HomeMade IR Sensor Controlling Robot...Proof of Concept

Primary image

What does it do?

Navigates with IR Sensors

I saw a tutorial that Ro-Bot-X did on controlling a robot with homemade IR Sensors so i decided to try it.  I am using two 38KHz IR Reveivers from RadioShack and two IR LEDs from Radio Shack.

Simple Simon

Primary image

What does it do?

Obstacle avoidance, education

I built this super basic robot as a start-here style bot for a presentation I'm doing in a few weeks. I wanted something I could demonstrate building in realtime to a group of boyscouts. Simon is built with an arduino, dfrobot protoshield, breadboard, 2 parallax continuous rotation servos, 2 solarbotics wheels, a caster and a digital ir sensor. The whole thing is built with double sided tape (fritz start-here bot style). I should be able to demonstrate assembling him and uploading his program in about 15 minutes during my presentation.

Arduino RC Car

Primary image

What does it do?

Drives and avoids obstacles

I had bought a RC Car from walmart for about $15 to use with the Arduino Motorshield a while back (see here). Fortunately, I had taken some pictures before I removed the RC receiver circuit from it. Turns out that its lot more efficient to use the onboard controller along with an Arduino instead of using a motorshield. I didnt some research and found out that many “cheap” RC cars use the same Realtek TX2 & RX2 chips inside. I was lucky enough to find the same inside this RC car.
