In the taskĀ "Put the truck on a stand, so that its right wheels touch the ground and the left ones do not" the students are expected to build the stands themselves. A stand could be any object that the robot could be put on, so that the side of the robot with the left wheels would be in the air.
In the task where LEGO parts are put into the lid of the LEGO Mindstorms set's box, make sure a student won't turn his/her box over himself/herself. All parts have to be into the lid and all lids should be put on the ground, where the robots would be moving. The robots have to start moving outside the lids, then climb onto the lid, move through the obstacles in it and exit from the opposite side. If the trucks have difficulties climbing the edge of the lid, you can allow students to start the trucks directly into the lid.
For the bonus task "Make a cargo caring truck competition" all lids can be arranged one after another and trucks can be started one by one as you measure their time. This bonus task is done only if all the students have finished the main tasks in the lesson. Otherwise, let the students figure out how to compete.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons

Level C1. "Transportation". Robotics with LEGO
This is the fifth level in the Robotics with LEGO curriculum for students in third or fourth grade.
For the first time robots with steering wheels are built in this level. Those robots use one or two drive motors. The work of the differential and its usage in vehicles is explored. Students learn in-depth the working of the light sensor to create better line-following programs. The first two-wheeled motorcycle-robot is built.

Lesson 2 - Off road truck
Introduction
In the previous lesson we've learned that the wheels of the car are rotating with different speed when the vehicle is making a turn and that is the reason they cannot be connected to the same motor. But what if we connect only one of the rear wheels with the motor and we leave the other one free?
Today we're experimenting with a truck that is designed to transport cargo through rough terrain. The focus here again is on the construction. Hopefully, you've learned to park in the previous lesson, because you may need it again!
