How to create random movement

How to create random movement for a bot? (top down)

with random, people hardly ever mean random..

would the movement distance be limited?

would the angle of movement be limited?

would the speed be limited?

should the movement react to the environment?

"random" movement can be made with any of the build in behaviours..

With better explanation better solutions can be provided..

No limited distance, no angle limitation, limited speed and the movement should react to any solid objects

so something like every x seconds set direction of movement should work?

with 8 direction this would be setting a variable and simulate pressing directions

with bullet it would be set angle to random(360)

Yeah it worked perfectly, thanks.
