I'm sorry for ANOTHER stupid question, but I'm having a REEEALLY hard time following the Tutorials and searching for help in the forums here. I've just attached my ultrasonic distance sensor to my EZ-B4, but I can't figure out how to do anything with it. At this point, I just want to have my robot navigate autonomously (which, to the best of my knowledge, should be a fairly simply process) before moving on to more complex tasks, but I've got no idea how to proceed from here. What do I need to do to figure this out?

I slowed down the robot's speed, and it encountered the same issues as before. Sometimes it detected objects and avoided them, sometimes it didn't. I tried hitting STOP on the movement control and it just kept on going.
the dots below is what the robot detects.
I'm sorry for ranting, but every problem I'm encountering with this is just REALLY frustrating, compounded by how it appears that I'm the only one having these issues.
so rechargebles are not so good for using robots .
a servo is 7.4 volt .the batterie case has 6 x 1.2 volt=7.2 volts not enought.
what happens when you slow down the speed even more?
learn to be patients .you will live longer.:)

we’re not ezrobot. Ezrobot won’t see your messages or product feedback here.
as for using an ultrasonic distance sensor, there’s some info in the ARC manual in the docs section
witsh ARC are you using?
Here are my current ultrasonic settings, and the only values here that I recognize are the EZB ports into which I've plugged the appropriate servos and ultrasonic sensor.
What's weird is that I didn't even need to hit the FORWARD command on the servo Movement Panel like I was doing before. As soon as I connected the robot, it was moving on its own. But it wasn't even MOVING on its own, it was... rocking to the left and right very faintly, and backing up slightly. Yes, I see that I have 'Reverse Before Turn' selected, I wanted to give it some room to clear whatever might be blocking its way. But now it's just looking back and forth slightly, not going anywhere, but backing away, and then it just STOPS before I tell it to stop. Hitting the Stop button myself doesn't work, and if the radar scan screen devoid of red dots is any indication, it wasn't detecting anything.
It seriously looked like it was AFRAID of doing anything, and it couldn't even see any reason TO be afraid of doing anything. :/
you can delete the camera window if you dont use a camera.
what kind of wheels are you using?
does your arrow keys work fine now?
do you save your project on your pc?and maybe you can take a new window ultrasonic.
check the cabke from your camera bolt sides.
And as near as I can tell, the connection of the cable on both ends of my camera is perfectly fine.
also i read some post about the camera cable.solution is to turn the cable 180 degree.
And I guess I'll poke around what the other tutorials have to say about the ultrasonic sensor.
to turn left/right its more fun.
