A mobility system comprising: a mobility including an operation unit configured to detect an operation instruction input by a user, a travel drive unit configured to drive and cause the mobility to travel at a travel speed and in a travel direction according to the operation instruction detected by the operation unit, a biosignal detection unit including an electrode configured to detect a biosignal of the user from the user's finger when the user's finger comes into contact with the operation unit, a voluntary control unit configured to generate a command signal for causing the travel drive unit to generate power according to the user's intention based on the biosignal acquired by the biosignal detection unit, an environment sensing unit comprising a laser range sensor, an RGB-D sensor and a 3D distance image sensor configured to sense a travel environment during travel, an information acquisition unit comprising an imaging camera and a directional microphone configured to acquire at least one or more types of environmental information from an external environment using the imaging camera and/or the directional microphone, a travel adjustment unit configured to adjust a current travel state of the mobility to an optimal travel state for ensuring safety while reflecting the user's intention based on the current operation instruction detected by the operation unit, the command signal generated by the voluntary control unit, the travel environment sensed by the environment sensing unit based on Simultaneous Localization and Mapping Technology, SLAM, based on signals from the laser range sensor, the RGB-D sensor and the 3D distance image sensor, and the respective types of environmental information acquired by the acquisition unit, and a travel control unit configured to control the drive and travel of the mobility by the travel drive unit so as to attain the travel state adjusted by the travel adjustment unit. a mobility including an operation unit
