Qu-Bot, A Quickly Programmable Robot User's Manual
This manual contains crucial information including the precautions that must be taken
seriously to insure trouble free operation of Qu-Bot robot as well as prevent damage
for the users and others. Please read the manual carefully before starting assembly
and programming of Qu-Bot.
Do not disassemble or tamper with any part of the machine.
•
When power is turned on do not touch any conductor such as metal parts
•
to robot. This may damage the robot or some parts of it permanently.
Remove the battery connector when robot is not in use for a long time.
•
Do not store the robot for long time when the battery is discharged. This
•
will drastically decrease the life of battery.
Keep the kit away from small children. There are many small parts which
•
can create problem if swallowed.
Battery and motor connectors are polarized. Do not try to force insert
•
them in wrong direction. This will damage the robot permanently.
Do not dispose the robot or battery in fire. There is a danger of explosion
•
and poisonous fumes.
There are many possible uses of this robot except described in this
•
manual. All these experiments and modifications should be carried out at
owner's risk.
Specifications and product design are subject to change without prior
•
notice. Please refer the latest manual from website www.qu-bot.com.

  • Page 45 Qu-Bot, A Quickly Programmable Robot User’s Manual 8. Application Programs 8.1. Bugler alarm This sample code shows the basic application of sensors and buzzer. • When any of the front sensors senses an object the buzzer goes on for infinite time.
  • Page 46 Qu-Bot, A Quickly Programmable Robot User’s Manual 8.2. Obstacle avoider This sample code shows how Qu-Bot can be programmed to make an obstacle avoider robot. • LCD is initialized to show status of robot. • The robot starts moving when switch 1 is pressed because there is a while conditional loop on top.
  • Page 47 Qu-Bot, A Quickly Programmable Robot User’s Manual 8.3. Edge avoider If the robot is kept on a table surface with this code programmed, the robot moves forward by default whenever it senses edge (Bottom sensors doesn’t sense table surface) it takes actions accordingly.
  • Page 48 This code is made to move robot forward for approximately 1 meter. • The diameter of the Qu-Bot wheel measures 66.3 mm. So the periphery of the wheel becomes 208.182 mm (πD = 66.3 x 3.14 ).
  • Page 49 Qu-Bot, A Quickly Programmable Robot User’s Manual 8.5. Line Follower using one sensor This code uses only one sensor to follow a dark color line on light colored floor. • In the start robot starts running left motor. Right motor is stopped. So the robot takes a long right turn.
  • Page 50 Qu-Bot, A Quickly Programmable Robot User’s Manual 8.6. Line Follower using three sensors This code uses 3 bottom sensors to make Qu-Bot follow a dark color line on light color surface. • When the bottom center sensor is on the dark line the value is 0. This means the robot is on the line.
  • Page 51 Qu-Bot, A Quickly Programmable Robot User’s Manual 8.7. Remote Controlled Qu-Bot Programming this code into Qu-Bot makes it a manual remote controlled robot. • When any switch is pressed on IR remote, it transmits a RC5 code. In the remote included with this kit the code is from 1 to 127.
