Robot interface

Robot module overview

The robot module is an interface over real or simulated robots.

The source code documentation shows which are the corresponding classes part of robot module.

This module uses optional third-party libraries to enable some capabilities. settings

Real robots interfaces working everywhere

  • We propose also a wrapper over Haption Virtuose API to enable the control of their haptic interfaces. All Haption hardware products support the same low-level driver called Virtuose API, which provides access to all functions of the haptic devices. The wrapper implemented in vpVirtuose class allows to control Virtuose, MAT, Inca, Able family products.

Real robots interfaces working only at Inria

Since the low level drivers of these robots are not open-source, the following robot interfaces can only be used at our lab. For those who want to interface their own robots, the corresponding classes implemented in ViSP could give a good idea on what has to be implemented.

Simulated robots

ViSP provides several robot simulators. Some of them are based on real robots such as Afma6 or Viper s850.

Free flying camera

This simulator is pure virtual. Indeed, it represents a free flying camera. There is no joint limit, no singularity. It can be useful to test a new control law and test its convergence. The ViSP class which implements this simulator is named vpSimulatorCamera.

Real robot simutators

We exploit among other an Adept Vider s850 six dof arm and an Afma Robotics gantry robot called Afma6. These real robots can also be simulated. During simulation, their behaviors are as closed as possible from the reality as shown in the following video. As the dynamic model is not taken into account here, there is a shift between the velocity of the robot and the velocity of the simulator.

The visualisation is based on the wireframe Simulator able to produce an internal and an external camera view. The following video presents a simulation of a visual servoing experiment. The internal image is used to compute the control and then bring the camera mounted on the robot from one position to a desired one.

The two classes that implement these simulators are vpSimulatorViper850 and vpSimulatorAfma6. The following pictures present the Afma6 simulator next to the real robot.
