Coming Soon: A New Robotic System That Gives Research and Training A Hand

In the not-too-distant future, robotics research and teaching will take a significant step forward thanks to some new R&D work currently underway in Quanser's robotics division. The research involves having a prototype of a future Quanser product - a small Unmanned Ground Vehicle (UGV) - being tele-operated through a gesture-sensing glove linked to a magnetic tracking system.

This will open up new and better possibilities for robotic control research and teaching. Researchers, instructors and students can expect a deeper, more intuitive experience as well as a significantly shorter learning curve. Essentially, this new system will extend the capability of our UGVs for research and teaching by adding a new layer of gesture-based functionality.

Click below to view the tele-operation in action. As you will see, the kinematics and Jacobian of the arms are solved. The hand motion and gestures are calculated, mapped in a global frame, and transmitted wirelessly to the UGV rover. The arm is clutched with the operator's thumb and his index finer controls the gripper.



At the macro level, here's how the system and glove "fit" together: a magnetic motion tracking system and the gesture-sensing glove have been integrated into QUARC control software functionalities. This high resolution tracking system computes the translation and rotation motions, i.e., roll, pitch and yaw, in a pre-defined Cartesian frame. The data is used to compute a transformation matrix and conveys sufficient information about the operator's hand motion. The glove itself contains strain gauges that capture the operator's hand gestures.

Using QUARC communication blocks, the transformational matrix and the glove data are transmitted to the Gumstix processor onboard the small UGV. Infrared sensors and an RGB camera are some of the other devices onboard the UGV. The QUARC program receives the motion commands from the station PC.

The kinematics and Jacobian mapping motions of the robotic arm are computed and the commanded motions are translated into joint level PWM inputs for the arm. The PWM commands are applied to the servos using HiQ. (The latter is a data acquisiton board specially designed and manufactured by Quanser to be used onboard unmanned aerial vehicles and small unmanned ground vehicles.)

This project is the result of coordinated research and contributions from the Quanser Robotics Team. Amin Abdossalami, R&D Engineer, was responsible for the controls, kinematics and tele-operations. Cameron Fulford, Engineering Manager, Systems & Control, designed the hardware interface and made it a module inside QUARC. Don Gardner did the final assembly of the robot and shot the video demonstration.

The small UGV with glove tele-operation functionality will join the fleet of Quanser unmanned systems in the near future. We're very excited about its ability to offer researchers and students a better tool with which to work and learn.

Growing The Next Generation of Innovative Engineers

Back in the 1950's and 1960's, when NASA's space program was getting off the ground, aerospace engineers' average age was in their 20's. Today, aerospace engineers have an average age of around 55. Ten years from now, those engineers will be retired. So it's fair to ask, "Who will take their place?" That's a question many people in the scientific community, including leading entrepreneur, innovator and founder of FIRST robotic competition Dean Kamen, have posed for some time now. It's obviously an important issue for us at Quanser too, since our major focus is on creating educational products and curriculum for control engineering education.

Are young people sufficiently excited by science education today? It certainly doesn't seem so. Engineering school enrollments are down in North America, and a smaller percentage of students graduate than in past years. The fact is, while it may have been cool to be an aerospace engineer in the 1960's, young people today have largely found their heroes in the world of entertainment and professional sports. They're keeping their eyes on the ball alright, but in our opinion, in most cases it's the wrong ball. Instead of a basketball, it should be a ball bearing in a Ball and Beam experiment!

Our motto is "Captivate. Motivate. Educate." and we bring that spirit to the classroom. Our control products, experiments and curriculum are expressly designed with these goals in mind. Dean Kamen has the same goals. Two decades ago he founded FIRST, an organization dedicated to inspiring young people's interest and participation in science and technology. FIRST is like an all-star game for young science and engineering students, and Quanser is proud to be a part of it. Our engineers are committed to it, acting as coaches for the high school teams and also judging the competitions. This week, March 24 - 26, we'll be doing both in Waterloo, Ontario as 30 teams of the smartest, most inquisitive students in Ontario show us their stuff. Stay tuned for a report on what went on.

We've no doubt that the engineering superstars of tomorrow will be nurtured by competitions and collaborations like these. So while our focus is creating exciting, new, cost-effective university-level engineering education hardware and software, in our spare time we're dedicated to ensuring that the excitement of engineering education is ignited – as early as grade school. That way, we're covering all the bases and preparing more students to be part of the next generation of technical innovators and entrepreneurs.

Watch a short interview with Paul Karam, Director of Engineering at Quanser to find out why he thinks competitions like FIRST are important for students - and for companies like Quanser.

