Funny and practical soft grippers designed for gripping soft and fragile objects as well as objects of complex and simple shapes.
Made it from improvised materials: silicone sealant, a couple of fabric, and a couple more things.

Grippers are modifiers for the meArm robotic arm, which has bugged everyone, and are presented in two variations with three fingers for gripping relatively large objects of a rounded shape and with two fingers for gripping small objects.

The grippers' fingers are made from silicone sealant, but you can use molded silicone.

The gripper is placed on the most popular printed mearm robotic arm (https://www.thingiverse.com/thing:101.... Anything can be installed as brains for it: arduino, orange pi, raspberry pi, etc. of your choice

List of main parts:
acid silicone sealant (the softer the better) or molded silicone;
a piece of fabric for reinforcing fingers (plain cotton can be used);
dropper (tube from it);
syringe 20ml or 10ml;
motorreducer N20 12V with good torque, but not very slow;
two nails d=4mm, l=120mm. as guide shafts. (It's necessary to cut off 98mm from them).
stud and two nuts M6 as lead screw and nuts;
driver motor ln298 or other 12V;
two optical or conventional limit switches;
