LUGE FORCE HANDLES

Where the "quality" in "intentional quality" comes to life 

 

The Canadian Olympic Luge team came to us to develop new force handles, much like they saw amongst other national luge teams.

We started with our Intentional Quality (IQ) approach, where "quality" means design management that ensures we are solving the RIGHT problem, as opposed to wasting time and money to deliver a well-designed WRONG solution.  Therefore for Luge Canada that started with an ask to visit the track, talk to athletes AND coaches in order to capture the right KPI's to measure.

What we learned:

While data from the force handles was being collected, that data was sent off-site for data processing and the analysis took several days to return to the coach and athlete.  

 

The "light-bulb" moment:

This lag in data processing time, made it difficult for coaches and athletes to recall specific runs and therefore give the best direction on how to improve performance going forward.  Therefore, because of our approach, the key challenge was identified - reducing the time lag between data collection, data analysis and coaching intervention during training to improve athlete performance. We needed to find a way to get instantaneous measurements with data processing and analysis integrated into a system that coaches could provide REAL-TIME feedback to the athletes.

Problem solved:

We developed a novel system connecting the starting gate sensors over WIFI to an iPad app which integrated data collection and processing with video capture of the athlete, in real-time. Coaches appreciated the media-rich interface to help explain desired interventions. Athletes liked being able to review video and data with fresh muscle memory.

 

...AND THE LUGE TEAM WON MEDALS!

From INTENT TO CONTENT - test driven development put to the test

We were developing a product that would measure wind speed and direction and we reached the phase where the product would need to be tested.  The client would need repeated testing and benchmarking over a long period of time.  

And... 

  • commercial wind tunnels are large, expensive, and difficult to book time in

  • we would need to book several wind tunnel sessions if we went through a third party service

  • wind is difficult to measure outside of a controlled environment

  • we needed to measure the sensor response at a range of angles, which a classic wind tunnel may not support by default

Holistically and intentionally keeping in mind the project objective, scope, deliverables and budget, led us to a clearly defined project roadmap.

 

From INTENT to CONTENT:

While commercial wind tunnels would be cheaper in the short term, using them in the long term would be more costly and would cause issues with testing/bugfix and design iterations.  So we set out to build our own in-house wind tunnel.

Build it and they will come...

The wind tunnel allowed for unlimited access to high quality wind test data. This solution negated large testing timelines and expenses that would come from using 3rd party wind tunnels. The short feedback loop allowed for the best sensor device design we could have achieved.

MOTUS PODIA

New Generation Integrated Sports Measurement System

 

The Podia is an integrated system of body wearable data-loggers, companion modules, and sensors designed by Motus for use in high performance sport analysis.  500hz logging capability, multi unit wireless sample alignment, high bandwidth wireless data transmission, and analog expansion allow extensive configuration options for data capture.  Motus iPad Apps allow on-site analysis of session data combined with video synchronization to provide visual feedback for coaches and athletes within seconds. Motus Review software for PC and MAC provides in-depth post session review of all logged parameters, comparative analysis of multiple session data, synchronization to video and GPS maps, and

custom report generation.

 

Further customization by Motus developers for sport specific applications is available to enhance training session productivity and post training analysis. Podia is also fully compatible with all existing SPIN MMS1 data loggers and force measurement systems.

 

The hub of the system is a data logger module, with a cortex M4 Processor, USB, GPS, Wifi, BLE, ANT, memory LCD display, 4 button UI, and CANbus based analog expansion.  The module is a waterproof,  60g, 6.5cm x 5.5cm x 1.6cm package. A run of 20 units were produced and delivered to Canadian Olympic teams.

MOTUS REVIEW

Analysis Software for Podia and MMS

 

This PC and MAC software was developed by Motus as a companion to the MMS and Podia hardware.  It provides a platform for coaches, biomechanists and analysts for in-depth post session review of all logged parameters, comparative analysis of multiple session data, synchronization to video and GPS maps, and custom report generation.

(MMS)

Instrumentation for Sports Science

 

The MMS was designed by the founding engineers of Motus for SPIN and Own the Podium in 2010 for use by Canadian Sports.  The MMS is a 200hz data logger with GPS, ANT+ and a 16 bit microcontroller.  Companion Review software allowed detailed analysis by coaches of athlete performance.  The system saw extensive use by several Canadian Olympic Sports organizations, and is still in service today.

MOTUS IPAD APPS

Motus iOS apps provide real time feedback to coaches.  The apps sync data from podia data loggers with iPad video for real time review. Providing athletes immediate feedback on recent performance from the captured data enables iterative improvements in performance

ROWING FOOT SENSOR

Innovative strain gauge application

This prototype was developed as a proof of concept to test the feasibility of creating a foot force sensor for use in Competitive Rowing and Canoe Kayak.  Custom transducers with 32 individual strain elements report total x and y forces and center of pressure of force generated by the athlete real time over a CANbus interface.

OAR FORCE HANDLE

Instrumented oars were designed to measure the “output” by each individual rower on the oar and provided valuable data and feedback for coaching.

This “output” included measuring the energy input of the athlete to the boat/crew system throughout a stroke, the rate of work (work/time), and the force describing the interaction between two objects resulting in acceleration (the product of force and time)

TESTIMONIALS

ROK-Software-Logo-Light2.png

Our client required a very short timeline to implement a communication protocol transformation from their system to their customer’s system. Motus Design Group stretched to meet this timeline, providing expert-level embedded software development. Their significant prior experience with CAN protocol proved invaluable.The project was completed on estimate and ahead of schedule.I was very impressed at the high level of initiative and pro-active approach to highlighting and mitigating areas of potential risk to the project.Communications were timely, clear and professional. Meetings with the client were well prepared for and professionally executed which solidified the client’s level of trust in our capability of execution. Throughout the project I was kept involved in the project planning, progress and had a transparent view of the execution.I will gladly work with Motus on future projects.

Motus has been great to work with on our wearable device.The quick turnaround for design prototypes has allowed us to explore many more options in a short time. The ability to see and feel minor changes, and how they impact the user experience results in a better product.

If you are looking for an excellent contract engineering team, I would recommend speaking to the guys at Motus Design Group.We have been using Motus since the inception of our project over two years ago and they have been great to work with. I have primarily dealt with Josh and Jamie and they are both excellent engineers and also very personable and easy to work with. They take the time to explain what they are doing in terms that can be understood by lay people and they also include you in every step along the way.Ours was a research and development project involving a new technology and we had numerous unknowns along the way and Jamie and Josh tackled each challenge in a determined and professional manner and delivered a solution that is going to lead us to commercialization.They are continuing their work on this project and leading our research and development team as we move towards commercialization.I have been very pleased with the entire team at Motus and would not only recommend them to others, I am going to continue to use them as we develop new products and iterations on existing products.
