How to Program Early Years Roamer to Move, Turn and Wait

Programming EYR from Dave Catlin on Vimeo.

Direction, Turning and Angle

Objective

You’ll learn how Roamer’s shape contributes to an understanding of direction, turning and angle.

Playing Turtle

A child plays Turtle when they imagine themselves to be the robot. When they move and turn like the robot they think about what they’ve got to do to make the robot to achieve a task. Playing Turtle makes the Roamer an object to think with and connects students to powerful mathematical ideas.

Direction

The analogy of nose and tail reinforces the idea of direction. You can stress this more by using Transfers making Roamer Characters. When students do this they increase their empathetic bond with the robot.

Turning

Roamer helps children understand angles in two ways:

  1. Turn – The sweeping action of Roamer turning like the hands of a clock.
  2. Shape – The angles shown by Roamer’s pathways.

Forward Instruction

Objective

You’ll learn how to program the Roamer to move forward and backward.

General

Unlike the other Standard Roamers, the Early Years Roamer uses a counting paradigm.

Forward Instruction

http://using.roamer-educational-robot.com/files/2017/02/FD.png Moves the Roamer forward one unit.

Backward Instruction

http://using.roamer-educational-robot.com/files/2017/02/BK.png Moves the Roamer backward one unit.

Example Program

http://using.roamer-educational-robot.com/files/2017/02/FD.png http://using.roamer-educational-robot.com/files/2017/02/FD.png Moves Roamer forward 2 units.
http://using.roamer-educational-robot.com/files/2017/02/BK.png http://using.roamer-educational-robot.com/files/2017/02/BK.png http://using.roamer-educational-robot.com/files/2017/02/BK.png Moves the Roamer backward 3 units.
http://using.roamer-educational-robot.com/files/2017/05/GO.png Roamer moves forward 2 units and backward 3.

Technical Note

The correct technical phrase for moving forward and backward is linear movement. We use the term ‘move’ as a general term to describe the Roamer moving forward or backward. You’ll become familiar with the phrase move and turn, which we use to describe Roamer’s linear and turning movements.  Note: We’re not suggesting you use this term with young children.

Turn Left and Right

Objective

You will learn how to program Roamer to turn left and right.

Left Turn Instruction

http://using.roamer-educational-robot.com/files/2017/02/LT.png Turns the Roamer Left one unit.

Right Turn Instruction

http://using.roamer-educational-robot.com/files/2017/02/RT.png Turns the Roamer Right one unit.

Example

http://using.roamer-educational-robot.com/files/2017/02/LT.png http://using.roamer-educational-robot.com/files/2017/02/LT.png http://using.roamer-educational-robot.com/files/2017/02/LT.png Turns Roamer left 3 units.
http://using.roamer-educational-robot.com/files/2017/02/RT.png http://using.roamer-educational-robot.com/files/2017/02/RT.png Turns Roamer Right 2 units.
http://using.roamer-educational-robot.com/files/2017/05/GO.png Roamer turns left 3 and then right 2 units.

Units of Move and Turn

Objective

You’ll learn about defaults and units of movement and turn.

Default Units

A default is a setting or value automatically assigned to an application. This implies that you can give the unit a different value.

Default Units for Forward and Backward

The default unit for forward and backward is 20 cm. It’s the same length as the Roamer body. We chose this unit to make the robot a yardstick to help students develop their estimation skills.

Default Units of Turning Left or Right

The default unit for turning is quarter turns.

Example

http://using.roamer-educational-robot.com/files/2017/02/FD.png http://using.roamer-educational-robot.com/files/2017/02/FD.png http://using.roamer-educational-robot.com/files/2017/02/FD.png Moves Roamer Forward 3 default units (3 x 20cm = 60cm)
http://using.roamer-educational-robot.com/files/2017/02/LT.png http://using.roamer-educational-robot.com/files/2017/02/LT.png Turns Roamer Left 2 default units (2 x 90 = 180 degrees)
http://using.roamer-educational-robot.com/files/2017/02/BK.png http://using.roamer-educational-robot.com/files/2017/02/BK.png Moves Roamer Backward 2 default units (2 x 20cm = 40cm)
http://using.roamer-educational-robot.com/files/2017/02/RT.png
http://using.roamer-educational-robot.com/files/2017/02/RT.png
http://using.roamer-educational-robot.com/files/2017/02/RT.png
Turns Roamer Right 3 default units (3x 90 = 270 degrees)
http://using.roamer-educational-robot.com/files/2017/05/GO.png Roamer moves Forward 3 units, turns left 2 units, moves backward 2 units and turns right 3 units.

Wait

Objective

You’ll learn how to make Roamer stay still and silent.

Wait Instruction

http://using.roamer-educational-robot.com/files/2017/05/Wait.png Makes Roamer stay still and quiet for one second.

Example

http://using.roamer-educational-robot.com/files/2017/02/FD.png http://using.roamer-educational-robot.com/files/2017/02/FD.png http://using.roamer-educational-robot.com/files/2017/02/FD.png Moves Roamer Forward 3 (3 x 20cm = 60cm).
http://using.roamer-educational-robot.com/files/2017/05/Wait.png http://using.roamer-educational-robot.com/files/2017/05/Wait.png Makes Roamer stay still and silent for 2 seconds.
http://using.roamer-educational-robot.com/files/2017/02/BK.png http://using.roamer-educational-robot.com/files/2017/02/BK.png http://using.roamer-educational-robot.com/files/2017/02/BK.png Moves Roamer Backward for 3 ( 3 x 20cm = 60cm).
http://using.roamer-educational-robot.com/files/2017/05/GO.png Roamer moves Forward 3 units, Waits still and silent for 2 seconds then moves Backward 3 units.
