Abstract: This disclosure presents a robotic device for multi-terrain inspection, composed by a robot body, a quick reconfigurable locomotion module and a mapping unit capable to model the inspected environment through a 3D colored point cloud. The robot has different locomotion mechanisms that can be quickly replaced, thereby changing the robot mobility characteristics. The device is controlled through teleoperation or autonomously. When in teleoperated mode, an operating assist module provides relevant locomotion information to the operator including a map that shows areas where the robot may not transpose or tip-over. This module also suggests to the operator other locomotion configurations to overcome obstacles presented in the map. When in autonomous mode, the navigation module provides a strategy to explore unknown environments and trace optimal locomotion path considering the traveled distance, tipping-over risk and energy consumption.
