Welcome to My Academic Website!
Chunxu Tian is an Associate Researcher (Equivalent to Associate Professor in Research Track) at the Academy for Engineering & Technology at Fudan University. His research interests include advanced robotics, with a focus on Robotic Mechanisms, Parallel Robots, Humanoid Robots/Quadruped Robots, Dexterous Hands, Bionic UAV and Origami Robots. He has led multiple national projects and made significant contributions to the field.
Tian's innovative research addresses critical challenges in robotics, particularly in overcoming the limitations of traditional parallel robots. His work resolves key conflicts and incompatibilities between various performance aspects, pushing the boundaries from conventional “weak coupling” designs to “strong coupling,” and from “fixed configuration” systems to more adaptive “variable configuration” models. These contributions are driving the development of more versatile and capable parallel robotic systems.
Serial and parallel robots, both pivotal in automation, have distinct characteristics.
Serial robots feature an open kinematic chain with multiple joints and links, offering a large workspace and suitability for tasks requiring extensive movement. However, their load capacity is relatively low, and accuracy can be compromised by error accumulation.
Parallel robots, with closed kinematic chains, provide high - precision motion in a limited workspace, making them ideal for precision - demanding tasks. They can bear heavy loads relative to their weight and minimize error accumulation and deformation with their rigid structure.
In terms of control, serial robots use relatively simple joint - space control, while parallel robots need advanced algorithms to coordinate multiple actuators. The choice between the two depends on whether the task needs a large workspace or high - precision positioning.
