SURF-BRISK–Based Image Infilling Method for Terrain Classification of a Legged Robot

Applied Sciences, 2019
In this study, we propose adaptive locomotion for an autonomous multilegged walking robot, an image infilling method for terrain classification based on a combination of speeded up robust features, and binary robust invariant scalable keypoints (SURF ...

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Feature-based terrain editing from complex sketches [PDF]

Computers & Graphics, 2014
We present a new method for first person sketch-based editing of terrain models. As in usual artistic pictures, the input sketchdepicts complex silhouettes with cusps and T-junctions, which typically correspond to non-planar curves in 3D. After analysingdepth constraints in the sketch based on perceptual cues, our method best matches the sketched ...
