If the Arduino code fails to compile in the Arduino IDE, save the file, close the program and reopen the file from its file location in its folder. If the program fails to upload, make sure that you are using a data transferring usb cable rather than just a power one. Unplug and plug in again and make sure that both the computer and Arduino have a secure connection to the cable.

Issue Resolved: See Step 7 for code.

The program may crash if the ultrasonic power pin turns off, therefore I have commented out those lines of code that turn off the ultrasonic sensor.

Neat, but how do you ensure security on such a device? Well written instructable!

Nice, If I make one in the future, I'll definitely click the I Made It! button!

Neat,it looks like it took a lot of work to write this instructable; ever considered making a facial recognition safe? I wonder where you'd start

Nice instructable! Can you use bluetooth to communicate with other arduinos? If so where would I start?

Neat!, I'd also recommend looking into a PIR motion sensor

So Cool!, check out the parking helper I made! Is there a video of it working? Nice Job!

Is a cellular connection needed for this? How is the data sent? Nice project!

Cool!, have you ever used an arduino Yun with blink? Is it the same process?

Thanks!

Neat, this could even be solar powered!

How does the robot sense edges? Does the ultrasonic sensor see if there's a corner? Cool robot! My instructable also uses ultrasonic sensors, but to detect cars!

haha, I know right but not if the sensor has anything to do with it:)

This looks really cool. I imagine that you could also design a battery tray, print that and attach it to your bike. Do you know if there's a standard wheel size for bikes such that this model could work on other bikes? Thanks!

Can it go on water? That would be great to see as an update.

I saw it, it looks really great!

Will do; Thanks for the suggestion! I know that your suggestion would help especially for stabilization. Thus far, I've used gimbaled thrust and thrust vanes to control the craft, but not movable fins as you suggest!Here's a linkhttps://spaceflightsystems.grc.nasa.gov/education/rocket/rktcontrl.html
