build a simple robot does not use microcontrollers. mainly used transistor. help me

Have you find this...
Line follower, obstacle avoider, photovore and photophobe in $40

If you do not want to use L293D motor driver, you can replace it with transistors H-bridge like this

no microcontroller use L293D. single transistor used. you can make H-bridge controller is smooth ,but how do other

no microcontroller use L293D
I'm not sure what You ask, but i will try to guess. Robot that billhowl (http://www.societyofrobots.com/robotforum/index.php?topic=15152.msg109773#msg109773) linked You to does not use microcontroller. L293D is not uC - it is a motor driver, you either use that or use H-bridge consisting of at least 4 transistors.
single transistor used.
That won't happen ;D
you can make H-bridge controller is smooth
Smooth H-bridge driving (or have You meant smooth motor control) requires PWM which in turn requires uC or something like 555 Timer in astable mode and a lot (and I mean A LOT) of hand tuning.
,but how do other
Sorry, do what now? ;D
NOTE 1: You did not tell us what do You want Your robot to do.
NOTE 2: You would get more replies if Your sentences were constructed better (with more effort say).

I want to make a simple robot automatically. function to the left, right, up and down. avoid obstacles. using transistor. important not to use microcontrollers. help me :'(

Makes much more sense now ;)
I'll repeat myself: Robot that billhowl linked You to (http://www.societyofrobots.com/member_tutorials/node/59) does not use microcontroller and does exactly what You want it to do - avoids obstacles.
help me
What help exactly do You need?
