The 2nd Robot Marathon has officially begun in Beijing. This year feels different. 1. Around 40% of teams are running fully autonomous, no remote control. 2. Top robots are already hitting ~10s per 100 meter, getting surprisingly close to human sprint limits. 3. You can also see much better safety design upfront. Way more structured than last year’s chaos. 4. Still, failures happen. Marathon distance pushes motors, structure, and control to the limit. What works in short demos breaks down over longer runs. Overall, a big step forward, but also a reminder that real-world robotics is still far from the polished demo videos you get fed from companies.

UBTECH’s robot is now showing off its boxing skills. Not long ago, the story was all about industrial deployment. Now it’s boxing. It increasingly feels like they are chasing whatever narrative is hot at the moment, rather than building around a clear strategic focus.

My favorite moment from the entire URKL Robot Fight! One brutal kick sent the robot's head hanging loose. and it somehow kept fighting like nothing happened! I completely lost it. Had to lower down the volume of my laugh 😂😂

A new industry is emerging alongside China’s humanoid robot boom: companies specializing in robotic clothing and flexible outer skins. KNITREAL’s RoboSkin uses seamless knitting, multi-directional stretch, and a soft matte finish to conform to moving joints and complex surfaces.

HopTo’s Hop-1 is a hybrid hopping-and-flying robot built for rough terrain. It looks weird at first, but the logic is actually pretty smart. Flying all the time burns a ton of energy just fighting gravity, so they let the robot spend most of its time bouncing on a passive spring instead. The rotors mainly steer, put back the energy lost on each hop, and only fully take over when the robot actually needs to fly. HopTo says hopping uses around 25% of the energy of continuous flight. So the whole idea is pretty simple: stay on the ground as much as possible, and only fly when you have to.
