Robot trips over and explodes in Beijing half-marathon rehearsal

A marathon-running robot has smashed into pieces in dramatic fashion after tripping during the rehearsal for a half-marathon* event in China.

The robot runner face-planted over the start line during a training session for Beijing‘s humanoid* robot half-marathon.

Footage shows the lifelike machine poised and ready to begin – before it suddenly stumbles within moments of setting off.

In a split-second, the humanoid catastrophically crashes to the ground, with chunks of its frame flying through the air.

The only thing left on the track were the robot’s legs twitching helplessly.

In a hilarious twist, an emergency crew made up of five people sprinted over with a robot-sized stretcher to scoop up the shattered remains.

The bot’s broken body was then carried away – leaving scraps of metal pieces scattered across the course.

The human-like runners, typically standing at 178cm and weighing 55kg, have been described by fans of the event as “highly human-like”.

The slapstick* scenes unfolded during a full rehearsal for the world-first humanoid robot half-marathon in Beijing, China, just days ahead of the official race on April 19.

The test event, held across April 11 and 12 in the city’s E-Town Economic and Technological Development Area, was designed to simulate every aspect of the race.

Participants tried out route navigation, timing, equipment co-ordination and emergency response.

More than 70 teams took part in the rehearsal, including four international groups, with both autonomous* and remote-controlled machines competing.

Participation in the official race has surged this year, with more than 100 teams entering.

The final race saw more than 300 robotic entrants compete in the 21km run – a huge jump from last year’s race, when just 21 robots took part and only six managed to finish, with the rest tripping, overheating or failing mid-run.

According to tech publication The Next Web, humanoid robot Lightning went on to win the main event on April 19 with a time of 50 minutes and 26 seconds, beating the human world record by almost seven minutes.

The staggering result was a huge contrast from last year’s winner, Tiangong Ultra – a towering, lightweight model painted midnight black – which crossed the line in two hours and 40 minutes.

HOW THE RACE WORKS
Competitors are split into two main categories: autonomous navigation and remote control – with autonomous systems making up nearly 40 per cent of the field in this year’s competition.

About 12,000 human runners also competed in the half-marathon, running the same course but in separate lanes to their humanoid counterparts, according to The Next Web.

The rehearsal followed the full 21.0975-kilometre half-marathon route under official race conditions, testing performance across urban roads and ecological* park terrain.

Maintaining balance over long distances has remained one of the biggest challenges for robot runners, since it requires split-second posture changes to prevent falls.

Engineers have also been battling issues around battery life and energy efficiency*, since long-distance running puts heavy strain on power systems.

Teams have been working to refine gait* control to keep their creations stable and fast over long distances.

New rules have also been introduced, reducing how much humans can intervene while standardising* race procedures.

Clearer scoring systems, improved methods of resupply and enhanced safety frameworks were all rolled out ahead of the main event.

Officials claimed the race marked a major leap in pushing humanoid robotics beyond lab settings and into real-world environments.

• slapstick: a style of physical comedy involving exaggerated movements such as falling, chasing and getting hit but doesn’t involve any pain or injury
• autonomous: a machine that can control itself
• ecological: wildlife and the way different organisms relate to one another
• energy efficiency: the ability for an appliance to minimise the amount of power it uses
• gait: someone’s manner of walking or running