Quanser Expertise Attracts Advanced Motion Research Projects

As part of his latest experimental research, Professor Venkat Krovi, Associate Professor in the Department of Mechanical and Aerospace Engineering at SUNY Buffalo, was looking to develop a prototype of a 6 DOF motion platform. This platform would move over a fixed base and be interconnected by several legs.

To ensure the smoothest possible working relationship and achieve their goals in a timely, cost-efficient manner, Dr. Krovi and his team at the Automation, Robotics and Mechatronics (ARM) Lab engaged Quanser, a world leader in the design and manufacture of real-time control systems.

Dr. Krovi’s confidence in Quanser was based on experience. He’d worked with Quanser’s engineers before as one of the first users of our brand new High Definition Haptic Device HD2.

From the very beginning, the ARM Lab and Quanser spoke the same language. To generate the mathematical basis for the motion platform project, Dr. Krovi‘s team used Maplesoft's MapleSim mathematical modeling software. Maplesoft is a Quanser development partner, and Quanser’s expertise with MapleSim modeling contributed significantly to the speed and effectiveness of the collaborative process.

Equally important to Dr. Krovi was the fact that Quanser management and engineers fully understood his world. As he put it, “The process became very easy when working with Quanser’s team - from engineering through management, everyone was very cooperative.”

He also found that they could devise solutions in a relatively short timeframe. “We were able to quickly nail down the specifications and proceed through various stages of the design cycle which paved the way to the project and its timely completion.”

The entire process - from concept to working prototype - only took two months, less time than normal in a university setting. This allowed Dr. Krovi’s grad students to remain closely involved throughout. The final product ­ the 6 DOF motion platform Quanser developed with the ARM Lab ­is known as the Hexapod, and it is a key part of Quanser’s Mechatronics Controls Collection.

Quanser's Hexapod is a six degrees of freedom motion platform suitable for research in areas such as earthquake simulation, flight simulation and vibration studies.

Like all Quanser devices, the Hexapod is multi-faceted and designed to work in conjunction with other tools to accomplish a wide range of research goals. Currently, at SUNY Buffalo, the Quanser Hexapod is being used in conjunction with the Quanser Haptic Device HD2 to further needle insertion research by helping design a surgical training simulator for biopsy procedures.

- Note: the Hexapod is no longer available for purchase in North America, Europe, Japan and Taiwan. -

Attracting Students with the Cutting-Edge Technology

Research interests of Dr. Youmin Zhang, Associate Professor at the Concordia University's Department of Mechanical and Industrial Engineering spin around avionics, guidance, navigation and flight control of unmanned aerial vehicles. And acquiring Quanser's Qball-X4, an unmanned aerial vehicle system with the OptiTrack camera system and a ground station PC, allowed Dr. Zhang to effectively continue his research in these areas. But Dr. Zhang is also passionate about teaching and sharing the latest research results with his students. With the support of his department, he introduced his undergraduate and graduate students to this cutting-edge technology.

In the fall of 2010, students enrolled in the Flight Control Systems Course were able to use the Qball-X4 for the first time. The Qball system was also used in a newly offered graduate course Fault Diagnosis and Fault Tolerant Control Systems. Concordia University thus became the first academic institution in the world to use such a cutting-edge physical UAV system to teach a flight control course. Dr. Zhang brought his latest research results to the classroom and gave students a chance to get hands-on experience with the unmanned aerial technology. Students could implement a control algorithm they designed on a real unmanned aerial vehicle and test it - something they did not have the chance to do before.

Grade 8 Girls Enjoy Quanser's Ball and Beam Experiment

Every year, Blair McKay, the electronics teacher at Listowel District Secondary School, invites Grade 8 students to his custom-designed electronics lab - eLab. During the electronics workshops - eDays - the students can find out more about electronics and robotics and engage in hands-on activities.

The eDays are held separately for boys and girls. For the girls' eDay, the guest speakers are all women who have exciting careers in electrical engineering, computer engineering and mechatronics. I have been a guest speaker at eDays since 2004. This year, I talked to the girls about how much fun I have working at Quanser, and I showed them Quanser's Ball and Beam experiment. I demonstrated how the computer can control the position of the ball on the beam, and then I let the girls try to control the experiment manually by moving the mouse. All the girls were eager to participate, and although no one was able to control the position of the ball as quickly as the computer, everyone had fun trying!



The eDay workshops are clearly successful at attracting young women to take electronics in high school. At Listowel District Secondary School, Grade 9 electronics is taught as part of an Introduction to Technology class, and there are typically two full all-girl classes!
