Lingkang Zhang

I am a second-year graduate student majoring in computing science in Simon Fraser University. I am a research assistant in Autonomy Lab of SFU. My research focus is Human Robot Interaction and I implement robot behaviors to enable them interact with human naturally. I am also building bio-inspired legged robots and I am interested in using deep learning method to help them walk and recognize objects. Besides, I have been painting for more than 10 years. I also play acoustic guitar, electric guitar and drum sets. My Curriculum Vitae is here.

    Optimal Gaze-based Robot Selection in Multi-Human Multi-Robot Interaction

    This project presents a computer vision based system for interaction between multiple humans and multiple robots. Each human can “select” (obtain the undivided attention of) a robot by simply looking directly at it. This extends previous work whereby a single human can select one or more robots from a population. Each robot optimally assigns human identities to tracked faces in its camera view using a local Hungarian algorithm. Then the system finds the global optimal allocation of robot-to-human selections using a second, centralized, Hungarian algorithm. This is the first demonstration of optimal many-to-many robot-selection HRI.

    Cooperative Behaviour for Model Training with Autonomous Mobile Robots

    In order to gain the benefits of supervised learning techniques without requiring a human to construct a labeled dataset, we have developed a behavior for a pair of mobile robots to train a visual classifier on their own. This autonomous approach takes advantage of the rote nature of dataset creation to allow machines to replace humans with little appreciable loss of performance. A specific implementation of this behavior was written for Chatterbox robots, whose automatically-built dataset was compared to human-constructed ones.

    Orbiting a Moving Target with Multi-Robot Collaborative Visual SLAM

    Towards autonomous 3D modelling of moving targets, we present a system where multiple ground-based robots cooperate to localize, follow and scan from all sides a movingtarget. Each robot has a single camera as its only sensor, and they perform collaborative visual SLAM (CoSLAM). We present a simple robot controller that maintains the visual constraints of CoSLAM while orbiting a moving target so as to observe it from all sides. Real-world experiments demonstrate that multiple ground robots can successfully track and scan a moving target. (video)


    inspiRED Humanoid Robot

    InspiRED is a LEGO-like 3D-printable 70-cm humanoid robot platform featured with highly-customized components. Its controller is a low-cost but powerful single-board Linux computer Odroid-U3 and we use ROS and Open-CV with it. A large number of commonly used electronic equipments including RC servos, camera, HDMI-display, IR sensor, IMU, speaker, microphone, LED, PS2 controller and etc. are supported. We participated in the robotics startup competition, “Ogopogo’s Lair” and won funding support from NCFRN.

    Initial Humanoid Robot

    Initial is a 40-cm humanoid robot. It’s used for testing of running ROS on single board computer, Odriod U3, which talks to a low level controller board for controlling servo motors via serial port. It is also equipped with an HD camera, and the video stream can be transported to the laptop via wifi.

    Intelligent Navigation and Tracking Robot

    It was for Challenge Cup University Students Science and Technology Competition. I was the project leader and covered most of the programming and algorithms designing work. We designed and made the Intelligent Navigation And Tracking Robot in one year. And we ended up with winning the first prize in Beijing and was the only team in my university that gaining the qualification for national final 2013, where we won the second prize.

    Quadrotor Based on STM32 MCU

    I developed a quadcopter based on STM32 since 2013.11. A WLAN Model is attached to its CPU so that it can be controlled by a mobile phone via WLAN. And it is equipped with a video camera to recognize and track certain patterns.

    Rover Based on ARM7

    I developed a rover based on ARM7 in 2013.02. It is controlled by LPC2148, and its position can be detected by using Zigbee equipments which is connected to a laptop which can display it.


    ACM/ICPC 2012

    I studied the basic algorithms and take the programming races on Codeforces and other online platforms. I officially became a member of BJTU ACM/ICPC team in 2012. And I, together with my two teamates, took the Asian zone qualified of 37th ACM/ICPC in 2012, winning a bronze medal finally. (Solved problems collection are in the Algorithm category of this blog.)

    TECO Green Tech International Contest

    TECO Green Technology International Contest is a contest on environmentally-friendly technology organized by TECO Technology Foundation in Taiwan in 2013. Our team’s project, Indoor Localization and Navigation based on Zibee was enrolled in the Internation Final, together with Tsinghua University, Tokio University, Singapore Nayang University, Moscow State University and etcetra.

    • Teaching Assistant for CMPT 125/127 – Computing Laboratory
    • I was the TA for CMPT 125/127 in Simon Fraser University in 2014 fall and 2015 fall. This class teaches the basics of programming in C and C++, with an emphasis on program design and testing. The standard UNIX command-line build and version control tools are used.

    • Help with troubleshooting, setting up, monitoring, etc the telepresence systems.

    • Founder and the 1st President of Beijing Jiaotong University Science and English Association:

    • In 2012, I instituted the Science and English Association in our university, aiming at propagating knowledge and enhancing academic exchange and communication. We held public speaking contests as a premature form of TEDx and look forward to holding an official TEDx in the near future. We also held cocktail parties for the future engineers and scientists to exchange brilliant ideas. We invited a myriads of successful people to give lectures and share their experience.(

    • Vice President of the School Debate Team:

    • I, being the vice president of the school debating team, am deeply in favor of this activity as I find it means more than itself. On the one hand, it enhanced the skills of public speaking, facilitating expressing myself in various occasions. On the other hand, it forces me to think critically and logically, equipping an even more clear mind.

    • Director of the School Students’ Union Office:

    • The School Students’ Union Office is the core of a whole students’ union. Our work was to make plans for different departments of the students’ union so that they could coorperate with each other effectively. And we kept the documentation for all the members and event details of the students’ union.


    • Reading:

    • ‘You are what you read’. Literature, history, economy, politics, phsycology and computer science related books are all I loved. Sometimes, I wrote book notes after reading and some of them are on this website.(

    • Painting:

    • I learnt and practiced sketching at a young age for one year. After that, I drew all kinds of things by myself. Since last year, I started to paint with electronic devices, such as smart phones and Ipad, using an app called SketchBook Mobile. (
