The Pro-Bot is the 'big brother' of the Bee-Bot and
allows more complex programming involving
•Programmable distances;
•Degrees of turn; and
•Use of sensors.
It includes a simple pen mechanism and a standard
connector texta that can be used to draw routes and
reflect upon and record progress.
The Pro-Bot
•Reinforces concepts across 2D Space sub-strands
•Gives students the opportunity to apply positional
language and extend everyday vocabulary; and
•Encourages small group skills.

draw one side of the square then turn 90º but
do this 4 times.
Rpt[ 4

The number you press is how many times the
action within the brackets is repeated.

after the
key eg 40 (40cm straight ahead)

To change the angle, press 30 (a 30º turn to the left)
Repeat commands for a triangle:
Rpt[ 3 10 120 ]
Repeat commands for a ?
