Description: This robotic claw is a step up from the classic. The MKII takes everything you loved about the standard robot claw from DAGU and makes some significant improvements!
Just like the classic claw, they are made from metal and are pretty heavy-duty, but the MKII also features brass sleeves in the joints which make them more rigid and less likely to come loose. The claw opens to about 2" and depending on the servo motor used, it can pick up some relatively heavy objects. The new spring-loaded clutch helps protect your servo gears from damage and also increases the gearing to 2:1, allowing the servo to act over its entire range and provide more gripping power!
These also have a mounting plate on the bottom which accepts standard spacing found on servo mounts (the extra bits that come with our servo motors). These do not come with a servo motor, so check below, the ‘micro servo’ is the one that works well.

This is a pretty good mechanical gripper. It’s made of stamped aluminum and weighs about 6 ounces (.17 kg) with the recommended-sized servo. The clutch is a nice feature - it reduces the chance of damage to the servo but also limits the gripping power. It’s a little difficult to insert the servo and clutch without some disassembly, but can be done.
Yes, the linkage is a little loose and it’s not extremely robust, but it wouldn’t cost twelve bucks if it was something that C3PO would be proud to own.
Seems like one of the stronger options available, but I didn’t read the description close enough and bought a standard sized servo. My mistake. I went to the hobby store and bought a Hitec HS-85BB micro servo. The horn uses a different screw, so I had to drill and tap it to get it to work.
A team project for my university needed a robotic gripper from our own budget. This model was relatively inexpensive and the clutch is a big benefit compared to other options at the low range. It is a great claw for the price and meets everything we need. Just be warned that it may take a couple tries to get the clutch set properly (the magnets in it can stop the whole device if not set properly), but it has been working great since.
My son and I are building a robot in slow steps, dictated by what we think would be cool at the time. We thought a claw would be cool, so we got this one. It was easy to put together and works well, except for a slight unevenness in the operation; the gears are slightly irregular at one point. It seems pretty sturdy, at least for the things we would like to do, and we’ll have fun writing programs for it. For hobbyists, it’s great.
