Robotics
Robotics is a branch of engineering
which deals with study of Robots, Its
construction, Operations and Design
etc.

Presented by Rajesh

 A "Robot" is any automatically
operated machine that replaces human
effort, though it may not resemble
human beings in appearance or
perform functions in a humanlike
manner

Three Laws Must be
followed by
THE ROBOT
Presented by Rajesh
Kumar/14001003908 2717:37

Three Laws of Robot
 A robot may not injure a human being or, through
inaction, allow a human being to come to harm.
 A robot must obey any orders given to it by
human beings, except where such orders would
conflict with the First Law.
 A robot must protect its own existence as long as
such protection does not conflict with the First or
Second Law.

How Robot Moves?
17:37
Presented by Rajesh
Kumar/14001003908 30

Description of Movement of Robot
 At first TIMER has to initialize. (AT mega has 3
timers 0, 1, 2).
 OCRX= (int. value 0-255);
 forward movement: 1 in clockwise other in anti-
clock direction.
 Backward: opposite of forward.
 turning left: left wheel having less value of OCRX.
 Turning right: right wheel having less value OCRX.

I/O Function Registers
 DDRX ‐‐‐‐> Sets whether a port is Input or Output
of PORTX.
 PORTX ‐‐‐> Sets the Output Value of PORTX. For
example: PORTA=255 ( all pins work of port A as
output) for LED & LCD.
 PINX ‐‐‐‐‐> Reads the Value of PORTX for ex.
PINA.0=0 (0th pin of port A working as input ) for
switches

Functions in LCD Interfacing
 lcd_clear()  clears screen
 lcd_gotoxy(x,y)  position
 lcd_putchar(char c)  display single character.
 lcd_putsf(string) whole string
 lcd_puts(char arr)  for array
 itoa(int val, char arr[])
 ftoa(float val, char decimal_places, char arr[])
