This is an attachment for the top of the robot and the attachment is used for lifting different parts. It is reusable as we could change the lever and use the attachment for a number of different missions.
We use this attachment to demonstrate the principle of an active attachment. This is an attachment activated from the motor. It has one level attached to it. It could be reused. The attachment transfers power from the motor to the end of the lever and we can accomplish missions like the Power Switch mission from the FLLCasts Off-season mission models.
The new Spy is a robot with tank treads, which uses one medium motor to turn three things at once. That is achieved by a gear system. Simultaneously the robot turns its two hands up and down, but in opposite directions and its head - left and right.
The robot moves with the help of two tank treads, attached to two Large EV3 Motors.
This is a Camel-like robot. We demonstrate an interesting use of gears to make the Camel walk. Fun and entertaining way to learn how to transform motion.
