YouTuber Die Struktur created the first rotating cat automaton that paints to musical accompaniment. Now, instead of "my kid could paint that," idiots can say "my maneki-neko on a turntable could paint that." Read the rest
Disney Research Zurich and ETH Zurich (Swiss Federal Institute of Technology) developed VertiGo, a mobile robot that can roll up walls. It uses two tiltable propellers that keep it rolling and also provide the thrust that keeps it against the wall when moving vertically.
“About why Disney is interested in this area, I am not able to say specifics as you can understand," Disney Research scientist Paul Beardsley told IEEE Spectrum. "But just speaking in general, one can imagine that robots with lighting effects could be useful for entertainment effects or for wall games. This also relates to the question of why the ground-wall transition is useful. If you have to manually place a robot on a wall at the start of a deployment, and manually remove it at the end, then that's taking manpower and it's not flexible. If the robot can make those transitions automatically, then you are a step in the direction of autonomous deployment, and that makes the technology more powerful. We are motivated by making a practical device, so it is real-world feedback and challenges that drive our work.”
MIT researchers developed this "Soft Cube Capable of Controllable Continuous Jumping." From IEEE Spectrum:
Inside of the robot there are two motorized rotors, each connected to one end of four flattened loops of spring steel. Activating the rotors causes the spring steel loops that I’m just going to go ahead and call tongues to get pulled through rectangular openings (mouths) into a round cavity inside the body of the robot, compressing them. As the rotors continue to turn, eventually the compressed tongues get pulled all the way around back to the mouths, at which point they spring out, releasing that elastic energy all at once and causing the robot to jump.
"With some light-weight payloads, such as miniature cameras, the robot can be used for exploration tasks," write the researchers. "Moreover, a wireless sensor network can be automatically deployed and reconfigured for outdoor surveillance by using a group of our jumping robots."
Next, they hope to increase the robots' power so the cubes can jump higher and cover more ground.

Researchers from Japan's Chiba Institute of Technology demonstrated this spherical robot that rolls around until its four legs pop out for scurrying. Like a quadruped robot disguised as a Spheero! From the scientific paper (PDF):
We have proposed and developed a new quadruped walking robot with a spherical shell, called "QRoSS". QRoSS is a transformable robot that can store its legs in the spherical shell. The shell not only absorbs external forces from all directions, but also improves mobile performance because of its round shape. In rescue operations at a disaster site, carrying robots into a site is dangerous for operators because doing so may result in a second accident. If QRoSS is used, instead of carrying robots in, they are thrown in, making the operation safe and easy. We developed QRoSS-I and conducted basic experiments to verify performance which includes landing, rising and walking through a series of movements.(via IEEE Spectrum)
Jerboas use their long tails to transfer energy to their legs, allowing them to hop many times their body length. It turns out the hair on the bottoms of their their feet also serves a number of purposes, including insulation, traction, and stealth on the sand.
