My ‘Maker’ nephews’ hydraulic-powered bot built from scrap

This morning my nephews, Nikhil and Shenal, surprised me with a a video of a robotic device they built from scratch.

You’ve probably seen STEM projects that involve making bots or mechanical arms using batteries and sensors. This whatchamacallit does not require electronics. Just cardboard, pins, and syringes.

As a teacher, there are three things I love about this project:

  1. They don’t read off a script!
  2. The commentary is a conversation, building drama (including a mini count down) as the brothers wrestle with the device
  3. Simple explanation of the scientific principles – about levers, the ‘power’, and traction

I like how the claw seems to have a life of its own – good choice of camera angle!

This is what the Maker Space movement encourages, to build, test, fail, redesign, and demonstrate. Their ‘lab’ is their kitchen table!
