1. A tool for intervention on a wall of a fluid pipe, the tool comprising:
a duct segment through which the fluid is intended to flow when the tool is in the pipe, and
at least first and second modules configured to create seals between the wall of the pipe and the duct segment and to isolate the fluid circulating in an outer part of a section of the pipe between the first and second modules;
wherein the tool includes motorized rollers configured to move the tool in the pipe and a module configured to determine a location of the tool in the pipe;
wherein the module configured to determine the location comprises a sub-module configured to receive at least one remote signal;
wherein the sub-module configured to receive at least one remote signal includes a magnetic sensor;
wherein the tool further comprises a module configured to determine a speed of the tool based on a detection of at least two magnetic signals by the magnetic sensor.
