4. pole interface figure 4 – box containing sigma.7 device, after removal of front foam part Remove the pole attachment interface and power supply before lifting out device from its lower foam block as illustrated in figure 5. While a first person may hold the device, a second person may remove the lower foam block and place it on a table top or any other stable flat surface.

Finally the sigma.7 device base can be mounted on its stand pole by sliding it from the top, as illustrated in figure 8. Place the base at the desired height and lock the mechanism by fastening the clamping screw as shown in figure 9.
(200-240 volt) or low-input voltage (100-120 volt). For safety purposes you should only op- erate your sigma.7 haptic device using the original Force Dimension power supply that came with your device. Replacement power supplies can be ordered directly from Force Dimension.
\manuals subfolder All hardware user manuals are located in that directory. \lib,\include subfolders These directories contain the files required to compile you application with the Force Dimension SDK. Please refer to the on-line programming manual for more information. installing the drivers USB drivers The sigma.7 requires the Force Dimension USB driver.
5. configuring the sigma.7 under Linux installing the software The Force Dimension development folder must be installed onto your system before the sigma.7 can be used. To do this, perform the following steps: plug the Force Dimension USB drive into your system decompress the sdk-<version>.tar.gz file from the drive \Linux subfolder to the de-...
SDK. Please refer to the on-line programming manual for more information. installing the drivers The Apple version of the Force Dimension SDK uses Apple’s native USB drivers, which are in- cluded in Mac OS X 10.4 and higher. No further installation is required.
7. using the sigma.7 device geometry sigma.7 translation axis The position of the center of the end-effector (handle) can be read from the controller. The sys- tem converts the encoder values into (X, Y, Z) coordinates, expressed in IUS (metric) unit. Figure 11 shows the coordinate system.
– calibration is necessary to obtain accurate, reproducible localization of the end- effector within the workspace of the device. The sigma.7 is designed in such a way that there can be no drift of the calibration over time, so the procedure only needs to be performed once when the device is powered on.
Haptic Desk program Under Windows, the Haptic Desk is available as a test and diagnostic program. Haptic Desk allows the programmer to: > list all Force Dimension haptic devices connected to the system > test each device position reading >...
running the demonstrations programs Two demonstration programs can also be used to diagnose the device. The source code and an executable file for each of the demonstration programs are provided in two separate directories named \gravity and \torus. Once the system is setup, we suggest running gravity to check that every thing is working properly and to evaluate your system's performance independently of the graphics rendering performance.
