DeltaBot™ User Story , IEEE robotics webinar

Newsletter for December 2010

High-speed robot, DeltaBot, designed using Maplesoft Technology

Dr. Amir Khajepour did not realize how much industry demand there would be for his robot when he first began to design it. The original design was done as part of an advanced research project involving high-speed robots, conducted at the University of Waterloo (UW), and used Maple™ to develop key elements of the design. Following the completion of the DeltaBot, a robot based on an innovative cable-actuated delta-style design, Dr. Khajepour received a surprising number of requests from industry for its use. Based on this commercial demand Dr. Khajepour established AEMK Systems (, a company specializing in the design and distribution of high-speed, cable and vision-based robotics systems for use in a variety of industrial applications.

Early in the initial research phase, Dr. Khajepour chose Maple, Maplesoft’s advanced technical computing software, as a key tool in the UW robot research project. All subsequent design improvements and enhancements to the Deltabot system were developed using Maple and MapleSim™, Maplesoft’s high-performance physical modeling and simulation solution.  Maple and MapleSim are built on a foundation of advanced symbolic computation technology, which lets users obtain highly accurate results.  Maple and MapleSim provide insight into the problem structure, allowing users the flexibility to quickly develop ideas and conclusions about the system behavior.  “Maplesoft technology was an integral part of the design process of the DeltaBot system, and is now an integral part of the robot’s ongoing development,” says Dr. Khajepour, President and Founder of AEMK Systems, and UW Professor of Mechanical Engineering. “With the use of Maplesoft technology, the initial development time for the robot was significantly reduced, and we continue to benefit from shorter development cycles as we make enhancements to our products.”

IEEE Webinar: Highly Efficient Models of Multibody Systems for HIL Simulation of Robotic Systems

Thursday, Jan 27, 2011, 2:00 PM ET

This webinar presents techniques and applications for rapidly developing computationally optimized models for HIL simulation of high-fidelity physical plant models. Using symbolic computation techniques, multibody models can be effectively preprocessed to select optimal coordinate frames, eliminate redundant calculations, simplify algebraic constraints, and generate computationally minimal code for real-time deployment. Furthermore, novel mathematical techniques can be deployed for efficient parameter optimization and other advanced analysis. Applications in robotics, including space and industrial robotics will be presented. The symbolic computation system Maple and the related modeling system MapleSim will be used to illustrate examples. This webinar consists oftwo parts:

Part I:
General survey of techniques and applications of symbolic computation
techniques in robotics.
Part II:
Applications in space and industrial robotics.


Dr. Amir Khajepour, President AEMK Systems, Professor, Mechanical Engineering, University of Waterloo, and Canada Research Chair in Mechatronic Vehicle Systems: Dr. Khajepour is an authority in mechatronics and robotics. His research includes modeling and development of advanced systems for the automotive, space, and manufacturing industries.
Dr. Tom Lee, Vice President Applications Engineering and Chief Evangelist, Maplesoft: Dr. Lee is the principal technology spokesperson for Maplesoft, an emerging leader in advanced engineering modeling and simulation. As Vice President of Applications Engineering, Dr. Lee directs the principal engineering engagements for Maplesoft, including custom model development, consulting, and training, with key customers and partners. Dr. Lee holds a Ph.D. in automation and control and has been a leading influence in the development of new modeling tools for physical modeling and symbolic

Science Fiction Double Feature
Dr. Tom Lee
Like many in the technology industry, I am a big fan of science fiction films and I’ve written in the past about how exciting it is for me to have a job where science fiction and reality literally meet. Over the past few months, several key projects from various Maple and MapleSim users caught my attention for various reasons and once again, I was forced to giggle publicly as the shear cool factor of these applications overcame my normal mature demeanor.  Read More>>
Green Cars
Dr. Tom Lee
It’s ironic that my life in North America started with a green car and has come full circle with green cars all over the place as far as my job is concerned. But of course, today’s green car is really about highly fuel efficient cars or cars powered by entirely difference energy sources than with the old Skylark.  Read More>>

Application Center Highlights
Santa's Sleigh Ride
Author: Maplesoft

With the holiday’s right around the corner, there is a festive vibe going around the office. Decorations have been hung, lights have been strewn, and we’ve just had our first snow fall of the season. Our application engineering group has also got in the spirit and modeled a flight path of Santa on his sleigh. Using MapleSim, they’ve created a simple flight path for Santa and have modeled the effects his body would experience as he is flying through the night sky. You can watch a video of it here. Granted this doesn’t have all the features, like the weight of his bag of toys, or the aerodynamic effects 8 reindeer would have on his flight, but it’s a good starting point.


The Physics of Santa Claus
Author: Maplesoft

For a number of years, just before Christmas, an article explaining the physics involved in Santa's Christmas Eve trip has circulated the internet. It is re-created here, this time with up-to-date values, and of course, using Maple.

Maplesoft In The Press

Here are some highlights of this past month press coverage.

MapleSim Helps Improve Your Golf Game
Product Design & Development, November 30, 2010

Extract: "The speed of all most computations has been increased by more efficient algorithms. The new Maple Cloud Document Exchange facilitates the creation, distribution and exchange of documents with colleagues. Of course all of our old friends such as the TA’s, Tutor’s, Help Database and extensive mathematical algorithms are still there, as are the very useful palettes. The many application briefs and add-ons available on-line complete a very nice package for the student, engineer or industrial mathematician."
Simulating continuous models with discrete events
Engineer Live , November 18, 2010

Extract: "Maplesoft is releasing Maplesim 4.5, the latest version of its high-performance physical modelling and simulation tool. Based on advanced symbolic computation technology, Maplesim is an engineering software tool for design, modelling, and high-performance simulation, including real-time and hardware-in-the-loop applications. Unlike traditional, numeric-based modelling tools, the symbolic approach of Maplesim exposes and provides access to the model equations."
