LEGO Education SPIKE Prime

This is a 10 out of 10 tutorial for pushing gently on a mission model. We also discuss how to build robots that tolerate error and auto-correct their behavior.

This tutorial demonstrates how we accomplish 5 missions in a row with a single robot and three attachments. This is a true multiple missions run for the FIRST LEGO League 2022-2023 SUPER POWERED. We Drop parts, we pull from the Smart grid, we push a lever, we collect a few energy units and we deliver the dinosaur toy.

There is the classic robotics task - maze solving, or navigation in a labyrinth.
Today we will start with an introductory challenge - navigation in a known tunnel.

Did you know you can use the motors as sensors? Here's how!

Solutions to today’s tasks:

Program the robot to lift its arm by 90 degrees in 1 second.

from hub import port
import runloop
import motor, time

async def main():
    # write your code here
    # Start motor
    motor.run(port.D, 90)
    # Wait for 2 seconds
    time.sleep_ms(1000)
    # Stop motor
    motor.stop(port.D)

runloop.run(main())

Program the robot to lift its arm by 90 degrees in 2 seconds.

from hub import port
import runloop
import motor, time

async def main():
    # write your code here
    # Start motor
    motor.run(port.D, 45)
    # Wait for 2 seconds
    time.sleep_ms(2000)
    # Stop motor
    motor.stop(port.D)

runloop.run(main())

Program your robot to hand you its cup using the "run_for_time()" command.

from hub import port
import runloop
import motor

async def main():
    # write your code here
    await motor.run_for_time(port.D, 2000, 45)

runloop.run(main())

Use everything you have learned so far to program the robot to move toward you and then lift the cup.

from hub import port
import time
import runloop
import motor

async def main():
    # write your code here
    motor.run(port.A, 1000)
    motor.run(port.B, -1000)
    time.sleep_ms(2000)
    motor.stop(port.A)
    motor.stop(port.B)
    await motor.run_for_time(port.D, 1000, 90)

runloop.run(main())
