Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Be sure to use the Arduino Stack Exchange for questions that are more Arduino and less robotics.

How to check for a sharp angle with a line follower?
The problem seems to be that your robot functions by moving its sensors perpendicular to the line; when the line becomes perpendicular to itself, the robot loses the assumption that lateral movement w …

Arduino original or generic for a beginner?
If you're just starting out, you should probably use the original Arduino instead of a generic.
Let's say you follow an Arduino example using a generic, and things don't work the way you expect. … How will you know whether your Arduino code (or circuit) is the problem, and not the generic board?
In all actuality, a generic board will probably work fine. …

How to make a robot move using Arduino other than timing to predefined locations?
Without sensors or encoders, there is no way to know where you are. Without timing, there is no way to guess how far you may have travelled.
Without sensors, encoders, or timing, it is impossible to …

What is the link between a quadcopter transmitter pulse and the roll/pitch/yaw angles?
The pulse you're talking about is pulse position modulation. Whether this is being used to set the throttle speed of each of your motors (separately), or to convey some other meaning to your flight c …

Using a Bitmap maze image to navigate the maze
It sounds like what you have is an occupancy grid, which you could simply convert to a 2D array of booleans in memory. Your challenge will be to figure out what grid square you are in at any given tim …

Don't understand how sensor works, metal wired directly to I/O pin of arduino
I'm not sure of the exact circuitry that would allow this to work on an the Arduino, but it would be something along the lines of this AC hum touch switch:
Essentially, that the presence of a finger …

Building an open loop controller for a simple DC motor position problem
You would need to construct a model of the motor's performance, and use that model to solve for the input that would give you the output you wanted.
In the simplest case, you could measure the motor' …

Controlling a 400W motor with 24V 16A batteries with an arduino board
$\frac{400\text{ Watts}}{24 \text{Volts}} = 16.666 \text{ Amps}$
So you want something that has an input voltage of 5V (for the arduino to be able to control it), and it should be rated for a 24+ Volt …

Can I make an automatically-parking robot car with IR sensor?
If you use several IR receivers (say, 9 of them) spaced out over a $90^\circ$ arc at regular intervals, you will have constructed a makeshift sensor for detecting the angle of a remote IR emitter. Be …

How to control an Arduino Board with wireless PS3 controler?
I don't have experience connecting a PS3 controller to an Arduino board, but if you can work out a computer-arduino connection then you can use PyGame to read the state of all the buttons and axes. …

How to use scan command in Arduino WifiBee
To my knowledge, the WifiBee doesn't support network scanning. You must specify the SSID of the Wifi network that it should connect to, the IP address it expects to be assigned, and the gateway addre …

Removing quadcopter drift to the side
The drift is being caused either by your position data being consistently wrong, or by your roll/pitch PIDs not correcting the drift error with their integral term.
In any case, it is the integral …
