The Pittsburgh Steelers are experimenting with remote controlled robotic tackling dummies in practice.

The dummies could aid in tackling development without the risk of players hitting each other.

"The applications we are quickly finding are endless," Mike Tomlin told the team's official website. "It never gets tired. It runs at an appropriate football speed. All of the position groups are getting an opportunity to use it. It's funny, you just put it on the field and watch the guys and they show you the applications. It's been fun watching that."

While still in the testing phase, the robot can mimic many football moves, cuts and has been clocked at a five second 40 yard dash time. The video displays the dummies being used for tackling, chase drills, as well as placeholders for defenders in passing practice.

"I imagine it's a great tool from a tackling tech standpoint," Tomlin added. "In today's NFL, with player safety the focus that it is, I think it's going to provide opportunities to improve in that area without the hand to hand or man to man combat associated with that teaching."
