Mobile robots are becoming part of our every day living at home, work or
entertainment. Due to their limited power capabilities, the development of new
energy consumption models can lead to energy conservation and energy efficient
designs. In this paper, we carry out a number of experiments and we focus on
the motors power consumption of a specific robot called Wifibot. Based on the
experimentation results, we build models for different speed and acceleration
levels. We compare the motors power consumption to other robot running modes.
We, also, create a simple robot network scenario and we investigate whether
forwarding data through a closer node could lead to longer operation times. We
assess the effect energy capacity, traveling distance and data rate on the
operation time
