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
Specifications:
  • Power Requirements: 4-6 VDC for servo
  • Communication interface: PWM signal for servo control

Big controllable sound! Buy it
Style: X3206 with One Woofer
Just buy this! It will not disappoint. I bought it for a family reunion gathering in a 5000 square-foot backyard garden. There were multiple seating stations all around and it could be heard from any location without being turned up all the way. Even at the halfway point it is extremely loud. I love that it is waterproof Because I left it outside overnight when the sprinklers came on and it was just fine. The battery charge lasted for five or six hours. It doesn’t take long at all to recharge. It has a good weight to it so it’s not going to blow away, but it’s not too heavy to move around. I use it in the garage. I use it while cleaning. I use it on campsites. It is a fantastic speaker. It is a little large, but not too large that it’s not manageable. I only say that because I have a BOSE small Bluetooth speaker and if you’re used to that small size, this obviously is larger. I have no Bluetooth connection issues with it at all. It plays my Amazon prime music from my phone library perfectly. I would absolutely buy one again. While my BOSE Bluetooth speaker is great, I needed it as an extra boost for a DJ party atmosphere and this did the trick. Here’s a tip, create a playlist on your phone for hours of streaming music or go to YouTube and save your favorite music videos of live music DJs and you have your very own DJ all night.

Best karaoke speaker!
Style: X3206 with One Woofer, Style: X3206 with One Woofer
I was looking to buy a karaoke speaker and all were underpowered or overpriced. This went on sale ~100 and for that price it is THE perfect karaoke speaker. It has dual mic inputs for duets, (4) voice effects, voice echo. Each mic had it's own volume adjustment, there's also adjustment for echo, bass and treble. These are all knobs which i like a lot. The volume is push button which i don't like and would have preferred a knob also . Still, it's a lot of fun for karaoke! What I Iike a lot is the line out. Why? If I feel it needs more power, I can connect to any other speaker with a 3.5mm input. To me this is better than TWS systems that only pair with the same model(s). Speaking of power, it is ok for the size and price. It will sound good indoors at your home or backyard. It may not be the best for a larger hall. But it does have that line-out jack that will let you connect to (almost) any other speaker you want. What I have found lacking so far is the battery life. Fully charged, it was used over BT connection for music at ~50% volume for maybe 1.5 hours with lights and for podcasts at ~15% volume, no lights for 6 .5 hours before it died. So the 14 hour claim must be an exaggeration or only under very specific conditions. Also, bass is adequate, but it's not a 'booming' bass but you can tell it's there. Overall volume is good but will also depend on the device connected.

Great for Karaoke Nights and Small Parties!
Style: X3206 with One Woofer, Style: X3206 with One Woofer
We used the speaker for a recent get-together with around 30 people, and it did not disappoint. The karaoke features and mic input were a big hit, and the party lights added a fun touch. It's super easy to use, and the sound quality—especially the deep bass—is impressive for its size. One thing I really appreciated is the audio-in and audio-out options. If you have a DJ setup, it's super convenient to connect the speaker directly to your deck—no hassle at all. Bluetooth connection took a bit longer than expected to pair, but nothing too bad. Once connected, it worked smoothly the whole night. Great buy for anyone looking for a solid party speaker with versatility!

Terrible sound quality and bass
Style: X5206 with Two Woofers
Sounds cheap, didn’t come with a charger, and the bass does not vibrate at all, so I bought got a jbl 110 the next day. The jbl is a thousand times better, the bass blew me away, and the sound is very high quality. Don’t waste your time and money on it get a jbl
