Beyond pick-place and quasi-static manipulation, robots are increasingly expected to perform more interactive and dynamic tasks in our daily life. However, it is still very challenging for the traditional manipulator because of its high stiffness and large mass/inertia. To address the above issues,
With the increasing demand for lightweight, large payload-to-weight ratio, and highly dynamic robotic arms for general-purpose applications, conventional designs inevitably face a significant trade-off among safety, payload capacity, and motion agility. This paper presents a 7 degree-of-freedom cabl
Most birds in nature rely on jumping for takeoff. Flapping-Wing Robots can flap and fly like birds but require an operator to take off, which are unable to generate sufficient lift to maintain flight at a low airspeed and must accelerate to take-off speed in a short time. It poses a challenge for th
Large flapping-wing aerial vehicles (FWAVs) face dual challenges in aerodynamic and structural design, with long-standing technical bottlenecks, particularly in roll maneuvers. In this study, by reverse-engineering the biomechanical mechanisms of raptor flight, we propose a bio-inspired wing-shoulde
Accurate state estimation of micro aerial vehicles (MAVs) in high-speed and dynamic environments poses a significant challenge for visual-inertial odometry (VIO) algorithms. Flapping-wing aerial vehicles (FWAVs), as an emerging flight platform, have attracted significant attention for stealth capabi
Cable-driven segmented manipulators (CDSMs) have high dexterity and large bending characteristics with less motors, which have great potential for long-range manipulation in structured environment. However, as joints’ number and segments’ length increase, the synchronous performance will largely dec
In this paper, we present a spherical wheel-legged mobile robot, aiming to meet the demands of adaptability to complex terrains and high maneuverability. It consists of a spherical main body and five-bar linkage parallel wheel-legged mechanisms. It can switch between legged and spherical modes by ex…
In this work, we achieved a self-takeoff of an eagle-scale flapping-wing robot for the first time. Inspired by the takeoff process of Ospreys, we propose a bio-inspired takeoff strategy, then discuss the dynamic model and the requirements for self-takeoff. Based on the requirements of flight strateg…
In recent years, there has been a growing demand for robotic manipulators to perform tasks in various unstructured environments and situations requiring precision and force control. However, traditional robotic arms have limitations in fully leveraging their advantages in such scenarios. To address…
Continuum manipulators have shown a wide range of applications due to their inherent compliance and dexterity. At present, the cross-sectional dimension of these manipulators is often kept constant, which facilitates the design, fabrication and modeling processes. The famous piecewise-constant-curva…
Cable-driven segmented manipulators (CDSMs) featured by superior dexterity, light and slender body are excellent candidates for operations in confined environments. However, the stiffness and load capacity of such manipulators have been a challenge due to their structural elasticity. In this paper,…
With a light and slender body, a cable-driven redundant spatial manipulator (CRSM) has flexible manipulability and high maneuverability in confined environment. However, compared with revolute rigid manipulators, such type of manipulators generally has low stiffness and weak load capacity. In this p…
For traditional manipulators, there is a large number of electrical cables between the motion controller and the joint servo controllers. It is very inconvenient for maintenance, update, and safe operation. In this paper, we develop a lightweight redundant manipulator with high stable wireless commu…
Capturing a moving object with large momentum by a dual-arm robot is especially challenging because of the requirement of dual-arm coordinated motion planning for tracking the moving object, and the operational force control for contact and momentum transfer. In this paper, we present a dual-arm coo…
With the rapid development of robotics, dual-arm robots have been more and more widely used. Compared with the traditional single manipulator, it is very challenging for a dual-arm robot in modelling, planning and control. In this paper, we propose two compliance control methods for dual arm coordin…
In this paper, we developed a small wheel-legged mobile robot system, which could walk on different road environments using wheels or legs. It is composed of mechanical, sensor and control subsystems. The mechanical subsystem includes a wheel-legged mobile platform, a rigid robotic arm and a flexibl…
This paper propose a practical and effective method for identifying the complete inertia parameters of a space robotic system. The key is the following steps: equivalent single-body identification, and equivalent two-body identification. For the former, all joints are locked into a normal configurat…
