About this item

Highlights

  • Build your own awesome, wearable mechanical hand that you operate with your own fingers.
  • No motors, no batteries — just the power of air pressure, water, and your own hands!
  • Hydraulic pistons enable the mechanical fingers to open and close and grip objects with enough force to lift them. Every finger joint can be adjusted to different angles for precision movement.
  • Three configurations: right hand, left hand, and claw-like; adjustable to fit virtually any human hand.
  • Learn how pneumatic and hydraulic systems are used in industrial robots such as automobile components.

Description

Explore hydraulics, pneumatics, and robotics with your very own GIANT hydraulic hand! Using over 200 plastic pieces and piston tubes that you fill with water, build an awesome mechanical hand that uses hydraulic power to simulate the movements of the human hand--no motors or electricity required! Once assembled, your cyborg hand slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers and that can grip objects with enough force to lift them. Challenge yourself to pick up and hold a variety of items like bottles, pencils, small items--anything within reach! The hand can be configured in three ways--left hand, right hand, and claw-like, with the thumb in the center--and can be adjusted to fit virtually all hand sizes. A 40-page, full-color manual guides model building and experimentation and provides engaging scientific information about how pneumatic and hydraulic systems are used in industrial robots to assist with a variety of tasks in our modern world.

Regret this purchase.

This was so disappointing and frustrating for our family. My very capable 9 year old had this high on his wishlist, and I absolutely regret getting it. We ended up throwing it away after 3 days of 2 adults and my son working on it for hours, and it never working.

Enjoying the cybord hand

We did it! If you follow the directions and take breaks as suggested, it can be done. My husband and I took turns with our 8 year old to put it together. My son loves it! All parts are working well!

Not a good toy for kids

Too heavy for the tiny screws that are supposed to hold it together. Broke right away. Did not have a true grip to really do anything with it other than open and close the hands before it broke from just falling onto the table a few inches. Very frail. Just bummed out. Bought it as a Christmas gift and took all that time to build it for it to not last very long.

My 9 year old did it all by himself over the course of 4 days. I only helped start a couple screws he struggled with and with the oil part. Otherwise, all him. So apparently he is gifted based on other reviews! Ha! Only giving 3 stars because a piece going into a tube broke after two days of playing. We are exchanging for a new one, so hopefully this was a fluke.

Worthless junk

Hard to put together, hydraulics are hard to with and piston levers are constantly popping out and are very hard to put back in. Was the only present my kids wanted from Santa and after hours of putting it together is essentially worthless junk.

Don't do it!

Way too hard for a 10 year old, whom is in gifted and talented classes. He's top of his fifth grade class, too. There is no way a 7 year old could do this. Dad stepped in to help and even he is frustrated. Do yourself and the recipient a favor and buy something else.

Bad. Waste of money

No way is this for a 7-10yr old. It took me, a 53yr old with a masters degree, 4hrs to get this together. Plus it’s a piece of junk. The rings where your fingers go pup off too easily. The super small screws were tough to screw in, my 9yr old could not get this done alone.

Clear directions. Very educational. Took a lot of time to build and well worth the end product. I highly recommend.

Difficult all around

Incredibly difficult build. Four plus hours. 10+ years = you got this” is not accurate at all. Difficult to use once put together. Continues to break.

My kid loves it. It took 6 hours to build but if you follow the clear instructions and don’t make the mistake of cutting off required nubs some in the reviews thought were burrs, then it works perfectly. I did all the fingers at the same time. Only complaint is that it does not have a strong grip hold so don’t think you can crush a soda can with it. Overall, a good toy and STEM exercise for the kid.

A million pieces that you have to cut out and terrible instructions. No seven year old is putting this together on their pwn.

Great daddy daughter time

It’s a really great toy for daddy daughter time. His feedback was well constructed and really enjoyed spending time building this together. It did take some time and patience but the end result is worth it.
