CanadarmTutor is an intelligent tutoring systems developped by the GDAC (UQAM) and Planiart (U. of Sherbrooke) labs. It is designed for training astronauts to the manipulation of Canadarm2. Canadarm2 is a seven degrees of freedom robotic arm deployed on the international space station.
CanadarmTutor offers a 3D simulation of the space station. The user can operates the arm with the keyboard and select cameras and other parameters with the mouse.
CanadarmTutor incorporates several "intelligent modules" to provide tailored assistance to learners. These modules can generate advices, demonstrations, custom exercices, hints, etc.
To design these intelligent modules, several research projects have been carried in CanadarmTutor, sometimes independently. For this reason, there exists a few different versions of CanadarmTutor. This page gives an overview of the version that I have worked on during my Ph.D at the GDAC lab.
CanadarmTutor is implemented in C++ with some modules implemented in Java.
There are four main intelligent modules in CanadarmTutor that allows him to provide intelligent assistance to learners.
Some high resolution pictures of CanadarmTutor can be found here:
Here is a video showing an early version of the data mining module used in CanadarmTutor. In this video, the learner asks what he should do next to move the robotic arm to the goal. CanadarmTutor uses previous learner solutions to recommend actions to the learner.
Here is a video showing the path-planner that was integrated in CanadarmTutor to automatically generate paths that the learner could follow (cf. Belgith et al, 2006).
There have been several articles published about CanadarmTutor. Here, I only mention the ones that I have participated to.

The work that I have done in CanadarmTutor was made possible thanks to (1) the support from my research director and co-supervisors during my Ph.D. (2) grants from the FQRNT and NSERC., (3) the work from many other researchers and students in CanadarmTutor and (3) the Canadian Space Agency who let some students attend the astronauts' training.
