Front motor could halt because it could not complete the turn. Students could get confused. Where exactly is the problem?
Here are a couple of notes for this problem and generally how to conduct the class with the Dragster.
Front motor could halt because it could not complete the turn. Students could get confused. Where exactly is the problem?
Here are a couple of notes for this problem and generally how to conduct the class with the Dragster.
For the task "Make the robot turn 90 degrees." students are expected to program the robot to turn the front wheels and then move forward until the robot turns to a full 90 degrees.
Students could try to put the robot on the floor with the front wheels that are already turned. This is not an accomplished task.
The robot program will half if the motor turn is set to degrees or rotation that can not be executed. The motor turns could be programed in seconds and in this way the program will not halt. Give the students time to experiment and find the problem on their own. Then brainstorm together on a solution.

This Tutorial is used in the following courses and lessons
The third level of the Robotics with LEGO curriculum for students in second, third or fourth grades.
In these lessons, we stress on more complex and challenging robots. The concept of Condition is introduced. Students learn about physics concepts of inertia and center of mass. Robots with two sensors are built and students program both of them. Programming becomes more complex as robots now can make complex decisions. "Spy"-robots sneakily follow their targets, trying to be undetected.
For students who will not take two levels in a row today is their last lesson.
