Engineering / Systems Overview
This page gives some information about how Codamotion products work. To see some example configurations which may be appropriate for your needs, please see our Example System Configurations page.
Codamotion CX1
The core movement analysis technology of the Codamotion system is the Codamotion CX1 unit. A single unit is able to measure the locations of active markers in 3D with high resolution and accuracy. Being an active system, markers are identified electronically by the hardware so that no post-processing is required to label the markers. The viewing angle of a CX1 unit is very wide (approx 80 degrees). Multiple units may be combined to give even greater capture volume and minimise occlusions. The units are pre-calibrated in the factory, so no on-site calibration process is required. A single cable connects power and data transmission to each unit, making the system very quick to set up in different locations. A system of multiple CX1 units may be split into smaller sub-systems so different projects can be worked on simultaneously.
Active Markers and Drive-Boxes
| Codamotion markers are tiny infra-red LED's. These are powered by small drive boxes, placed close to the LED on the limb. No wires should ever need to cross joints or impede the movement of the subject. There are no tethers to the subject so their movement is completely free. When not in use the drive boxes are stored in convenient battery charger trays. A single charge is enough to last for several hours of uninterrupted capture. |  |
Hubs and A:D Interfaces
To record and analyse 3D movement data from the CX1 units, a single cable from each unit must be connected to a Hub. Hubs are available in two varieties. An Active Hub is a host computer with built-in connections for multiple CX1 units. A standard hub supports up to four CX1 units, and can be extended to allow even more. Analogue inputs and digital input/output can also be fitted to an Active Hub. Alternatively a Mini-Hub allows connections of up to two CX1 units to a standard laptop PC.
Integration with Other Devices
| Codamotion supports a wide range of other devices for direct integration, including force platforms and EMG systems. Complete laboratory systems can be supplied. Analogue interface of 32 or 64 channels allows synchronous acquisition of any device with suitable analogue outputs. Optional force acquisition modules include computation of force reaction vector and centre-of-pressure. |
