Robot ArmWhy is this experiment useful to teachers

and students?

3

It teaches technological design

It requires mathematical calculations

for designIt relates to the studies ofmotion andforce

It requires communication

through writing (design) andorally (explaining the design principles)

Geometry: Use visualization, spatial reasoning, and geometric

modeling to solve problems

Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematicalarguments about geometric relationships

Problem Solving: Recognize and apply geometric ideas in areas outside of

the mathematics classroom

Apply and adapt a variety of appropriate strategies

Communication: Communicate mathematical thinking coherently and

clearly to peers, teachers, and others

Principles & Standards for School Mathematics

We will build a robot arm from simplematerials

The arm must pick up a plastic cupfrom a distance of 45cm

Lift the cup to a height ofat least 15cm

Bring the cup back to rest and release it

Pick up cup upside down

Divide into teams of two (2)

Review the requirements

Discuss a solution and create a sketchof your design

Build a model of your design with givenmaterials

Test your model

Outline and Procedures

Robot Arm

Discuss and agree upon a redesign If needed after testing, or

to enhance the previous design

Rebuild your robot arm

Retest your model

Answer reflection questions as a team

Redesign after testing

What was one thing you liked aboutyour design? What is its main weakness?What is one thing you would change

about your design based on yourexperienceAre there algebraic and physicalprinciples that can be applied to this

activity?How would you modify the instructionsto create a better experience for theparticipants?
