Educational Robot for Under $100

While schools have been using robots to educate students in the art of science and engineering for decades now, not every school or teacher can afford to put one of these robots in the hands of their students. For that reason, it’s important to not only improve the robots themselves, but to help drive the costs down to make them more accessible. The CodiBot does this well, and comes in with a price tag well under $100.

The robot itself comes pre-assembled, and while it might seem like students would miss out on actually building the robot, the goal of the robot is to teach coding skills primarily. Some things do need to be connected though, such as the Arduino and other wires, but from there its easy to program the robot to do any number of tasks such as obstacle avoidance and maze navigation. The robot can be programmed using drag-and-drop block programming (similar to Scratch) but can also be programmed the same way any other Arduino can be.

With such a high feature count and low price tag, this might be the key to getting more students exposed to programming in a more exciting and accessible way than is currently available. Of course, if you have a little bit more cash lying around your school, there are some other options available to you as well.

QP-Nano QM State Machine Programming?

Hello,

Has anyone worked with qp / qm state machine programing?

http://www.state-machine.com/

I am looking into this for controlling robots.  Has anyone here used it or has any opinion about it for programming Arduino ?

Thanks

Arduino code - switch statement

Hi, I code a program for my autonomous robot. I am sending numbers from 0 to 8 from Raspberry pi to Arduino through Serial communication. I have Rasp code. But arduino code has some problems. Please can you tell me how to write it best? I want to use switch statement to choose direction for my robot/motors. But when I compile that code to arduino on robot - my robot start doing only default commands. Please why????

Raspberry pi and Arduino serial communication

Hi, I have a problem with serial communication between Rasp and Arduino. I have written code for both. When I try serial communication on Rasp in Arduino IDE it is working. But when I try serial communication by code on Rasp, it is printing rectangles (in arduino serial monitor) and no what I send from rasp to arduino. So can anyone help me? :)

here is link to photo of arduino serial output https://www.dropbox.com/s/vjvd4p76mmu4ciq/rectangles.png?dl=0

Ultrasonic Collision Avoidance Arduino and Raspberry Pi

Hi;

I am building and testing a telepresence wheeled rover bot that has two methods of control:

1. Web Interface (Manual Mode): This consists of a control panel on a web page served using WebIOPi on a Raspberry Pi which, when activated, sends commands to an Arduino Nano AT Mega328P via a two wire i2c interface (Forward, Back etc).
