Chinese engineers are training an AI-powered robot to skate.
In a significant leap for embodied artificial intelligence, Chinese engineers at institutions like the University of Science and Technology of China and firms such as Unitree Robotics are training a new generation of robots to master the complex dynamics of skating. Using a specialized 25-degree-of-freedom humanoid aptly named SKATER, researchers have implemented deep reinforcement learning to teach the machine “swizzle” motions—a technique where the robot propels itself by repeatedly widening and narrowing its stance without lifting its feet. Unlike traditional bipedal walking, which is energy-intensive and taxing on mechanical joints, this AI-driven skating approach significantly reduces the Cost of Transport (CoT) and increases operational endurance, making it a highly efficient mode for urban traversal. By utilizing “sim-to-real” training pipelines, these robots are learning to autonomously adapt to various surfaces and inclines, shifting the paradigm from rigid, pre-programmed movements to fluid, human-like athletic grace that could eventually see humanoid agents navigating city streets with unprecedented speed and efficiency.
George Ntavoutian conquers an epic full-pipe.
Madrid’s scene is about to level up with the highly anticipated arrival of El Hangar Indoor Skatepark, a massive new destination designed to keep wheels turning regardless of the weather. This state-of-the-art facility promises a premium indoor environment featuring high-quality ramps, street elements, and flow zones tailored for skaters of all skill levels. By bridging the gap between urban street culture and a professional training ground, El Hangar is set to become a vibrant community hub for skateboarders, rollers, and BMX riders alike. Keep an eye out for its grand opening, as it aims to redefine the local action sports landscape with its sleek design and year-round accessibility.

Addis Skatepark in Ethiopia is expected to be demolished to make way for a football field.
The proposed demolition of Addis Skatepark, Ethiopia’s first concrete skate sanctuary, marks a bittersweet turning point for the capital’s urban landscape as the city prioritizes large-scale athletic infrastructure. Since its construction in 2016 through a massive grassroots effort by Ethiopia Skate and Make Life Skate Life, the park has served as a vital community hub for youth in the Sar Bet area, fostering a unique culture of creativity and inclusion. However, with Addis Ababa currently undergoing an aggressive “Corridor Project” modernization and preparing a bid for AFCON 2029, the land is slated to be repurposed for a football field—a move that underscores the ongoing tension between niche community spaces and the government’s focus on mainstream sports like football. While the loss of the original concrete park is a significant blow to the local skate scene, it highlights the urgent need for the city to integrate diverse recreational spaces into its rapidly evolving “New Addis” master plan.
Xavier Gilbee wins his first national title.
In a high-octane display of speed and technical precision, Xavier Gilbee officially cemented his status as a rising force in the sport by capturing his first career national title in BMX. Navigating the treacherous rhythm sections and steep berms with seasoned composure, Gilbee delivered a clinical performance that left the field trailing in his wake. This milestone victory is more than just a trophy for the mantel; it represents the culmination of years of relentless training and marks a definitive “arrival” on the national stage. With this gold medal secured, Gilbee has transitioned from a promising contender to a legitimate champion, setting a blistering pace for the rest of his season.
