Lego Motions — Tribot v 1.0

Seeing Your Creation Move — Move Steering Block — Episode #04

Seeing your creation move is one of the most exciting and fascinating things about making a robot. videos? click here now!

Tribot base constructions instructions

In this Episode, we’re gonna explore the setup of Large Motor from EV3 31313 :)

The EV3 Large Servo Motor is a powerful motor that uses tacho feedback for precise control to within one degree of accuracy. By using the built-in rotation sensor, the intelligent motor can be made to align with other motors on the robot so that it can drive in a straight line at the same speed.

It can also be used to give an accurate reading for experiments. The motor case design also makes it easy to assemble gear trains.


Description Ev3 Large Motor:
– Tacho feedback to one degree of accuracy;
- Precise movement;
160–170 PEAK RPM;
Running torque of 20 N/cm (approximately 30 oz/in);
Stall torque of 40 N/cm (approximately 60 oz/in);
– Auto-ID is built into the EV3 software;
- It has an unusual shape;
- Inside it is a set of gears, electric controller circuit (build-in rotation sensor);
- Weight = 82g

Steering Blocks

The settings you choose will depend on how you construct the Robot and what you want it to do.


Off -> Turn off the motor;
-> Stay on until prog ends or tunned off by another block;
On For Rotation -> Move the motor determined number of turns;
On For Degrees -> Moves the motor determined number of degrees;
On For Seconds -> Move the motor determined number of seconds.


            Slider to the middle the robot move straight


Positive value move the motor forward; negative, backward;
Applying 100 the motor runs it as fast as it can :)


In order to know how much a spin is worth, solve for circumference or see this video =D

Brake At End

Port B = Left Motor

Port C = Right Motor

Port View

- Port View is a Big help :D it says how far each motor has moved;
- You can move motor by hand to determine the distance you want it to go;
- Values are reset to zero at the start;
- You can add Wait Block to make the program pause if you want to check the value at various steps.

Please see this video for my laboratory about the Move Steering Block:

That’s all for now, folks.

See you soon!
