Robots are being developed to perform jobs that humans either can't do or don't want to do, such as fighting fires, disarming bombs, and cleaning up nuclear reactors.
Smaller robots are now capable of inspecting and repairing pipes from the inside, offering a more cost-effective alternative to digging up buried pipes for maintenance.
Robots like the Carnegie Mellon modular robot can inspect and repair pipes using special resin to fix leaks, with some models capable of fitting into smaller pipes found in city water supplies.
While these robots may not be fast, they are effective in conducting pipe inspections and repairs, with technologies like spraying epoxy to form new pipes inside old ones being developed by companies like GE.
