So, did you say robot?

Yes, they are robots but…

…this is a robot too

Its name is “ALDO”

Motor#1

Motor#2

Caster

Wheel

ALDO can :• Move forward• Move backward• Turn left• Turn right

Platform

But how to control ALDO?

With a remote control…

…with wires connected to the motors

And how to build the remote?

It might look like that…

But the design (and wiring) is up to you, to make the robot move

Microswitch

Push Button

Connector toRobot

Mutiple wirescable

Power supplyconnector

And…that’s all??Well, it’s a minimum!

But the secret ingredients for success are:

Imagination Motivation

Where to start from?

From Afrobot 2012’s rules

• Feel the spirit of the competition

• Understand the strategy to adopt

• Design your robot accordingly

What material do I need?For a basic robot…

…this is a minimum

Qty Description

2Geared motor, DC, 6V…12V, ~ 0.5 Amp between 200 and 300 rpm

2 Wheel – that fits in the shaft of the geared motor

1 Wheel caster or ball caster – large or small

110-wires cable (or set of 10 wires/ ribbon cable) about 3 to 4 meters long

1Set of Male+Female connectors for the wires (DB9 works well – crimp type requires no soldering with ribbon cable)

ALDO: a typical list of material (1/2)
