Thames & Kosmos 620501 Mega Cyborg Hand STEM Experiment Kit: Build your own awesome, wearable mechanical hand that you operate with your own fingers.
Available Options
Dive into the wild world of hydraulics, pneumatics, and robotics with your very own GIANT hydraulic hand—no PhD required! This kit comes packed with over 200 plastic pieces and piston tubes you'll fill with water (yes, just water!) to create a mechanical marvel that mimics the human hand's moves. And here's the kicker: it runs without a single motor or zap of electricity. Once you've built it, slip this futuristic glove onto your hand and control those mechanical fingers like a puppet master. It's got enough grip to lift stuff—think bottles, pencils, or whatever small treasure you can reach. Go on, challenge it!
Oh, and it's not a one-trick pony. Configure it as a left hand, right hand, or go full sci-fi with a claw-like setup (thumb in the center, because why not?). It adjusts to fit almost any hand size, so no one's left out. The 40-page, full-color manual isn't just a building guide—it's a backstage pass to the science of how these systems power industrial robots in the real world. Who knew learning could feel like playing?
- 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.
- Build your own awesome, wearable mechanical hand that you operate with your own fingers.
