &quot;only&quot; 3 Watt, but that is a way too much for many interesting applications. There are some hacks to reduce to the power usage (by replacing the voltage regulators for example) but i wonder how much this board will use.

I always wonder with these boards why wifi isn&#x27;t just built-in. It seems like a delightfully simpler interface than any wire, and means the base system can integrate with anything else over the network. Sure you can always add wifi, but the point of these boards is that they bundle all the basic stuff, and often include things like development environments that can&#x27;t make use of wifi if they don&#x27;t know if it is available. Power is a concern, but you can still turn it off.

Couple of things I wonder:<p>- SdCard + full-blown OS = SdCard dies after a while? Or more serious problems like the rPi simply yielding it empty? Could another type of storage be used to boot and run from?<p>- more information on the OS? What&#x27;s it based on? Open source so we can fiddle with it?<p>- what processor is that exactly? Likely the manufacturer provides an OS + libs for it as well (like Ti does for their OMAP), probably the board can be booted with that as well?<p>- will the schematics be open-sourced?<p>- debugging capabilities of running programs?<p>btw quite some comments starting with &quot;I wonder&quot; here. Authors should provide more information probably..

Am I the only one to see this and think &quot;They&#x27;re going back to PCMCIA?&quot; (see <a href="http://en.wikipedia.org/wiki/REX_6000" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;REX_6000</a> for a &quot;palm-sized single-board computer&quot; complete with 240x120 monochrome touchscreen).
