Engineers with the US Army recently
completed tests on a 20-ton unmanned Stryker vehicle, intended to be used as part of a convoy. In the tests, the robot
vehicle was able to follow a manned vehicle at speeds averaging 22 miles per hour, topping out at 40 on straightaways.
The robotank was also able to detect obstacles laid down by the lead vehicle and maneuver around them. One of the big
advantages of the vehicle appears to be the ability to operate without GPS, instead relying on terrain data sent from
the lead vehicle and data gathered from on-board sensors; soldiers will remain in the vehicles for now, but in the
future, these mech-warriors could be used for tasks like resupplying forces in dangerous environments.
