ELS 19 – Understanding and communication of directions (EV3)

ELS19 – Understanding and communication of directions (EV3)

Lego Mindstorms EV3 v 1.2.1 for EV3 Firmware version 1.09H

A set of interactions where students follow directions to move a robot, and name directions of movement from their own and the robot’s point of view.

It works in 3 ways:

Part 1: The Student is instructed to verbally or using arrows, move the robots in a particular direction using the remote control or the tablet.

Part 2: The Student is asked to move the robot around a maze and asked to name the direction of movement at various turns in the maze.

Part 3: The Student is asked to move the robot in a particular direction, either from their own point of view or from the robots’ point of view. The robot rewards student activities with appropriate praise or behaviours.

Using the IR sensor and RemoteControl app:

  • Both up buttons forward
  • Both down buttons backwards
  • One up and one down spin on the spot
  • Using the tracks individually causes the robot to move and turn
  • Toggle button at the top of the remote causes the third motor to run moving the head and arms

Using the stepwise EV3 remote app, the robot can perform the following separate programs:

  • Program path: “ELS01p3/MoveForward” – move 1 step forwards
  • Program path: “ELS01p3/MoveBackwards” – move 1 step backwards
  • Program path: “ELS01p3/Turn90R” – turn 90 deg right
  • Program path: “ELS01p3/Turn90L” – turn 90 deg left
  • Program path: “ELS01p3/Turn30R” – turn 30 deg right
  • Program path: “ELS01p3/Turn30L” – turn 30 deg left
  • Program path: “ELS01p3/MoveArc” – move through an arc of 90 degrees.
  • Program path: “ELS01p3/welldone” – Random well done reward sound
  • Program path: “ELS01p3/tryagain” – Random try again sound

These may be called using the Edurob App.
