Brahim Tamadazte, Sounkalo Dembele, Nadine Le Fort-Piat
2008 2008 International Workshop on Robotic and Sensors Environments  
The paper deals with the modelling and calibration of that kind of imaging system. A multiscale calibration paradigm is proposed and validated by means of a commercial video microscope.  ...  At the end, the model is used to perform a visual servoing whose purpose is the aligning and centering of a micropart with a gripper.  ...  Application to Visual Servo Control As exposed above the calibration parameters are used to perform the task of aligning and centering a part with respect to a gripper by visual servo control.  ...

Robotic micromanipulation for microassembly: modelling by sequencial function chart and achievement by multiple scale visual servoings

Brahim Tamadazte, Nadine Le Fort-Piat, Sounkalo Dembélé, Guillaume Fortier
2009 Journal of Micro-Nano Mechatronics  
So, the usual visual control law is modified in order to take into account this relation.  ...  The latter includes a robotic system, a gripping system, an imaging system, and a clean environment. The imaging system is a photon videomicroscope able to work at multiple scales.  ...  Thanks to motorized zoom and focus of the photonic microscope, dynamic and multiple scale visual servoing is proposed.  ...
