The second annual Robot Art contest Is in its final lap:
The Robot Art 2017 competition will be running between now and May 15th when more than $100,000 in awards will be given to the top painting robots. Winners will be determined based on a combination of public voting, professional judges consisting of working artists, critics, and technologists, and by how well the team met the spirit of the competition – that is to create something beautiful using a physical brush and robotics.
You can help by voting on the artwork now!
Dave wrote in about the EggBot:
My daughter wanted to tell you that she loves your creation. The other day she told me that she is more sciencey than girly, and I told her that she could be both. I have attached a picture of her with her first multi color print, Wonder Woman.
Thank you for sharing, and the egg turned out great!

Today we are releasing our newest set of “Download and Print” cards for Valentine’s day. This is our fifth year, and fifth set of cards: The 2013 set had six equation-heavy cards, the 2014 set was a set of six symbol-heavy cards, and the 2015 set included love, hearts, and arrows. The 2016 set featured Pluto’s cold heart, and the perfect card for your robotic expression of love.
This year’s set features relativity, atomic orbitals, exponential growth, an LC resonator, and an epsilon delta declaration of love.
“You put me in an excited state.”
Roses are red. Which does suggest that they’re moving away from us, quickly.
While this sounds much like an “epsilon delta proof,” it lacks the logical rigor that we would normally associate with one. It’s more of a postulate, really.
“You make my heart feel like sin(1/x)….” If your heart isn’t jumping yet, you’ve probably never tried to graph that.
The original title for this one was “my love for you grows exponentially.” But hey, your valentine is smart (or you wouldn’t be sending these kinds of valentines): Let them do the math.
You can download the full set here, which includes all 30 designs from all five years (a 1.5 MB PDF document).
As usual, print them out on (or otherwise affix to) card stock, personalize, and [some steps omitted] enjoy the resulting lifelong romance.
