Claims17
A plurality of autonomous mobile robots, comprising:
- a first mobile robot including a first module for transmitting and receiving an Ultra-Wideband (UWB) signal;
- and
- a second mobile robot including a second module for transmitting and receiving the UWB signal,
- wherein the second mobile robot is configured to follow the first mobile robot using the UWB signal,
- wherein the second module included in the second mobile robot comprises two antennas,
- wherein the two antennas are disposed at outermost portions of a main body of the second mobile robot to have a maximum spaced distance between the two antennas on the main body,
- wherein the two antennas include a first antenna disposed on a front of the main body, and a second antenna disposed on a rear of the main body,
- wherein the main body of the second mobile robot attenuates intensities of the UWB signal, and
- wherein a control unit of the second mobile robot is configured to determine a relative position of the first mobile robot based on the intensities of the UWB signal received through the two antennas.
