Once students have the basics of how to program their robot to move forward and turn, these next challenges help students gain more skills.
The goal is to get the robot as close to the wall without touching it, as fast as possible, without having the Lego person fall off the robot. Students learn and practice estimating distance in this challenge, i.e., they distance traveled with the number of wheel rotations selected. Decimals may be needed to approach the wall closely.
The challenge is to program the robot to trace the polygon. Programming the robot to follow a regular polygon reinforces understanding of the properties of 2D shapes and incorporates measurement of distance and angles in terms of wheel rotations, which requires multiplication and proportional thinking. We have used this challenge in Grades 3-6.
The Pooper Scooper Challenge is to design and program a PoopBot that can pick-up and dispose fake poop. The robot does not require any sensors. The students are challenged to design and create their arms for picking up and disposing of the fake poop. Make sure your students have time to show the rest of the class their PoopBot and explain how their program works.
The SnowBot Challenge is to design and program a SnowBot that can clear all the snow from the driveway (e.g., a designated space). The robot does not require any sensors. Students are challenged to design and create their own wedge for plowing the snow. Programming requires incorporating measurement of distance and angles in terms of wheel rotations, which requires multiplication and proportional thinking.
