RVR – which is pronounced "Rover" – is a big change for Sphero. First of all, it is not even a sphere! It's more a rounded brick, with a set of tank treads on each side. The front and rear lights and taillights are located just above the infrared ports that the RVR will use to communicate with other Sphero units. Bottom, a color sensor, provided by Specdrums, a startup of the music education sector that Sphero acquired last year. Being able to "read" the colors adds even more programming possibilities, but one can see the multitude of sensors when looking at the top of the device.
There is a clear plastic liner that reveals all the electronic parts underneath. There is also a light sensor, a magnetometer, an accelerometer and a gyroscope. The sensors are very effective in ensuring that the RVR goes where it is supposed to go; Blow the little guy and that goes of course correct. But the most notable is also what you can put on the robot: a special plastic cover with slots for all types of circuits and rotors and any other imaginable parts. Raspberry Pi and Arduino boards can be attached, as well as all types of servos, external sensors or speakers if you wish.

Not happy parts there? Advanced users who have started manufacturing their own circuit boards can also be hosted – the RVR has a standard 4-pin UART port, so it's easy to create your own room configurations without worrying about exclusive connectors. If the current mounting plate does not do this for you, Sphero will publish designs so that you can print 3D replacements tailored to your specific needs.
The RVR can be programmed using the standard Sphero EDU application, although you can also hack your own interface. Sphero does not try to lock it. It will not even sell parts, but will combine the RVR with Sparkfun cards. Sphero wants to encourage piracy and creativity as much as possible – it's not just tables or lights that have to fit into the top mounting plate; it should be able to support mechanized parts and maybe even blades if you plan to build some kind of tiny murder machine. (It's not that we recommend you do it.) At least one child went so far as to build some kind of "weed wacker" for the dandelions in their garden.

What if, for some reason, you do not want to change your RVR? Well, that's good too, because it's still a perfectly usable remote-controlled vehicle that can sneak around the ground, handle angles well, and climb short objects. There is even a special top plate for the driving style, with a turtle roof. Thus, if she turns around, she will have more chance to recover.
If you can not wait to have your own Sphero tinkering, RVR will first launch on Kickstarter, which the company prefers so that it can receive feedback from what it considers to be technology-savvy users. These first contributors will pay $ 199 for one unit (compared to a final MSRP of $ 249) and will get their RVR robots in September.
