The Gripper 3.0 is a precision CNC-machined end-effector design for all of Parallax’s small robots. It is available individually here, and in the Gripper 3.0 12-pack for classrooms.

The single servo actuates the grab-and-lift motion with only a small amount of linear movement. 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).

Parallax’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.

Features:
  • Easy to assemble in less than one hour, following our Gripper assembly instructions web tutorial
  • CNC manufactured from 6061 aluminum in Rocklin, California to provide durable and lightweight performance
  • Compatible with the Parallax small robot chassis for a wide number of uses
Application Ideas:
  • Object retrieval and sorting of many types
  • Simulation of control systems and automation with real hardware
  • Contests using ping pong balls, 3D printed cylinders, wooden blocks, dry-erase markers
  • Use with Parallax sensors to detect objects
  • Ping))) Ultrasonic Sensor for simple location
  • Ping Laser Rangefinder when used in pairs may “center” the object ahead of the robot
  • Pixy2 Camera to identify colored objects, their size and position

Disappointing Quality
I got these floating shelves with LED lights for my wife, and at first, they seemed like a great purchase. She was really excited about them, and they were surprisingly easy to install. Unfortunately, after just two days, the LED lights completely stopped working. It’s really disappointing because the shelves looked great initially, and the added lighting was a nice touch. For the price, I expected much better quality and durability. It’s frustrating when something you’re excited about doesn’t live up to its promise. While the shelves themselves are still usable, the main feature—LED lighting—is what made them special, and that feature failed. I wouldn’t recommend these based on our experience.

LED floating shelves
I love that these have lights. I don't know how they could be designed to hide a cord so are as expected. I wouldn't want them with replaceable batteries either.

Good product!
10/10 would recommend! Super cool and unique. Had a lot more features than expected and good for the price. Super easy to install if you have a hand drill. Very sturdy and not super heavy. Would buy again!

Middle of the road for me. Not great, not horrible.
Size: 10M
Easy to install. Just wanted something simple and inexpensive to liven up my back patio awning. I had them up in mere minutes with adhesive clips. My only complaint is that they are not as bright as one would expect LED lights to be. At night they to me provide more of a soft glow even at the brightest setting. I am not very certain whether they will stand up to hot desert heat. The instructions mentioned adhesive tape on the backs of each light, but there were none on the lights, nor in the box. I used my own. I will update my review after finding out if they do or not. I do like the remote feature however. They are just OK Update**Adhesive tapes were found which fell out of the box onto my floor, which I did not see. My fault. All good now.
