Students will learn that everyday tasks that seem easy to us are difficult for a mechanical robot to perform. Students will investigate this by using a robotic toy hand. As a class we will discuss the limitations and challenges that robots face in grasping tools and manipulating them. To conduct this lesson you will need to purchase up to 12 or 14 robotic toy hands. This can be purchased at Toys R Us for about $7(Australian dollars) each. There are plenty of youtube clips that you can show the students prior to the investigation that cover the use of robotic arms in industry and on the ISS. Once you have your equipment then you can use the powerpoint to guide the students through two investigations. Part 2 and Part 3 of this package is the worksheet to accompany the investigations.
