Main Research Projects

1.Exoskeleton robot

The quantity of people suffering from walking disturbances shows a trend of rising in recent years. Spinal cord injuries may lead to hemiplegic or paraplegia. And a large number of people have difficulty walking due to old age. However, rehabilitation equipments in hospitals still have several deficiencies. First of all, a lot of rehabilitation equipments need collaboration of multiple caregivers, which is laborious and time consuming; Second, in the process of using, a lot of equipments lack of tracking patients' physical and biological conditions; Moreover, some complex equipments require quite a long time to prepare, leading to low efficiency, and the maintenance cost is very high; Finally, most of the existing rehabilitation solutions are subject to environmental constraints. The lower limb Exoskeleton robot has many advantages, such as, the caregiver can take care of more than one patients at the same time. The robot can record the physiological state of patients simultaneously. And it is easy to wear and take off, and easy to adjust to local conditions.

4.Research on Key Technology and Applications of Robot Intelligent Control Based on Learning Human Actions

Although the fundamental research and commercialization on robotics have been greatly developed for several years, the intelligent decision making abilities of robotics on planning and control are still falling far behind human beings, no matter on manufacturing, helping the aged, medical care and relief, search and rescue, etc., which is a problem restricting the development of robotics for a long period of time. To tackle this problem, we focus on in-depth theoretical studies on three aspects based on the learning and imitation of human actions, including high-level task planning, complex trajectory tracking and position/force control.

Specifically, the main research contents include three aspects: (1) Research on high-level planning methods of how to combine the operating primitives through learning from human demonstrations; (2) research on the intelligent tracking methods of anthropomorphic complicated paths, and ensure the convergence on a specific working point; (3) research on the applicability of common robotic compliance control methods (such as impedance control, position/force control etc.), and develop new intelligent compliance control methods. Furthermore, we build a variety of experimental platforms, such as industrial robots, rehabilitation robots etc., to verify the proposed theory and methods of robotic anthropomorphic behavior control studies.

Application Scenarios

7.Magnetically actuated helical microswimmers: visual servo control

Helical microswimmers capable of propulsion at low Reynolds numbers have been proposed for numerous applications, ranging from in vitro tasks on lab-on-a-chip (e.g. transporting and sorting micro objects; mechanical components micro assembly...) to in vivo applications for minimally invasive medicine (e.g. targeted drug delivery; brachytherapy; hyperthermia...), due to their micro sizes and accessibility to tiny and clustered environments.

Several kinds of artificial helical microswimmers actuated by magnetic fields have been proposed by researchers. However, they are primarily open-loop controlled, due to the complexity of the control of the magnetic field actuating the helical propulsion, and the limited number of feedback options processing the required precision. Therefore, one of the main objectives of my research is to investigate methods of closed-loop control of a magnetic-actuated helical swimmer at low Reynolds number. A planar path following control of a helical swimmer with 3D steering is realized using visual servo methods based on the real-time visual tracking with a stereo vision system.



8. Rescue robot

Joint intelligent rescue robot, as a handy helper for the rescue crews, could help the rescue crew search and save the suvivors in perilous and sophisticated circumstance, shortening rescue time and ensuring safety of the rescue crews to the great length.

The robot could carry a number of small robots. The multi-combination of these small robot, detemined by specific environment, could provide a variety of solution to multi-task, the environment adaptability of the robot enhanced on a big scale.

In data collection module, environment detection techniques like ultrasonic ranging, infrared ranging, temperature detection, life signal detection, gas monitoring, electronic compass, GPS, sound positioning, digital encoding discs, video capture are integrated by multi-sensor fusion, constuting a integral digital information system. From the data gathered by sensors, the system could not only receive real time position and terrain information, but also provide precious data for exploration and rescue.

Nabao would bark joyfully and dance with the beat of music. There locates three-axis accelerometer, enable Nabao to perceive its current location and orientation. Nabao could stand in right position automatically when it is pulled down. The anxious emotion could be sensed by its unpleasant expression. The vivid movement and bio-inspired function transcend the normal concept of robot.

Nabao is oriented to children, old people and white-collared worker. Children could feed, play and dance with Nabao. Nabao could disperse the atmosphere of loneliness for old people. For white-collared workers, Nabao could alleviate stress and anxiety for its playfulness.

The pet robot Nabao, sophisticated electronic pet, could be virtually a pet for domestic leisure and amusement.

13.Heterogeneous sensing system-based Unmanned Aerial Vehicle navigation

Monocular Simultaneous Localization and Mapping (SLAM), due to the low weight of monocular camera, is an area of popular research and promotes countless applications of micro Unmanned Aerial Vehicles (UAVs), especially in some GPS-denied indoor environments. However, the motion of UAVs is often faster and more complex than that of ground-based robots. It would also lead to error accumulation if we calculate the trajectory only through the ego-motion. The fusion of visual and inertial sensors has proved to be popular in robot navigation and, in particular, UAVs navigation due to its flexibility in weight, low power consumption and cost.
