ABSTRACT:
A mobile communication device can perform direct communication with another mobile communication device without providing a new communication circuit. The mobile device moves by driving wheels rotated by a motor. A pressure sensor is provided on an outer surface of the body of the communication device to detect contact pressure with another mobile communication device. A control circuit maintains a constant level of driving force of the motor when the communication device is in contact with another mobile communication device and receives data by determining changes in the detected contact pressure which correspond to the predetermined transmission data. Alternately, data exchanges maybe performed using the relative distance between the communication devices.
