This is an add-on for the popular Vorpal The Hexapod project. It adds an arm and claw that can be attached to the accessory port and controlled via the gamepad.
Features:
- The arm can raise and lower, bringing the claw all the way down to within a few centimeters (an inch) of floor level or all the way up near the top of the robot's cap.
- The claw can grip objects up to about five centimeters (two inches) in diameter.
- The arm/claw can lift about 120 grams of weight comfortably (about four ounces).
Kit Types:
There are three different kit types to choose from:
- Maker Kit: Includes servo motors, servo extensions, nylon spacers (used as bearings, and screws. Everything you need other than the 3D printed plastic parts. The 3d parts are open source, free downloads. Just search for Vorpal Grip Arm on Thingiverse.
- Complete Kit: Everything in the Maker Kit but also includes all the 3d printed parts in blue ABS plastic. NOTE: if you want a different color, use the notes section of the order form during checkout. Other available colors are Green, Red, and Yellow.
- Assembled and Tested: Everything in the complete kit but it's all put together for you and tested, in Blue ABS plastic. (If you want Red, Green or Yellow then make a note in the notes area during checkout). You will need to attach it to the robot's accessory port, plug the servo wires into the servo driver, and flash a new version of the robot code to make it work with the gamepad. This entire process really only takes about 10 minutes.

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back.
Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.

Actually Cooling Pillow
Size: Queen (1 Count), Color: Original White (Cooling)
This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them.
The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back.
I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.
