And so a little robot can go around the room and pick up Coke cans - - that 's a usual task for robots - - or it can go into a nuclear plant and do clean-up . During our work with remote control interfaces for robots we have explored several techniques . Military robots can be used for disposing of explosives , combat engineering tasks like clearing mines or placing explosives , reconnaissance , detecting nuclear and biological agents , and hazardous materials cleanup , among others tasks . HANSON : I 'm interested in making these robots easily custom-designed and mass producible - - in other words , easily designed using low-cost hardware , so that very inexpensive facial expressions can go with inexpensive walking robot bodies , as well as easily customized software . You could use both a robots.txt file and <meta name="robots"> tags on a website to give both broad and very detailed instructions to indexing robots . During this decade , military robots will probably save lives not by fighting , but by performing some of the more mundane but still hazardous support activities .
