INTRODUCTION

The Programmable Robot has a control system (called

the IQ4 controller) which is easily programmed to

control a left and a right motor. When both motors are

on the robot moves forward (or backward). When just

one of the motors is on the robot turns left or right. If

the two motors run in opposing directions the robot will

spin on the spot.

BUILDING YOUR ROBOT

1. Using a screwdriver and a pair of pliers, ﬁt the

castor wheel onto the metal bracket. Use the pliers

to hold the nut while carefully tightening the screw.

Don’t over-tighten the screw - the wheel should be

free to turn.

2. Insert the long screw (M4 x 40) through the metal

bracket and thread a nut onto the screw as shown.

Do not tighten the nut - the bracket should be free

to turn on the screw.

3. Insert the castor wheel screw through

a hole in one of the chassis plates.

Thread a nut onto the screw and

tighten it.

Insert the two M4 x 30 screws through

the other two holes in the chassis

plate. Slide the guideplate over the

screws then tighten a nut onto each

screw.

4. Attach a sticky pad to each of the

motors. Stick the motors onto

the chassis plate as shown using

the guideplate to ensure correct

positioning.

5. Twist another nut on to the end of

each screw so that approximately 7mm

of thread is exposed on the shorter

screws and 12mm of thread is exposed

on the longer screw.

6. Fit the second plate over the screws

and secure it using three nuts.

7. Make sure the switch on the battery

box is ‘OFF’, then insert 3 x AA

batteries into the battery box. Take

care to ensure the batteries are

inserted the correct way round.

8. Using one of the sticky pads, stick the

battery box to the top plate in the

position shown.

9. Use another sticky pad to stick the IQ4

controller on top of the battery box.

Cut the connector off the end of the

wires from the IQ4 controller.

10. Use the ﬁnal sticky pad to ﬁx the

connecting block to the top plate as

shown. Carefully strip the ends of the

wires from the IQ4 to expose the metal

wire strands.

Join the wires from the battery box

to the wires from the IQ4 using the

connecting block. (Loosen the screws in

the connecting block before inserting

the wires, then tighten the screws to

hold the wires in place).

11. Carefully strip the ends of the wires

from the motors to expose the metal

wire strands.

Insert these wires into the connecting

block on the IQ4 controller. The red

and black wires from the left motor

should connect into the left side of the

connecting block. Ensure the wires

are connected in this order: red, black,

black red.

12. Place one of the small washers into the

centre of one of the wheels, then press

in one of the plastic wheel inserts.

Repeat with the second wheel.

13. Carefully press the wheels onto the

motorised gearboxes then ﬁx them in

place using the remaining screws and

washers. A gentle force will be needed

to ensure the screws bite into the

plastic.

Your robot is now ready to use.

PROGRAMMING YOUR ROBOT

The IQ4 controller can be programmed to switch the two motors forward, reverse or off in a desired sequence.

Programming is achieved using the two ‘output’ switches, the ‘reverse’ switch and the ‘save’ switch. The ‘run’

switch is used to start or stop a program.

The IQ4 board will ‘remember’ a sequence of up to 60 switching steps. At each step either of the outputs can

be switched forward, reverse or off. The overall time delay between each step can be adjusted by pressing the

‘reduce run speed’ or ‘increase run speed’ switches while a program is running.

Switch the power ‘ON’, then try this example program:

1. Press the output [1] switch and the output [2] switch so that the green lights appear above the switches.

(The motors will start turning forward.)

2. Press the ‘save’ switch once. (The red light under the ‘run’ switch will ﬂash twice to show the save

switch has been pressed.)

3. Press the output [2] switch so that the green light above it turns off. (The right hand motor will stop

turning).

4. Press the ‘save’ switch once.

5. Press output [1] switch so that the green light above it turns off. Press the output [2] switch so that the

green light above it turns on. (The left hand motor will stop turning and the right hand motor will start

turning).

6. Press the ‘run’ switch once and put the robot down on a ﬂat surface.

The robot will repeat the following movements: forward, turn left, turn right.

The program may be summarised in the following table:

Note: while the program is running the time between each step of the program can be increased or decreased

by pressing the ‘increase run speed’ or ‘reduce run speed’ switches.

ADDING STEPS TO A PROGRAM

1. Press the ‘run’ switch so that the light under it turns red and the motors stop turning.

2. While both of the outputs are off press the ‘save’ switch once. This will cause the robot to stop for a

moment when the program is running.

3. While holding down the ‘reverse’ switch, press the output [1] switch and the output [2] switch so that

the red lights appear above the switches. Both motors will start turning backward.

4. Press the ‘save’ switch twice. This means the robot will reverse for two steps of the program.

5. Press the two output switches once so that both outputs are off, then press the ‘save’ switch once.

6. Press the ‘run’ switch once and put the robot down on a ﬂat surface.

The robot will repeat the original program but after turning right it will then stop for a moment, reverse and

then stop again.

ERASING A PROGRAM

The IQ4 controller will ‘remember’ a program even when the power is switched off. To erase a program hold

the ‘run’ switch down for 3 seconds until the light ﬂashes.
