Energy Efficiency of a Wheeled Bio-Inspired Hexapod Walking Robot in Sloping Terrain

open access: yesRobotics, 2023
Multi-legged robots, such as hexapods, have great potential to navigate challenging terrain. However, their design and control are usually much more complex and energy-demanding compared to wheeled robots.

Community-managed Traditional Means of Irrigation in the Semi-arid Aravali Landscape

open access: yesOpen Rivers, 2021
Earthen channels winding like serpents across a hilly landscape are not a common sight everywhere. They appear quite misplaced in a terrain that is highly undulating and rugged, covered with dry deciduous forests and dotted with rocky outcrops.

Frame Effective Tilt Correction for HEM Data Acquired over Rugged Terrain

open access: yes, 2015
International audienceIn a traditional HEM inversion scheme, the voltage data are usually normalized by the effective area of the system. This effective area depends on the tilt of the frame; the pitch and the roll of the frame are monitored during the ...
