Found an image of the bot'.
looky looky image here!
Judging from the dimensions of the vehicle/bot/whatever you want to call it, you could probably disguise it as a bush or a rock and people'd be none
the wiser.
An expendable survellience tool that can penetrate enemy lines without them even knowing what it is that's penetrated them...
All you'd need to do is turn off the electricity on the border fences and this thing could put a hole in it itself, next thing you know the enemy
forces are searching for a saboteur that doesn't even exist...
You could probaby get it to lay mines over important logistical supply lines if you wanted, and it'd be off again disguised as a rock while the enemy
sits there wondering how the hell their opponents are getting behind their front lines.
Not only a good watchman, but an incredibly powerful tool of subterfuge.
