A mobile virtual player, that is also a robotic dummy has just invaded the Pittsburgh Steelers off season workouts. On this very unusual training, the team will have to cope up if not beat this remote control operated tackling dummy.

Originally developed at Dartmouth College, this is the first time that this mobile virtual player will be joining and challenging the Steelers.

"The applications we are quickly finding are endless," said Mike Tomlin, Pittsburgh Steelers coach through 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," he added, according to NFL News.

ESPN reports that the robotic dummy was introduced to the Steeler's through Danny Rooney, a Dartmouth quarterback in the past and presently one of the Steeler's staffs. Dartmouth originally used the virtual player for workouts before Buddy Teevens, Dartmouth Football team coach banned its use for safety reasons. He was later assisted by the Thayer School of Engineering in keeping tackling a part of practice.

Pittsburgh Steelers players on the other hand are excited about this new companion and expressed their appreciation for this recent innovation.

Stephon Tuitt, Steeler's defensive player says the robotic tackling dummy is faster than what they have thought and what they have seen. He appreciates how the speed of the dummy is giving him an angle to the ball and able to view how a running receiver catches.

It is still unknown if aside from the Stelers, there are other teams using the robot on their training as the mobile virtual player is still on its testing phase. But one thing is for sure, there will be more of this tackling dummy in 2017, as per Toronto Sun.
