Well, Japanese hobbyist Hinamitetu has finally managed to craft an acrobatic gymnast robot that can perform a mid-air somersault and grab back onto the horizontal bar without falling!  This is the 7th version of the robot, which appears to have a pressure sensor that activates the grippers on contact.  Who knows what’s next?  Perhaps he’ll work on the dismount.
