When it was announced that the Los Angeles Rams would be using the Mobile Virtual Players, or robot tackling dummies, during their 2016 training camp, it was obviously an eye-catching move. Now, the much-anticipated debut of those tackling dummies is here, and it’s even more eye-catching.

While that video didn’t show exactly how fast those things can move, ESPN’s Jeremy Fowler previously pointed out that they can run a pretty impressive 40-yard dash.

“Each robot, costing about $8,000, weighs between 160 and 180 pounds, runs a 5-second 40-yard dash and cuts in the open field.” Fowler explained.

So while that tackle may have put the robot down fairly easily, they’re apparently much, much heavier than they look on film. Fowler explained that the Rams are joined by the Pittsburgh Steelers and Baltimore Ravens as the teams who are utilizing these new Mobile Virtual Players this offseason.
