Under-actuated Robotic Gripper with Multiple Grasping Modes Inspired by Human Finger
Jihao Li, Tingbo Liao, Hassen Nigatu +3
Under-actuated robot grippers as a pervasive tool of robots have become a considerable research focus. Despite their simplicity of mechanical design and control strategy, they suff…
Theoretical Modeling and Bio-inspired Trajectory Optimization of A Multiple-locomotion Origami Robot
Keqi Zhu, Haotian Guo, Wei Yu +3
Recent research on mobile robots has focused on increasing their adaptability to unpredictable and unstructured environments using soft materials and structures. However, the deter…
Unveiling the Complete Variant of Spherical Robots
Hassen Nigatu, Li Jihao, Gaokun Shi +2
This study presents a systematic enumeration of spherical () type parallel robots' variants using an analytical velocity-level approach. These robots are known for their abi…
Workspace optimization of 1T2R parallel manipulators with a dimensionally homogeneous constraint-embedded Jacobian
Hassen Nigatu, Doik Kim
This paper presents the workspace optimization of one-translational two-rotational (1T2R) parallel manipulators using a dimensionally homogeneous constraint-embedded Jacobian. The…
Dimensionally Homogeneous Jacobian using Extended Selection Matrix for Performance Evaluation and Optimization of Parallel Manipulators
Hassen Nigatu, Doik Kim
This paper proposes a new methodology for deriving a point-based dimensionally homogeneous Jacobian, intended for performance evaluation and optimization of parallel manipulators w…
