View Resource Winch In A Pinch Classroom Activity

In this lesson from Math Machines, students will "construct a function to automate the Pointer/Power Pulley to move a toy truck up a ramp." The class will program a calculator to control a stepper motor. This classroom activity will give students experience constructing functions. They will input the distance the toy truck's operator wants the truck to travel and output the steps the motor needs...

View Resource Motor Tutorials

This website provides tutorials with some animations on topics such as motor principles, phase angle control, pulse width modulation, and power topologies. Students can learn more about DC motors, stepper motors, brushless AC motors and more. These materials could be used as part of an in-class discussion or explored independently.

View Resource Servo and Stepper Motors

In this lesson from Math Machines, students will "compare and contrast hobby servo motors and small stepper motors in terms of the type and range of motion, precision, feedback and speed." The exercise is divided into two parts, the first dedicated to servo motors and the second to stepper motors. Step by step instructions are included for each section. A participant handout (including...

View Resource Sam Come Home! Classroom Activity

In this lesson from Math Machines, students will "use algebra and trigonometry to automate SAM the Robot to complete a right triangular path." The class will use the program SCHOME to perform the task. A participant handout (including worksheet) and facilitator notes are made available for download in DOC file format. Links to the necessary calculator programs are also included.

View Resource Monster 3-D Classroom Activity

In this lesson from Math Machines, students will use the SAM stepper motor robot to follow a path and fire a laser at several cutouts of monsters. In doing so, the class will "calculate angles in the XZ-coordinate plane so that the movement of both the robot (aligned along the Y-axis) and a pointer (aligned along the X-axis) will combine to aim the laser and shoot each monster as the robot passes...
