Toddler is a new addition to my robots. Toddler is a bipedal robot made of 2 servos. Its brain is a basic stamp 2 microcontroller. Here are a few pics of the robot. Here is some basic stamp code by which the robot can be controlled by a java programme. One can write plain pbasic programmes to make the robot walk and do things. Or one may write java applications to control it via serial port using serin and debug commands in pbasic. On the Java end you would need java communication api. Just use the serial cable which comes with basic stamp to hook up with the computer.

On the PC side you need an application to communicate via serial port. The basic stamp editor has a built in debugger, in which one can type the commands. But one would like to be able to control the software throug an application. I used java comm api to control the robot. Install it and the easiest way to get started is use the SerialDemo example which comes with the java comm api. Simply run the example, select COM1 and connect to port. Run the basic stamp, and you will be able to communicate to the basic stamp.
