📌 MAROKO133 Breaking ai: Video: The ALLEX humanoid robot can shake hands without c

Meet ALLEX, a Korean-built humanoid robot designed to tackle one of robotics’ toughest challenges: safe, natural physical interaction.

At this year’s Consumer Electronics Show (CES 2026), WIRobotics’ ALLEX drew attention for its high-degree-of-freedom hands and arms, delivering human-like force control across the full body.

Named from “ALL-EXperience,” the robot can sense and respond to force, contact, and impact in real environments, complementing visual recognition and positional control.

Its precise force modulation and flexible motion suit both industrial applications and household tasks. WIRobotics positions ALLEX as a bridge between rigid automation and everyday human spaces.

Robots that feel

A humanoid robot capable of delivering a firm, natural handshake is offering a glimpse into a safer future for human–robot interaction.

Demonstrated in a recent video, ALLEX stood out for its ability to sense, apply, and respond to external force in real time. Unlike conventional robotic hands that feel rigid or passive, ALLEX’s grip actively adjusts, creating a controlled and human-like handshake, reports CNET.

The robot’s high-dexterity hands feature motors designed to be back-drivable, allowing them to be pushed or guided safely. Each finger can detect subtle forces, generate strong fingertip pressure, and maintain stable grips for lifting heavier objects. This balance of strength and flexibility enables precise manipulation without sacrificing safety.

Most autonomous robots remain behind safety barriers, but ALLEX points toward systems that can operate closer to people. While not yet intended for everyday deployment, WIRobotics aims to partner with other companies to integrate this force-aware technology into future humanoid and industrial robots, reports CNET.

“ALLEX goes beyond merely replicating human movement —it is the first robot that truly experiences and responds to the real world,” said Yong-Jae Kim, Co-CEO and CTO of WIRobotics, in a statement earlier.

Humanoid force control

Unveiled in August 2025, ALLEX is a humanoid robotic platform engineered to perform a wide range of tasks by responding to physical stimuli in ways that closely mirror human behavior.

The system features 15 degrees of freedom, enabling lifelike motion and complex, contact-rich interactions. Its force responsiveness is a key differentiator: ALLEX can detect and react to forces as small as 100 gram-force, even without tactile sensors, while delivering up to 40 newtons of fingertip force for secure and precise manipulation.

The robot’s arm system is designed for safe, fluid interaction, offering more than ten times lower friction and rotational inertia compared to conventional collaborative robots. This allows smoother motion, improved back-drivability, and greater safety when working alongside humans. Complementing this design is a gravity compensation mechanism extending from the waist to the upper body, enabling ALLEX to perform high-load tasks efficiently without excessive energy consumption or mechanical strain.

Despite its capabilities, ALLEX remains lightweight. The robotic hand weighs approximately 1.5 pounds (700 grams), while the shoulder-down assembly weighs about 11 pounds (5 kilograms). With one hand, ALLEX can lift more than 6.6 pounds (3 kilograms), achieving a strength-to-weight ratio that surpasses many larger robots weighing over 44 pounds (20 kilograms).

WIRobotics envisions ALLEX as a versatile solution across healthcare and eldercare, manufacturing, and household automation. The company plans to develop ALLEX as a modular platform, allowing users to deploy specific components based on application needs.

📌 MAROKO133 Eksklusif ai: World’s largest steam locomotive plans historic tour for

The US is preparing another historic coast-to-coast journey for Big Boy 4014, the world’s largest operating steam locomotive.

Union Pacific Railroad’s 600-ton engine, based in Cheyenne, frequently tours the western US but has not returned to the East Coast since it left the Schenectady, New York, factory in 1941.

The upcoming tour is planned to showcase the iconic locomotive across the country, though final arrangements on the eastern portion of the route are still being finalized, according to reports.

The trip could begin as early as the end of March, pending coordination with partners in the East.

Legendary engine back

Union Pacific’s Big Boy 4014 is one of only 25 Big Boy locomotives built during World War II to transport heavy equipment over the Wasatch Mountains to the West Coast, if needed, for the war effort.

Designed to overcome the region’s steep grades, the massive steam engine measures 133 feet long, 15 feet 4 inches tall, and 11 feet wide, weighing 600 tons when fully loaded with fuel and water—making it the largest operating steam locomotive in the world.

According to Cowboy State Daily (CSD), originally intended to be named “Wasatch,” the locomotive earned its iconic “Big Boy” moniker when a factory machinist scrawled it in chalk on one engine, and the name stuck. Its dimensions were carefully calculated to fit the tunnels, bridges, and curves of the era, leaving no room for larger designs.

Built at the American Locomotive Company in Schenectady, New York, starting in 1941, Big Boys were based in Green River, Wyoming, until they were retired in 1962. While some were lost over time, others were preserved in museums. No. 4014 was retired in December 1961 after logging more than 1 million miles. Union Pacific reacquired it in 2013, restored it in Cheyenne, and returned it to service in 2019 to mark the Transcontinental Railroad’s 150th anniversary.

Transcontinental rail adventure

Union Pacific is conducting a detailed inspection of the route for Big Boy 4014 in preparation for a potential coast-to-coast tour.

The effort involves measuring clearances along tracks to ensure the 600-ton steam locomotive can safely navigate bridges, tunnels, and tight spaces. Photos posted by the company show teams assessing track spacing and making adjustments where necessary to guarantee safe passage.

Safety precautions for the public, including maintaining distance from tracks and responsible photography or drone use, are being emphasized during the planning process, reports CSD.

According to officials, the nationwide tour requires extensive coordination across multiple teams within Union Pacific. Planning involves not only ensuring the locomotive can physically traverse the rail network but also integrating the trip with existing freight operations.

The company’s heritage operations teams handle mechanical maintenance, safety checks, and necessary modernizations, such as the addition of Positive Train Control, which allows Big Boy 4014 to operate independently on long stretches of track. Ongoing restoration work, including equipment upgrades at the steam shop, ensures the locomotive and other heritage engines remain in peak operating condition, reports CSD.

Big Boy 4014 is the only remaining operational Big Boy locomotive, while others are preserved in museums across the country. It has toured extensively across the western US, including a multi-state Heartland tour in 2024, but has never traveled further east than Chicago.

According to Union Pacific officials, a transcontinental tour would mark the first time the locomotive returns to the East Coast since it was built, offering a historic celebration tied to the nation’s 250th anniversary.

Last week, India signed a deal to build the world’s most powerful hydrogen locomotive, converting a diesel engine into 3,100-hp hydrogen power.
