“I'll risk forty dollars that he can outjump any frog in Calaveras county” Jim Smiley and His Jumping Frog – 1865  Mark Twain 

The Mark Twain House & Museum’s The RoboFrog Race of Hartford County

Date to be announced

After the success of the Robotic Jumping Frog Competition in 2019, we are going to do it again.  This year the RoboFrogs will be racing, hopping, and jumping their way through the lily pads.  We invite inventors and makers of all ages to design, submit, test and finally compete in the RoboFrog Race of Hartford County. 

We will be offering RoboFrog Workshops over the course of the lead up to the event.  Please watch your emails for announcements.
