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
Garage Parking Helper With Arduino
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!
Accident Alert System Using GSM, GPS and Accelerometer
Cool!, have you ever used an arduino Yun with blink? Is it the same process?
Neat, this could even be solar powered!

Amazing 3D Projection Pyramid in 10 Min From Clear Plastic Sheet !

WALTER (Arduino Contest)
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!

Welcome to Arduino
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
