Description

The robotic arm of the future is here! Assemble this cutting-edge, segmented arm from almost 300 plastic pieces and learn how each part comes together in its intricate mechanical design. This innovative system is controlled by a pair of joysticks that pull and release a network of nylon cables threaded throughout, enabling intuitive and precise movements, much like how tendons work to control the muscles in your arm. The result is a mesmerizing motion reminiscent of a cyborg creature’s tentacles in a sci-fi movie! Use the buttons on the top of each joystick to open, close, and rotate the claw 180 degrees. Challenge yourself or your friends to grab, move, and release various objects. Bonus: Switch out the gripper claw with a model of an eel’s head to transform your robotic arm into a slithery bionic eel. A full-color manual guides model building and experimentation and provides engaging scientific information about how this type of robotic arm works while offering up real- world examples.

    • Excellent challenge
As grandparents, we scored big on this gift for our grandson. He enjoys the challenge, having risen above the challenge of even the most intricate Lego products. We will plan on buying similar items for a couple more years.

    • Nice product
Bought as a present for 13 year old who found it interesting and liked it. He went wrong on one of the steps but he worked it out and carried on. Nice quality.

    • Bought it for a grown man haha
My boyfriend is a whiz at puzzles, every year for his bday I try to find an impossible puzzle. Ten years I've been trying and this one finally challenged him. He completed it in one sitting on a rainy day (like 6 hrs) with movies playing in the background, but even he said it was hard. I can't imagine a kid could complete this without help. I'm pretty sure we'll take it to the goodwill, as the toy itself isn't all that entertaining for a 40 something man, but I was giddy that I finally challenged him. Absolutely would buy something like this again! ... show more

    • Fun and thought provoking
My 9 year old son got this for Christmas. Box suggests parental help at that age which is appropriate. He and I have been able to spend time building together

    • Very cool
Be prepared, this is not a quick build! It takes multiple sessions especially if you’re working with a younger kiddo who loses interest or doesn’t like to sit still. It took about 8 1 hour sessions with my 8 year old but it was well worth it! He had a blast doing it and once it is done it’s really cool to play with. All the parts are there and the instruction manual is VERY detailed with descriptions and pictures for every step. This helped a lot for my kid. The kit is very educational and definitely teaches them some skills. Good price too! ... show more

    • Great stem but not easy to build even adult help.

Great stem and idea but not easy to fit on even with adult help. Me and my boy manage to finish setting up but not working. We had our fun but I am lazy to dissemble to solve the problem.
