ServoBot LED Headlight & Sharp IR Bumper

In this post I will demonstrate the assembly of the bumper for my current robot build Ratchet. The bumper contains both a Sharp IR distance sensor (for obstacle avoidance) and a pair of LED's for headlights. One of the key features that I liked about my last robot build Sheldon was the use of flashing combinations of the headlights to indicate information such as current mode etc. I found it so useful that I decided to duplicate this functionality for Ratchet too. ...more

Arduino and the Sharp IR Proximity Sensor

In my last post I demonstrated how I modified a couple of Sharp IR sensors for use with my ServoBot Shield. It recently dawned on me however, that some of you might not know what these sensors are for, and how they are used. With that in mind I decided to put together this quick post as a bit of an introduction etc. Introducing the Sharp IR Sensor The Sharp IR family of proximity sensors are probably the most commonly used sensors by robot hobbyists. This is because they are inexpensive and are ideally suited to small robots. ...more

Sharp IR Servo Plug Tip

This post is really a tip rather than a tutorial. Within it I will demonstrate how I prepare sensors and components such as Sharp IR's to be compatible with the ServoBot Shield. Essentially all that's really going on here is the fitting of servo plugs so that whatever component can easily be plugged into the shield, and then removed again if necessary. I think that this is a really useful way of being able to connect sensors so that they can be changed  as I see fit whilst also ensuring that the connections are secure. ...more
