Matrix multiplication seems complex until you observe it step by step. Watch how each of the nine entries is formed: one row from matrix A, one column from matrix B, three products, and one sum.
Caltech researchers taught a Unitree G1 humanoid robot to run using a single human motion demonstration.
They used mathematical optimization to turn that one demonstration into a library of different running movements for the robot to learn from.
After training, the G1 reached speeds of up to 3.3 m/s and could run outdoors while avoiding obstacles.
Generating a city in Blender takes about 30 seconds now.
iCity builds roads, towers, parks and traffic procedurally — aimed at driving sims, city flythroughs and archviz context.
🇨🇳 China just unveiled a robotic fish modeled on an arapaima that is disturbingly hard to tell from the real thing.
The obvious question is whether this becomes useful marine robotics, surveillance tech, or the beginning of an aquarium where nothing is actually alive.
Even fish need firmware these days.

A humanoid every 10 minutes. UBTECH’s new Liuzhou factory is up and running, with a line designed for that pace and planned annual capacity above 10,000 robots.
Last December, this site celebrated its 1,000th Walker S2. Less than nine months later, it’s gearing up for five-figure annual production.
UBTECH reported 921 full-size humanoids sold in the first half of 2026. On September 10, it announced over RMB 50M (about $7.5M) in recent overseas orders from Europe, Japan and South Korea, including Walker C1 and U1 robots.
