This paper presents a new kind of climbing robots called EJBot, which has not been restricted to climb certain surface materials or terrains. EJBot is inspired by propeller-based aviation systems, however, its adhesion principle opposite flight concept. Thanks the hybrid actuation system embedded in this robot gives good and stable adhesion. consists propeller thrust forces wheel torques actuated simultaneously generate proper force. It similar car ramp, it needs both weight wheels' torques....
Path-planning algorithms for cleaning robots typically focus on how the can cover an entire space while minimizing overlapping or uncleaned areas. However, when considering actual environments, distribution of dust and dirt is not uniform has some specific features according to shape environment human behaviors. Therefore, if a robot plans its path taking this into consideration, it clean area more efficiently. In paper, we present novel path-planning algorithm that prioritizes regions with...
