UNIVERSITY OF WATERLOO - NOTICE OF INTENT TO AWARD A SINGLE SOURCE CONTRACT: #17-081
3D Measurement System
The University of Waterloo (UW) intends to purchase an Optotrak Certus 3D Measurement System from Northern Digital Inc., of Waterloo, ON, Canada. The 3D measurement system will be used to accurately track human movement and movements of objects in experimental settings.
This is an advanced Notice indicating to the supplier community that UW intends to award a contract for these goods to a pre-identified supplier. If no other supplier submits, on or before the closing date of this notice, a statement of specifications that, at a minimum, equals or exceeds the stated requirements set out in this Notice, the competitive requirements of the University are considered to have been met. Following notification to any suppliers not successful in demonstrating that their statement of specifications meets the requirements set out in this Notice, the contract may then be awarded to the pre-identified supplier.
If other potential suppliers submit statements of specifications during the fifteen calendar day posting period, and meet the requirements set out in this Notice, UW will proceed to a Request for Proposal process, in order to award the contract.
BACKGROUND:
The 3D measurement system will be used for understanding mechanics, energetics and control of normal and pathological movements. The 3D measurement system will allow for:
- Accurately tracking full body movements of one or more subjects in a large space.
- Controlling aspects of the experiment in real time, based on current movement.
- Tracking objects that subjects interact with.
- Tracking the response of in-vitro specimen to forces and displacements by a robotic actuator.
- Synchronizing 3D measurements with other data sources.
Because of the expansion of our research activities to various locations on and off Main Campus, additional 3D tracking capacity is required that is compatible with the existing 3D tracking systems at the University.
PROPOSED SOLUTION:
This flexible, scalable system accurately captures the 3D position of up to 512 infrared LED markers. Each position sensor has a fully calibrated capture volume. Position sensors are manufactured and factory calibrated to NIST traceable standards by the ISO certified manufacturer. 3D position data is reported for each individual marker sorted, unfiltered and in real time, without altering the frequency content of the signal. With an accuracy of 0.1mm and resolution of 0.01mm, it is accurate enough to derive acceleration patterns from unfiltered position trajectories. This system operates completely in the invisible IR spectrum, and can be used for experiments conducted in the dark. It also comes with a unique tetherless marker setup: lightweight LED markers designed for minimal inertia artefact (smart markers) that can be daisy chained in branching chains to maintain the freedom of movement of the subject. The system also tracks and reports the position and orientation of marker clusters (rigid bodies) and digitized points. The marker set (individual markers, clusters, or a combination of both) is completely customizable to meet the needs of every experiment. The system offers a range of analog input and output options, used for integration with other research equipment.
The proposal from Northern Digital Inc. includes essential components as follows:
