[SOLVED] Strange compilation error

Hi everybody!

I'm making a little robot using Arduino and it works fine (you can see how it works on the embedded video).

The robot walk alone perfectly but today I tried to use an infrared remote with an infrared receptor to use my robot like an RC car, and I had this error at compilation (I'm using IRremote library):

WhiteBOB - preview

This is WhiteBOB, my member of the BOB family. Because I have no access to a 3D-printer this robot is build from polystyrene sheets (3 and 1mm) and a piece of PVC corner strip.

Arduino Robot Review

Here at Banana Robotics, we're very lucky to have a sneak peak at the Arduino Robot. It's about 7 inches in diameter and features two separate Arduino microcontroller boards. The upper deck is the Control Board and the lower deck is the Motor Board. Each board has TinkerKit type connectors for expansion. The two boards talk to each other via a serial port.

Just a quick question regarding battery use on a hack RC car.

Would it be a bad idea to power my robot with one battery. I would be using 5 rechargerable batteries which will give me 6-7volts or should I just power my atmega328 and maybe ultrasonic ping sensor with a 9volt batteries and the rest with the rechargerable.

Standalone atmega328

1 dc motor with L293D

1 micro servo

1 ultrasonic ping sensor

6 leds (3 sets each)

Issue with L293D

For some reason I can't get my H-bridge to turn my motor both direction. It was working a week ago when I was working on it. When I turn Input 1 High and Input 2 low it will turn the motor forward but when I turn Input 1 Low and Input 2 High and doesn't do anything. Well actually I can feel like a buzzing sound like its trying to work. I am powering the H-Bridge with it own power supply on pin 8 (Vs). Maybe something I'm missing.  I will tried adding some capacitor in to see if that help any.

Using Sabertooth 2x12 with motor and servo.

 

I have an RC car that i've stripped down to it's bare essentials.  It has one motor that provides forward/backward movement and it has a servo that turns the front wheels left/right.   I can use the Sabertooth 2x12 fine with the motor.  The problem is however the servo.

Doodle bot not connecting

I recently purchased the DAGU kit for the Doodle bot. I set it all up as per the instructions and uploaded the sample text. I am a beginner and was hoping to use this simple kit to learn the basics of how all the components work and are programmed. Originally I was unable to get the robot to work properly, the right motor would spin continuously and the left was not responding (I checked, both motors were fine though).

 

However, now I am unable to upload the sketch to the controller. I get the following error:
