Robotics with LEGO - Level 2.5 - Maritime Journey

The fourth level of the Robotics with LEGO curriculum for students from fifth to twelfth grades.

In this level students focus on the rotational sensor that is part of every motor in the robotics set. Students also learn to use the fourth sensor in the robotics set - the gyro sensor.
First few robot constructions imitate sea-animals and their behavior. Students create programs that check whether the robot's claws or pecks have successfully caught an object. That sensor in the motors allows the robots to go back in their lairs even after the use of unlimited movement. The rest of the robots are modeled after boats, yachts, and ships. With the help of the gyro sensor, students can set a course for their robots to a given angle and can detect deviations from the course. In open seas, there may be sea-monsters and the robots are being programmed to detect a sudden change in acceleration with the help of the said sensor.

Spy Vehicle - LEGO Mindstorms EV3 Vehicle acting as a spy

Following the Spy Bot, we have this new Spy Vehicle. Yes, yes it is using an ultrasonic sensor.

The building instructions are for a robot base that looks like a car but is not exactly a car and has a strange shape. Just like spy vehicles - a car, but not only a car and not just a car.

Simple Pinless Attachment for the SUV Box Robot

This is a simple pinless active attachment for the SUV Box Robot.

In this attachment we use "(32498) Technic Gear 36 Tooth Double Bevel". There are four pins added to the wheel and it it this pins that engage with the "(32072 ) Technic Gear 4 Knob". The more important thing is that the knob wheel and the gear wheel are parallel to each other.

While the motor rotates the attachment has 4 points of contact (instead of one or two when two Knob Wheels are in contact) with the robot knob wheel. There are no forces that drive the attachment to jump and lose engagement with the robot.

Commands with multiple input parameters

So far, you have used commands requiring only one input parameter, but many commands in programming require a lot more than one type of information. Such an example is the "run_time()" command.
