Robotic Arm

Fluid Power


So we made one to give an opportunity to see how levers work and are applied in a cool machine.

Lifting materials horizontally is important in some places, where an item has to stay level, so with a parallel linkage the gripper stays horizontal.

Usually robotic arms grab and move things from one place to another, so this moves about 90 degrees, (along with the up and down).

Similar machines can be made with the class pack, we’ll show you how soon, but you should try to figure it out yourself!

We have free plans for a robotic arm, that you can make with the class pack, but they can be made in many styles, so don’t be afraid to experiment!

Here is a link to The Learning House - they made a short video on how it works on their facebook site - very accurate movement!


Robotic arms are widely used around the world (and in space- the Canadarm!)

Our Robotic arm moves in three ways, using 6 syringes. Can you tell which types of levers there are?

STEM activity teacher ideas

One of the great things about STEM initiative, is that it is interdisciplinary, and promotes enquiry-based hands-on learning. This kit is designed to help kids work together in teams and learn about Science, Technology, Engineering and Math, in a hands-on manner, introducing them to levers, understanding how robotic arms work, considering engineering concepts in its design, and all the math of predicting outcomes with applications in the real world.

If doing a fluid power, robotics, engineering design process,  or simple machines research and design unit this is a great place to start. This arm kit can be a nice lead-off activity for students by having them make the kit and consider its uses and actions, manoeuvrability, and applications in the real world. Ideally students work in small groups and then are given an activity to test their teamwork and coordination.

Students can research how and where robotic arms are used online, and also consider the different applications of machines that lift and turn.

Other considerations in preliminary research might be to learn about how hydraulic machines work, best designs and learn about how and where they are applied. There are bunch of hydraulic machines videos in this site! (look at the videos link above).

We will be adding pdf lesson plans and teacher suggestions soon!
