Mindstorms NXT dual-ultrasonic object follower

[LoneWolf783]

How do you program it to run straight in till (as in actually interuping the curent task (of driving straight,)) it gets to a wall and then turn? Also, can you use it like a motion sensor?

[TheNeXTStorm]

can you send me the program

[uhjohn]

@TheNeXTStorm @NXTFreak maybe put it up under video?

[Rakaloe]

can you do it with one ultrasonic sensor too?

[Zyeiketopia1018]

then put a camera on it and- presto, it's a security cam!

[DronElektron]

Thats cool but easy to programm... you can make tham to follow to object))) :D

[kayserikay]

How does it compare the values of the two sensors? Does it turn towards the largest value like my sound sensor face or what?

idk if u know how but i've been messing w/ my programming.....how do u get ur robot to back up if its too close or a wall or object like it??

[NXTFreak]

Well, it sounds like you want a switch block in your program. You can set the switch block to use the ultrasonic sensor, and then set the parameters to how close/far away the object will be. Put whatever blocks you want to execute if the parameters are true in the upper sequence beam of the switch block, and whatever blocks you want to execute if the parameters are false in the lower sequence beam. Hope that helps. NXTFreak

So it rotates just fine.... can it follow an object forward and backward?

[NXTFreak]

No, it can't. It can only go left and right.

[BoffinbraiN]

Great! I definitely want two sonars now.

[DamianProgrammer]

yup
