At China's robot Olympics, the finish line comes with a padded wall and a stretcher

Humanoid robots parade down a track at the start of the World Humanoid Robot Games in Beijing on Saturday.

Robots sprinted, played soccer, boxed — and occasionally crashed into walls.

The spectacle comes as China pours money into its booming humanoid robot industry.

The robot uprising may have to wait.

For now, the machines are still running headfirst into walls, both literal and metaphorical.

That reality was on grand display at the second iteration of the World Humanoid Robot Games, a five-day competition held in China where robots compete in Olympic-style events, which kicked off on Saturday.

Notably, in a test run, a humanoid robot named "Lightning" ran the 100-meter sprint faster than Usain Bolt did in his world-record dash in 2009, according to Chinese state media reports.

Saturday's events featured "preliminary" versions of the 100-meter and 400-meter sprints, a 7-on-7 soccer match, and brief demonstrations of other events, according to Beijing's government, which hosts the competition.

The proceedings are being livestreamed by Sports Insider on YouTube.

Though the robots can reach high speeds on the track, slowing down is another issue entirely.

A blue padded wall was positioned at the end of the track on Saturday, which several robots crashed into violently.

Some lost limbs in the process.

After each race, a four-man stretcher team emerged to carry them off the track.
