That little robot in the video can be used for disarming bombs and repairing vehicles in multiplayer games. It's part of the engineer class.
They also clarified how spotting will work in the game, a change they've adjusted since Alpha.
"So, a soldier in direct Line of Sight that is spotted will have a 3d red marker. If he moves behind cover or concealment, including vegetation, the 3d red marker will disappear. He will always be on the minimap. Vehicles are always fully 3D spotted, and LOS does not apply since they are larger more important targets with less threats (and it plain did not work to have jets flying around who couldn't see the tank you spotted for him to take out).
This lets you essentially "nudge" your buddy to tell him about a target, or point out a sniper on a hill you see but cannot engage (with your shotgun for example). But it prevents players from using 3D spotting as a wall hack.
Additionally, the primary motivator for the change is that 3D spots that you cannot see are not threats. We noticed that players would focus on 3D spots over everything else, meaning they would ignore people in line of sight. It's far less confusing when the 3D spot on a soldier can only be seen if you can see the soldier."
