Imagine this thing self-contained, with cameras and remote control, and armed with missiles, guns, or poison gas. And you have the soldier of the future. This is a prototype of a ground drone. Paid for by the same folks who actually did invent the internet - DARPA (Defense Advanced Research Projects Agency). Coming to a battlefield near you.
When these things are mass-produced and cheap, the dogface of yore will be replaced by actual imperialist running dogs. When boots-on-the-ground are no longer needed or wanted for warfare, the advantage of high-tech powers over low-tech ones will be complete. Once these things are ready for rollout they will be easy to miniaturize. A rat-sized one could go almost anywhere and be able to shoot a poison dart or a high-powered small caliber pistol.
Locked doors and windows? No problem. Every house has a 4" pipe connecting its toilet to the outside world. Robot goes up drain pipe from main sewer, waits until sensor shows terrorist is on the crapper, then literally pops a cap in his ass.
