Following a crowdfunding campaign that raised an impressive $1 million earlier this year, Sphero’s STEM/STEAM kit RVR is now on sale. Announced back in February as part of the Colorado company’s first-ever Kickstarter campaign, RVR presents a bit of a change for Sphero in a number of key ways.

For starters, it’s a move away from the remote control ball design that has defined the majority of its projects since the Orbotix days. RVR is a four wheel system — and more than that, in keeping with Sphero’s relatively recent focus on education, aimed at helping kids learn languages like Python and JavaScript.
