LEGO Education SPIKE Prime

In this video tutorial we deliver the Innovation project model from base to the cargo connect marker on the field. The goal of the mission is to deliver. The mission model is assembled before that.

This is a 10 out of 10 tutorial on an active, auto-correcting, locking, and aligning attachment that accomplishes the FIRST LEGO League 2021-2022 Cargo Connect Large Delivery mission. The difference, as compared to the previous solution to the mission, is that we now use a much more consistent and reliable robot.

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())
