Adaptive control for pivoting with visual and tactile feedback

Abstract: In this work we present an adaptive control approach for pivoting, which is an in-hand manipulation maneuver that consists of rotating a grasped object to a desired orientation relative to the robot's hand. We perform pivoting by means of gravity, allowing the object to rotate between the fingers of a one degree of freedom gripper and controlling the gripping force to ensure that the object follows a reference trajectory and arrives at the desired angular position. We use a visual pose estimation system to tra… Show more

“…For modelling and control they assumed knowledge of the object's inertial parameters. In [106] and [107], the authors further use gravitational torque and visual tracking with known object's inertia, to control the in-hand planar motion of an object while grasped by a pinch grasp. In [108] and [109], the authors examined the problem of using the environment contacts to manipulate an already grasped object, defined the dynamics of different prehensile pushing primitives by using the object's inertial parameters, and conducted experiments using simple objects.…”

“…Hou et al studied dynamic planar pivoting of a pinched object driven by hand swing motion and contact normal force control [32]. Viña et al showed that by using adaptive control with vision and tactile feedback, monodirectional pivoting of an object pinched by a pair of fingers can be achieved by changing the gripping forces [33]. Cruciani et al derived a Dexterous Manipulation Graph to plan paths for a parallel-jaw gripper to slide along parallel surfaces of an object from one stable grasp to another [34].…”

“…Επίσης, έχουν αναπτυχθεί ελεγκτικές µεθοδολογίες σύλληψης και χειρισµού αντικειµένου από ϱοµποτικά δάκτυλα οι οποίες ϐασίζονται στην εκ των προτέρων σχεδίαση του σχηµατισµού (grasp planning , preshaping) που ϑα πρέπει να έχουν τα δάκτυλα του ϱοµποτικού χεριού ώστε να επιτυγχάνεται η ευσταθής σύλληψη του αντικειµένου [52][53][54][55][56]. Αντίθετα µε τις παραπάνω εργασίες όπου ϑεωρείται ότι η σχετική ϑέση των σηµείων επαφής δακτύλου -αντικειµένου είναι σταθερή, στις εργασίες [57][58][59][60][61][62] και [63] επιτρέπεται η κίνηση στην επαφή µε το αντικείµενο και η ευσταθής σύλληψή του επιτυγχάνεται µε τα ϱοµποτικά ακροδάκτυλα να µπορούν είτε να εκτελέσουν κίνηση κύλισης, είτε να ολισθήσουν πάνω στην επιφάνεια επαφής. Ειδικότερα στην περίπτωση της ολίσθησης, ακολουθείται συνήθως η εξής µέθοδος : αφού η παραπάνω ολίσθηση ανιχνευθεί µε κάποιον τρόπο, τα ϱοµποτικά δάκτυλα αυξάνουν την κάθετη δύναµη πίεσης που ασκούν στο εκάστοτε αντικείµενο έως ότου επιτευχθεί η ευσταθής σύλληψή του.…”
