The tension between the Gripper plates is determined by a torsion spring which also holds the plates down until the Gripper has closed on the object, with remaining servo motion lifting the object from the surface. The programmer only needs to determine the servos opened\/lowered, closed\/raised position and the rate at which the transition occurs without consideration of the width of the object (provided it fits within the Gripper’s paddles).\u003c\/p\u003e\n\u003cp\u003eParallax’s ActivityBot 360°, Boe-Bot, Shield-Bot for Arduino, and cyber:bot are compatible with the Gripper; robot is not included.  The kinds of objects the Gripper can easily pick up include 3D-printed cylinders, small wooden square blocks, and most lighter things about 1-½” in diameter and up to an ounce in weight. Adding foam tape to the paddles (included) and a small counterweight to the chassis (not included) may increase lift capacity.  Take these parameters into consideration when designing autonomous robot contest rules.\u003c\/p\u003e\n\u003ch5\u003e\u003cspan class=\"forte\"\u003eFeatures:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eEasy to assemble in less than one hour, following our\u003cspan class=\"forte\"\u003e \u003cspan class=\"rotforte\"\u003e\u003ca href=\"https:\/\/learn.parallax.com\/gripper\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eGripper assembly instructions web tutorial\u003c\/a\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eCNC manufactured from 6061 aluminum in Rocklin, California to provide durable and lightweight performance\u003c\/li\u003e\n\u003cli\u003eCompatible with the Parallax small robot chassis for a wide number of uses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cspan class=\"forte\"\u003eApplication Ideas:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eObject retrieval and sorting of many types\u003c\/li\u003e\n\u003cli\u003eSimulation of control systems and automation with real hardware\u003c\/li\u003e\n\u003cli\u003eContests using ping pong balls, 3D printed cylinders, wooden blocks, dry-erase markers\u003c\/li\u003e\n\u003cli\u003eUse with Parallax sensors to detect objects\u003c\/li\u003e\n\u003cli\u003ePing))) Ultrasonic Sensor for simple location\u003c\/li\u003e\n\u003cli\u003ePing Laser Rangefinder when used in pairs may “center” the object ahead of the robot\u003c\/li\u003e\n\u003cli\u003ePixy2 Camera to identify colored objects, their size and position\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cspan class=\"forte\"\u003eSpecifications:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003ePower Requirements: 4-6 VDC for servo\u003c\/li\u003e\n\u003cli\u003eCommunication interface: PWM signal for servo control\u003c\/li\u003e\n\u003cli\u003eDimensions: 3.1 in depth x 3.3 in width x 3.0 x 1.7 in tall (7.8 cm x 8.4 cm x 4.3 cm)\u003c\/li\u003e\n\u003cli\u003eOpening width:\n\u003cul\u003e\n\u003cli\u003e2.0 in (5.1 cm) with no adhesive foam installed on Paddles\u003c\/li\u003e\n\u003cli\u003e1.5 in (3.8 cm) with adhesive foam installed on Paddles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\n\u003cspan class=\"forte\"\u003eGripper 3.0 \u003c\/span\u003e\u003cspan class=\"forte\"\u003eKit Contents:\u003c\/span\u003e\n\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eCNC machined aluminum parts:\n\u003cul\u003e\n\u003cli\u003e(1) Hinge (#720-00027)\u003c\/li\u003e\n\u003cli\u003e(1) Base (#720-00028)\u003c\/li\u003e\n\u003cli\u003e(2) Arms (#720-00029)\u003c\/li\u003e\n\u003cli\u003e(2) Idler Gears (#720-00030)\u003c\/li\u003e\n\u003cli\u003e(2) Fingers (#720-00031)\u003c\/li\u003e\n\u003cli\u003e(2) Paddles (#720-00032)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eLaser-cut parts\n\u003cul\u003e\n\u003cli\u003e(2) Gear Plate (#720-00033)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eHardware parts\n\u003cul\u003e\n\u003cli\u003e(9) 4-40 ⅜” panhead screws (#700-00002)\u003c\/li\u003e\n\u003cli\u003e(1) 4-40 nut (#700-00003)\u003c\/li\u003e\n\u003cli\u003e(9) 4-40 nylon locknuts (#700-00024)\u003c\/li\u003e\n\u003cli\u003e(6) 4-40 ¼” panhead screws (#700-00028)\u003c\/li\u003e\n\u003cli\u003e(4) 4-40 3\/16” flathead screws (#710-00005)\u003c\/li\u003e\n\u003cli\u003e(1) 4-40 1-¼” panhead screw (#713-00052)\u003c\/li\u003e\n\u003cli\u003e(2) #4 stainless steel washers (#712-00011)\u003c\/li\u003e\n\u003cli\u003e(1) 1” Nylon spacer 3\/16” diameter (#713-00031)\u003c\/li\u003e\n\u003cli\u003e(2) Universal “L” brackets (#720-00011)\u003c\/li\u003e\n\u003cli\u003e(1) Universal straight bracket (#720-00012)\u003c\/li\u003e\n\u003cli\u003e(1) Torsion spring, 90 degrees (#725-00022)\u003c\/li\u003e\n\u003cli\u003e(1) Brass rod with ring terminal connector (#725-00027)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eMiscellaneous\n\u003cul\u003e\n\u003cli\u003e(1) 3M Safety glasses (#700-10003)\u003c\/li\u003e\n\u003cli\u003e(1) Super Lube white grease (#700-10019)\u003c\/li\u003e\n\u003cli\u003e(1) Combination wrench -
