Abstract: In this paper we deal with using Lego Mindstorms in
simulation of robotic systems with respect to cost reduction. Lego
Mindstorms kit contains broad variety of hardware components
which are required to simulate, program and test the robotics systems
in practice. Algorithm programming went in development
environment supplied together with Lego kit as in programming
language C# as well. Algorithm following the line, which we dealt
with in this paper, uses theoretical findings from area of controlling
circuits. PID controller has been chosen as controlling circuit whose
individual components were experimentally adjusted for optimal
motion of robot tracking the line. Data which are determined to
process by algorithm are collected by sensors which scan the
interface between black and white surfaces followed by robot. Based
on discovered facts Lego Mindstorms can be considered for low-cost
and capable kit to simulate real robotics systems.
Abstract: This project focuses on the development of a line
follower algorithm for a Two Wheels Balancing Robot. In this
project, ATMEGA32 is chosen as the brain board controller to react
towards the data received from Balance Processor Chip on the
balance board to monitor the changes of the environment through
two infra-red distance sensor to solve the inclination angle problem.
Hence, the system will immediately restore to the set point (balance
position) through the implementation of internal PID algorithms at
the balance board. Application of infra-red light sensors with the PID
control is vital, in order to develop a smooth line follower robot. As a
result of combination between line follower program and internal self
balancing algorithms, we are able to develop a dynamically
stabilized balancing robot with line follower function.
