It is required to install the RoboDK TwinTrack Add-in and have a supported measurement system to use the TwinTrack tools.

Make sure to have the following:

1.One or more industrial robot arms.

2.A supported measurement system (6 DOF). Supported measurement systems include:

a.HTC Vive Trackers (SteamVR)

b.Full Virtual Reality kit (SteamVR)

c.Laser tracker with 6 DOF capability and supported RoboDK driver

d.Creaform C-Track

e.OptiTrack Camera system (it is recommended to use 4 PrimeX13 for best accuracy)

Note: Compatible measurement systems are not included with the TwinTrack license. RoboDK does not manufacture or sell measurement systems.

Important: HTC Vive Trackers or Virtual Reality base stations are not made for accuracy. The best accuracy results are obtained with proper metrology systems such as a Laser Tracker.

1.RoboDK software must be installed and an appropriate license for TwinTrack must be installed.

2.You need compatible robot drivers for your robot controller if you want to automatically run robot programs.

3.Install the TwinTrack RoboDK Add-in:

a.Download the TwinTrack Add-in (.rdkp file).

b.Double click the file to install the Add-in and open it in RoboDK.

c.If you don’t see the TwinTrack menu: select Tools➔Add-in Manager and double click on TwinTrack to see the TwinTrack menu on the top right.

Note: RoboDK Add-ins require the Add-in Manager to be enabled. This plugin should automatically be loaded when opening the TwinTrack rdkp file. If it is not the case, refer to the Add-in Manager documentation.

Setup with SteamVR and HTC Vive Trackers

This section guides you through the steps to configure SteamVR. You can use a custom-made tool with a tracker to mimic your manufacturing operations with your hand so your robot can replay the same motion.

RoboDK TwinTrack supports Virtual Reality systems and all trackers supported by SteamVR, including HTC Vive Trackers from v1 to v3.

Note: HTC Vive Trackers are the most affordable solution to use RoboDK TwinTrack. A full system with two trackers and 2 Valve Index Base stations can cost under $2,000 US. A tracker can be attached to a custom probe or tool to mimic the manufacturing operation by hand.

Important: While you can use HTC Vive Trackers for industrial purposes to simulate and program your robots, this system was originally designed for gaming purposes and not accuracy. If you are looking for accurate results you should use a more accurate measurement system such as a laser tracker.

Important:As of April 2024, RoboDK provides a standalone SteamVR installation, that removes the need to install Steam and edit the SteamVR configuration files: https://robodk.com/downloads/private/SteamVR-TwinTrack-v1.27.5.zip. If you are using the standalone version, you can skip to step #4.

Follow these steps to configure your SteamVR system for TwinTrack:

1.Install Steam if you have not done it yet, you may need to create an account with Steam.

2.Install SteamVR, this is a Steam extension that adds support to Virtual Reality and 6D Tracking.

3.Remove the need to have Virtual Reality headset if you don’t have it or you don’t need it by following these steps:

“forcedDriver”: “null”,    (default is empty “”)
“activateMultipleDrivers”: true,    (default is false)
Close SteamVR and open again.

4.Open SteamVR and follow the instructions to set up your system. You can accept all default settings if you are not using a VR headset.
