Teachers will:

Review Sense-Plan-Act (SPA) concept with the class.

Prepare a lesson contrasting the 5 human senses to how robots interpret what’s in their environment

Demonstrate the difference between analog and digital feedback.

Build and attach a touch sensor to tankbot, and demonstrate how the touch sensor works.  Here are several examples of programs using touch sensors.

 

Students will:

Review S-P-A

Participate in a teacher led discussion on how robots use sensors to learn about their environment.

Participate in a teacher led discussion on touch sensors.

Design a touch sensor and attach it to tankbot.

Complete a teacher assigned challenge involving programming and touch sensors.

 

Activities:

Using teacher-supplied instructions, build a bumper for Tankbot that uses a touch sensor.

Program Tankbot with the touch sensor bumper to backup and turn around when it has run into something.

Write a program that lets you control Tankbot using touch sensors as a remote control.

Use touch sensors in conjunction with wait-for statements, program control loops, and touch sensor conditional statements to control design an autonomous robot.
