TOP TIPS TO GRAB AND LIFT!
- Plug the medium motor into Port A and remember to ‘click’ that cable into place.
- Start with a low power level so that you can see the effect – and avoid your mechanism breaking itself off!
- If your mechanism is moving in the wrong direction, change the ‘power’ level to a negative number.
- Your program may need to ‘reverse’ the motor position to place an object that was lifted.
- Add other bricks to the mechanism to make it achieve the precise movement that you want.
- When the motor is ‘stopped’ (if it’s obstructed for instance) from completing the number of degrees, it will not do anything else until it is allowed to complete the specified number of degrees (so when the obstruction is removed).
LET’S DO A REALLY QUICK BUILD…
In this video, Colin shows how to build a mechanism that will get your robot lifting, dragging or even throwing! Using the ‘two funky black gears’ and a few other bricks, you’ll be up and scooping in no time at all! This will be really useful for lots of the tasks that require lifting and grabbing!
LET’S GET PROGRAMMING…
Programming the medium motor is simple but you will need to try out different values to get the desired result. In this video, John also demonstrates using a Loop block.
YOU CAN USE THIS MECHANISM ON THE CRANE MISSION (MISSION 2)
AND FIRST LEGO LEAGUE HAVE ALSO GIVEN YOU A SOLUTION TO THIS MISSION!!!
We think that your robot and program will be brilliant! This year, to help you, FIRST LEGO League have also provided a build for a robot and a program to solve the The Crane Mission (Mission 2). Always good to have some help 🙂 Maybe your model and program will be even better 🙂
Have a look at the extra help:
How the LEGO Tutorials in your software can help you in your Missions, and a particular focus on The Crane Mission (Mission 2)
GREAT SUPPORT FROM LEGO EDUCATION
- From the Lobby (the starting page) go to ROBOT EDUCATOR and choose BASICS and MOVE OBJECT. The lesson gives instructions for building the standard robot, adding a dragging mechanism and programming them.
- Go to the ROBOT EDUCATOR TUTORIALS by clicking on the arrow on the right side of the home page (The Lobby). Select MOVE OBJECT to see the same lesson there.
