The camera captures the moment when the lithium-ion battery of a disaster relief robot explodes and burns.

The lithium-ion battery installed in the disaster relief robot 'RoboSimian', which is being developed by NASA's Jet Propulsion Laboratory (JPL) and can move in a well-balanced manner even in the presence of obstacles using four legs. Exploded, and an accident occurred in which peripheral parts were involved and burned. Since it was an accident that occurred during an experiment at the laboratory, the whole story from before the explosion to the extinguishing of the fire is recorded in the video.

RoboSimian Lithium-Ion Battery Fire

Here is an animated GIF that cuts out the burning part.

On the NASA site, you can see a movie of what happened before the fire.

This is Robo Simian.

The accident happened after 11:00 on June 14, 2016. We replaced one of the lithium-ion batteries installed by four JPL researchers with a new one and started charging.

Robo Simian continues to charge at the laboratory ...

However, at around 11:47:59, black smoke suddenly spewed out in all directions ...

Only 2 seconds later, at 11:48:02, the fire went up.

The flame that extended in the lateral direction has disappeared, but the main body is on fire.

Within 30 seconds of the smoke coming out, a staff member with a fire extinguisher will rush.

However, I couldn't extinguish the fire even if I used the whole one ...

The hands of fire are bigger. The tip of the flame is slightly purplish red.

I managed to extinguish the fire using another fire extinguisher.

It seems that he went to call for firefighting during this time, but white smoke is still rising from the main body with great momentum.

When I think that the image has become vaguely difficult to see ...

Approximately 4 minutes after the temporary fire was extinguished, the flames reignited.

This time, two fire teams dressed in equipment came and extinguished the fire again.

Open the door leading to the outside.

As I was working, Robo Simian, who seemed to have extinguished the fire, saw a flame ...

Eventually, Robo Simian was taken out.

The lithium-ion battery used in this RoboSimian is a 96-cell battery. Professor Jay Whitacr of Carnegie Mellon University, who has experience at JPL, points out the danger, 'Lithium-ion batteries have a lot of power, so if they are released quickly, it can be catastrophic.' ..

Samsung's Galaxy Note 7 has often been on fire and talked about, but given that it was a minor accident at RoboSimian, I realize the danger.
