Seems as though robots would do a much better job. I'm imagining a giant spider that walks into a minefield with its armored body fairly high above the ground.

Seems as though robots would do a much better job. I'm imagining a giant spider that walks into a minefield with its armored body fairly high above the ground. The body very methodically scans, probes, digs, ...whatever works. Its probes sometimes get blown off and are replaced from a quiver. A leg is occasionally blown off, but a spider can keep working without a leg or two. At the end of its shift, it walks out and has its legs fixed. A big hook on its back can be snagged to helicopter it out in case it is immobilized by an uncaught exception.
