Big Gripper's "fingers" measure almost 3" long, and open wide enough to grasp a tennis ball! At its widest the fingers open to about 2 1/2" inches. The gripper is operated by an R/C servo, which you provide (most any Futaba or Futaba-style standard-size servo will work). The Big Gripper kit is assembled in under 20 minutes, and requires only ordinary hand tools for construction. All hardware parts are included, along with an illustrated assembly guide.

The body of the Big Gripper is made with rugged but lightweight PVC plastic, custom-machined using computer CNC equipment. You may select from a variety of colors for the gripper body. The "fingers" are molded high impact plastic, and come in black only. To provide you the ultimate in experimenting freedom, you may purchase extra gripper fingers separately.

Mounting holes are provided for attaching Big Gripper to the body of a robot. Or, you may attach Big Gripper to another servo, to act as a wrist. Rubber pads are permanently mounted to the inside fingertips of Big Gripper. For heavier and larger items, especially those with smooth surfaces, you may want to add rubber cushions over the length of the fingers; experiment with materials and techniques. (Suggestions include rubber bands and cut-up nitrile or latex gloves -- the little finger of the glove is just about the right size.)

Big Gripper measures 6" long, 2 3/4" wide, and 1 1/4" thick (with servo the total thickness is 2"). Weight with servo is 3.7 ounces. Lifting capacity is 6-8 ounces, but is conservatively limited by the wrist mechanism you use, if any. Full-open to full-close of the fingers requires approximately 90 degrees of servo rotation.

Currently only available WITHOUT servo. Add your own standard-size servo. See Big Gripper Assembly Instructions for details on compatible servos.
