What is an actuator????

a device carrying out physically the commands by cpu like an arm

What is an actuator????

its a robotic arm used in factories and sometimes in making cars

No need to use them dude. you can write them in simple.

like

PENDOWN
LEFT 90
FORWARD 20
LEFT 90
FORWARD 20
RIGHT 90
FORWARD 10
PENUP
FORWARD 20


can also be written as

PENDOWN
REPEAT 2
LEFT 90
FORWARD 20
ENDREPEAT
RIGHT 90
FORWARD 10
PENUP
FORWARD 20

But hey wouldn't be change the direction after Forward 20? Like degree to turn it or something?

 

[syed1995]

is it necessary to use loops in floor turtlr

No If it comes in paper i won't use the loop at all!

but that question required to use it as the line repeat was already given.

I wasn't referring to your question, if that's what you mean .. i was just giving a rough example dude.

Ohhh! I hope this doesn't come.

Does forward 20 mean its moved forward twice?

 

[syed1995]

the question one's answer is


PENDOWN
LEFT 90
REPEAT 3
FORWARD 30
RIGHT 90
ENDREPEAT
FORWARD 10
LEFT 90
PENUP
FORWARD 10
PENDOWN
FORWARD 20
{RIGHT 90
FORWARD 20
RIGHT 90
FORWARD 20}
LEFT 90

the above in brackets could also be.

REPEAT 2
RIGHT 90
FORWARD 20
ENDREPEAT

 

[syed1995]

Does forward 20 mean its moved forward twice?

Depends on what the scale is given.

the scale for this question was each box represents 10 units. so if the turtle moved 2 boxes forward it meant forward 20.

"(Each square in the drawing below is 10 cm by 10 cm.) "

 

[SalmanPakRocks]

Hey how do we calculate the scale?

 

[bogus]

left right thing is the angle like left 90 is 9o degree anticlockwise

oohhh, thanks

Ohh I get it. Thanks.

 

[syed1995]

Ohh I get it. Thanks.

I'll be in an hour or so, gonna solve some past papers.

What is an actuator????

an actuator is a mechanical device that converts energgy into motion.....

 

[syed1995]

an actuator is a mechanical device that converts energgy into motion.....

is it in our computer syllabus ??

 

[moiz 95]

nope.

 

[syed1995]

Ohhh! I hope this doesn't come.

You can practice commands over here..

just remember that in here REPEAT LOOP goes like REPEAT [ COMMAND ]

 

[moiz 95]

guys i have got a guess it says.......

*CAD(FEATURES)
*Virtual (how to crete images for use on comp)
*sensors
* xpert system(medical/ mechanical)
* algorithm on database update...
* intranet
*hand shakking/ interrupt............
