Robotics

Year Five and Year Six Robotics students have been experimenting with the Lego robotics equipment. They have been coding the EV3 Mindstorms Lego motors to rotate. They have then incorporated various sensors such as touch sensors, colour sensors and distance sensors, and coded their powered machines to activate and deactivate when the sensors are triggered.

Students have also been creating vehicles of their own design, using the Lego Wedo kits. They have been challenged to create a vehicle that can travel at least three metres, using one motor. Many students added a belt to cause a set of wheels to turn with the motor. 

Umaar, Labib and Aayan succeeded in creating an incredibly fast Lego vehicle, which travelled at a speed of approximately one metre per second. This was at least twice as fast as the other vehicles. The secret to their speedy vehicle was their use of gears, rather than a belt, to make the wheels turn. This team of inquirers researched gear ratios and applied this concept to their car. The large cog connected to the motor made the small cog connected to the axle spin several times for each rotation of the motor, resulting in their record breaking design. Brilliant work!
