If you are willing to accept a few limitations, there are expansion options that can provide both convenience and power beyond what standard Arduino shields offer.

A Robot Operating System On a Chip
September 2012
Building a robot from scratch can be a daunting task for both beginning and advanced hobbyists. The newly available RobotBASIC ROS on a Chip makes the whole process easier and faster by providing a physical interface from simulations to the real deal.

Virtual Sensors — Part 2
August 2012
Last time, we looked at how virtual sensor techniques work. This time, we do the same for virtual motor interfaces.

Virtual Sensors — Part 1
July 2012
In order for your robot to perform properly, it needs as much sensory data as possible. Unfortunately, physically increasing the number of sensors on your bot has potential problems. So, go virtual before completing your design.

Experimenting With Unconventional Wheels

A More Versatile Robotic Controller Using RobotBASIC
March 2008
Today’s hobbyists can purchase robotic platforms with a wide variety of electronic sensors, mechanical actuators, and programmable microcontrollers. This means that constructing a powerful robot is within the capacity of almost everyone, even those with a minimal background in electronics. This availability of hardware is progressively forcing robot enthusiasts to change their focus from building robots to programming robots. As this emphasis on software grows, the number of people interested...

A Robotic Puppet
November 2008
My interest in robotics has always been very diversified and I too have always been fascinated with the idea of creating the illusion of life. Perhaps that was a motivating factor that pushed me towards another of my hobbies — ventriloquism. It occurred to me that the techniques used in puppet construction might be of interest to many hobbyists interested in animatronics. A typical ventriloquist puppet is carved from wood or molded from some form of composite material such as plastic wood...

Prototyping Autonomous Robots
January 2009
Building an autonomous robot is a goal of many robot enthusiasts. If you look up autonomous in the dictionary, you will see terms like “self directed” and “self sufficient.” If you apply the first term to a robot, it simply means that the robot is capable of accomplishing a task without human intervention. The second term suggests a deeper commitment. A self sufficient robot might be one that is capable of repairing itself, or at the very least, capable of recharging its own battery so that...

A Practical Quadrature Encoder
February 2009
Building projects involving electronics and robotics is much easier today than in the past because many of the commonly needed subsystems are available as ready-to-use modules (we will call them HMs [helper modules]). For example, there are HMs for controlling nearly any type of motor (DC, stepper, servo) and HMs to collect environmental data (humidity, temperature, distance to objects). You can find switching power supplies, battery chargers, Bluetooth modems, and dozens more just by looking...
