I try to run the RedBot Sketch “Drive Forward”, and get an error message that “RedBotMotors” is not a type. I can load the ‘Blink” sketch ok. I see the RedBot folder in the library folder. What is the problem? I am a beginner, and this is very frustrating!! Thanks for any help. ---

Can you post a link to the exact sketch you used, or post the code itself ? My guess is you’re missing a file in the folder (a list of files in or screenshot of the Redbot folder would be nice) or an _#include\<\>_ at the top of the sketch or have a path name wrong. ---

Mee\_n\_Mac; Thanks for the quick reply! Here is the code for the sketch “Drive Forward”. The 2nd line, “RedBotMotors motors;” shows an error…“THIS IS NOT A TYPE.” #include \ // This line “includes” the RedBot library into your sketch. // Provides special objects, methods, and functions for the RedBot. RedBotMotors motors; // Instantiate the motor control object. This only needs // to be done once. void setup() { motors.drive(255); // Turn on Left and right motors at full speed forward. delay(2000); // Waits for 2 seconds motors.stop(); // Stops both motors } void loop() { // Nothing here. We’ll get to this in the next experiment. } Here is a screen shot of the contents of the RedBot folder in the Libraries folder. /Users/21imac/Desktop/RedBotLibraryScreen%20Shot.jpg Here is a Screenshot of the path to the library folder: /Users/21imac/Desktop/PathScreenShot.jpg I hope these images show…my screen just shows the images file names! Thanks! Bruce. ---

Here, I hope, are the images: /Users/21imac/Desktop/RedBotLibraryScreen%20Shot.jpg Path: /Users/21imac/Desktop/PathScreenShot.jpg I’m afraid these are not going to show! Here are the files listed in the RedBot folder in the library: **desktop.ini RedBot\_Experiments RedBot.cpp RedBot.h RedBotAccel.cpp RedBotBumper.cpp RedBotButton.cpp RedBotEncoder.cpp RedBotMotors.cpp RedBotRadio.cpp RedBotSensor.cpp RedBotSoftwareSerial.cpp RedBotSoftwareSerial.h** I see the ‘Bold’ Option does not work. Here is the path to the library: MacHD/Applications/Arduino/Contents/Resources/JAVA/Libraries/RedBot Thanks again; Bruce. ---

We can’t see files on your computer. You can attach images to a post here. Click “Post Reply” \> “Upload Attachment” tab. Click “Browse”, then search for the image. The library should be Documents/Arduino/libraries/RedBot/… (If you’re on a Windows machine.) ---

My path to libraries, on my Mac, is: **MacHD/Applications/Arduino/Contents/Resources/JAVA/Libraries/RedBot** But…I solved the problem with the error message…the code referenced “RedBotMotors”…the correct reference was “RedBotMotor”…NO “S”. So now my sketch compiles ok…but now I get an error “Problem uploading to board”…I’ve tried both USB ports available, and the only 2 Board that references the ATmega 1280 board…I also installed FDLI (?) drivers, as I saw in one post they solved the problem for Yosemite on my Mac. Any suggestions? Thanks…Bruce. ---

I don’t know about your “fix” above. The C++ file is **RedBotMotors.cpp**. I’d have thought the Redbot folder should have been in a Libraries folder directly under the Arduino folder … but I’m on a PC. **\*\*MacHD/Applications/Arduino/Libraries/RedBot\*\*** Note the Mac comments here … [http://arduino.cc/en/Guide/Libraries](http://arduino.cc/en/Guide/Libraries) ---

So I’m stumped…if I add an “s” to RedBotMotor in the sketch it tells me that “it is not a type”. With the “S” it compiles ok, but fails to upload. The detailed error message adds “programmer is not responding”. I’ll delete everything, and download it the software again…tomorrow. I worry that it is a problem with the Yosemite OS…others mention that. Thanks anyway. Bruce. ---

Totally stumped! I deleted everything related to Arduino and RedBot, and downloaded the software and the library again. The ‘Blink’ sketch can be verified and compiled, but will not upload. Error Message: Programmer not responding. I’m worried that it is some incompatibility with the Mac OS 10.10.1 "Yosemite’'. Any suggestions?? ---

My guess is that you have 2 problems; a RedBotMotors path problem and then a driver problem visavis a Mac. I can’t help you on the latter. ---

The Arduino forums will be able to help you with the Mac. ---

I deleted all Arduino things again, downloaded the software and the RedBot Library, installed the Software and Libraries. Then I chose Arduino Uno board, instead of the ATmega 1280, and it works!! I’m not sure what became of the Sketchbook folder during installation, but I simply put the RedBot example scripts in a folder from which I can open them. NOW…I hope to begin to learn the code, as I want to do some projects using light sensors (Photo transistors I think) and also ultrasonic range finding. The electronics and the coding look complex…hoping I can get on to them a step at a time. Valentino Braitenberg wrote a book “Vehicles” which suggests generations of very simple vehicles which display apparent intelligent behavior. I’d like to build a swarm, some acting as predators, some as prey, and maybe build in some apparent learning…there are some good YouTube examples…using Lego Windstorms…see: [https://www.youtube.com/watch?v=G6tlJkRXG3c](https://www.youtube.com/watch?v=G6tlJkRXG3c) and [https://www.youtube.com/watch?v=NJo5HEdq6y0](https://www.youtube.com/watch?v=NJo5HEdq6y0) Bruce.
