Introduction
Make a collision between a robot and a tower. The challenge is very exciting, and fun. Even more fun is possible, if the tower is located at the corner of a table, and the robot runs on a table.
The tower can be made of almost any material, eg Legos, or toilet paper rolls.
Aim
The pupil will learn natural numbers (ie. 1, 2, 3, . . ), and also decimal notation. The integers can be teached using the reverse motion. Also, the notation of aiming to the target is elaborated.
Robot
Almost any robot with wheels will do.
Sensors
No sensors is used.
Example Video
Theory
Exercises
- Let the pupils try and estimate the distances on a different table, without the tower. At the end of the exercise pupils test their distance assumptions.
- If the distance is larger, the aiming of the robot will be more difficult. So, move the starting line farther away from the tower.
- Put the tower at the border of the table, so that if the robot runs too far, it will fall down. Usually the robot will not go broken, even if it drops on a floor from a table, but you may put a pillow there under.
- The green steering block can be adjusted to move according to the time, also. Thus it is possible to estimate seconds, also. Estimate how far the robot will drive in a (eg) 5 seconds.
