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

I'm not sure what You ask, but i will try to guess. Robot that billhowl 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 does not use microcontroller and does exactly what You want it to do - avoids obstacles.

help me
What help exactly do You need?
