Overview:

In this project, student teams design and build a robotic device, which they will use to compete against other teams.  This robotic device will search a 20 foot wide hexagonal area to find a heat source in the least amount of time.  The students will also design the control logic (program) for their devices.  

Learning Objectives or Student Outcomes:

By the end of this lesson, students will be able to work with a team to design and build a heat-seeking robotic device for use in a class competition

Length of Lesson:

This project is generally one of two or three in the semester.  The length of the lesson will depend on a few factors: the amount of in-class time devoted to the project, the out-of-class time deemed necessary by the instructor, and what other activities will be taking place during the duration of the project.

Team Size/Composition:

Teams of four work best; if necessary, a few teams of 3 or 5 students each may be formed. Teams stay together for the length of the project.
 

How is positive interdependence ensured?

Each team is given only one kit, or set of materials, with which to build a robotic device.  Teams must collaborate cooperatively in order to be successful in the project.

How is individual accountability built in to the project?

Each team member is required to turn in a concise written report about the project—the design, the trials, the final outcome, the successes, the failures, etc. 

Basis or Components of Assessment:

1. The actual product and its demonstration

2. A "Design Notebook," which documents the design process

3. A succinct report on the final design that also includes the testing and final outcome of the project

Team Skills Needed for Success:

Students need to have the ability to cooperate, communicate, and collaborate with other group members regarding their ideas and concerns.

Materials Needed by Students:

Each team will be provided a kit.  The kit includes a micro-processor, a bread-board 3.75"x1.75"x0.25", two 60 rpm servo motors, several sensors, all the electrical components to control the servo motors, and a battery pack (2.75"x2.50"x .75") that will hold 5 AA batteries. These components together weigh approximately 0.25 Kg.  Students are not confined to the components in the kit.
