Learning Math/CS/Engineering Design with Robotics
CSP Unit 3 Lesson 8.4
|
In the Lesson 8.3 activities we learned how to call a function with a parameter that had the robot trace a square of specified side length. In this activity we will work on the function definition itself by creating a function that draws an equilateral triangle. The pre-placed function definition block has the name filled in ("traceTriangle") as well as the name of the parameter ("sideLength").

Add code to the traceTriangle function definition that (1) turns on the trace, (2) uses the driveDistance command to move the robot by a sideLength amount, (3) turns the robot left by 120 degrees, (4) uses driveDistance again to trace the next side, and so on for the rest of the triangle. The last command in the function definition should turn off the trace. Then add code to the Workspace that will use driveDistance and turn commands to move the robot to the point (8, 15) and then call the traceTriangle function to draw a red triangle of side length 12 (as shown in blue). |
