Educational standards

NGSS MS-ETS1-4 Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.CSTA 2-CS-01 6-8 Recommend improvements to the design of computing devices, based on an analysis of how users interact with the devices.Common Core CCSS.MATH.CONTENT.7.G.B.4 Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.

Learning Targets

Use motors to manipulate your environment.

Success Criteria

Students can use the Ultrasonic Sensor to detect and and respond to an object.

The Right Tool for the Right Job

Motorized tools can be attached to robots to enable them to perform different tasks. Some are very specialized and optimized for a single purpose, whereas others are more versatile.

Human Robot

Can you tell a partner how to pick up something for you by only giving them simple commands? Work in a team of at least 2 people. Blindfold one team member and place a hand-sized object within arm's reach. The other team member must give very simple but specific commands. They may not give commands such as "pick up the object." Use commands for each movement such as "bend your arm at the elbow" and "open your fingers."

Questions to Ponder

What tasks should a motorized tool designed to handle objects be able to do?
In which situations would you choose a highly optimized motorized tool?
In which situations would a versatile motorized tool be better?
