Crafts for Learning can help you bring simple, low-cost, low-tech robotics projects to your classroom for hands-on STEM learning! This Robot Hand project can be done with students from first grade on up. For younger students, use the printable template; you can also pre-cut the string and straws if needed. Let older students measure out the pieces following the directions, or experiment with different sizes and shapes of hands, as shown in the samples above. The Robot Hand takes 30-45 minutes to make, and costs less than $1 per student.
