Kids Club: Child reporter Diego builds a Hydraulic Robotic Arm

You may well remember me as the little scientist who has created videos to teach kids how to learn science in a fun way. As part of that and also trying to learn some engineering skills I have now built a Hydraulic Robotic Arm using a special kit. Here is my handwritten review. Boys and girls alike will both enjoy this educational toy and will learn lots about the physics behind a robot.

Watch the video here: 

he Hydraulic Robotic Arm kit includes a 3 dimensional model demonstrating a hydraulic power system. The arm function uses some of the same principles that drive real world machines; it can lift small items horizontally and rotate 90°. Made from die-cut plywood, the frame is precisely cut and can be assembled in at least 2 hours – if it’s done by a 8 year old child. Standing at 37cm high, and stretching up to 49cm, the hydraulic arm needs no battery, simply add water to put it to the test!
