1.1.Grippernomenclature

The2-FingerGripperhastwo articulated fingersthat eachhave two joints(two phalanxesperfinger),asshown inthefigurebelow.The

grasp-typegrippercanengageup to fivepointsof contact withanobject (two on eachof thephalangesplusthepalm).Thefingersare

under-actuated,meaning theyhave fewermotorsthanthetotal numberof joints.Thisconfigurationallowsthefingersto automatically

adapt to theshapeof theobject theygrasp and it also simplifiesthecontrol of thegrasp-typegripper.

1.3.Object picking

The2-FingerGripperhasasingle actuatorfor opening and closing thefingers,thefingersautomaticallyadapt to theshapeof the

object manipulated.

Fingerswill adopt eitheraparallel grasp orencompassing grasp asshown inthefigurebelow.

Info

Closing oropening isdoneviathe"Go to requested position" command and isinput to theGripperWhetherthe fingers

close to produce anemcompassing orfingertip grasp isdecided at the Gripperlevelautomatically.It will depend on:

lTheobjects'sgeometry;

lTherelativepositionof theobject with respect to theGripper.

In otherwords,picking thesameobject could result ineither anemcompassing orfingertip grasp based onanobject's

positionand geometry.

Fig.1-3:2-Fingerparallel and encompassing grips.

Info

It isimportant to notethat a fingertip grasp canonlybeperformed whenthefingerstouchtheobject with theuppersection

of thedistal phalanxesfirst.Inversely,for anencompassing grip,thefingersmust touch theobject withtheproximal or the

lowersection of thedistal phalanxes first. Also,to ensure stability,theobject should be held against theGripperpalm while

performing anencompassing grip.Referto thefigure belowfor avisual representation of theparallel and encompassing

grasp regionsonthedistal phalanxof the2-FingerGripper.
