Varasto - a LEGO Mindstorms EV3 warehouse robot
Varasto from Finnish means warehouse.
This is a simple warehouse robot made to hold and drag objects. It uses two Large motors to move around and one medium motor for a grabber. The grabber is at the front of the robot and consists of two double angular lift-arms that are each connected to a gear, which allows them to function like a grabber.

Implementing a "WaitForTick" logic in your EV3-G program
Sometimes when we are working with sensors it is important that the time between two consecutive samples is the same. This will make each sample equally important and independent of how much time it took to take it. In this video tutorial, we would use the EV3-G timer block to make a "WaitForTick" program where the time between each sample of the EV3 Gyro takes exactly 0.02 seconds.

Move tank block in Mindstorms EV3-G software.
There is the Move Tank programming block in the software. It allows us to set different power to each motor.
In real life, the same concept is used in cars, for example. The traction control systems apply different power to different wheels, so that the car is more stable on the road during turns or on slippery road.
