Python as a introductory programming language

Over the weekend there has been a in-depth discussion on creating a low cost robot for the Boy Scouts robotics merit badge.  One of the requirements is a simple programming language that a 12 year old is capable of learning.


I would argue that the requirement must also include a element of real world usability.  There are many programming languages a 12 year old can learn, unfortunately most of those languages are of no practical value in the real world. BASIC is a great…

What is the best kit to use as a introduction to robotics

I get asked this question all the time:

"Little Johnny or Jenny is around 10 years old and really wants to build a robot.  What the best kit to get him/her started?"


My answer is unwavering, the BoeBot from Parallax.  Parallax does an exemplary job of making robotics easy for kids of all ages. The BoeBot kit comes with a easy…

Programming in C for Small Micros

With Atmel, Microchip, and TI all selling 8 bit micros with 256K of flash for under $1.00, developing applications in C makes a lot of sense.  In the "old days" (5 years ago) developing in C for 8bit micros required that you purchase a C compiler, not anymore.  All three microcontroller suppliers (Atmel, Microchip, and TI) now provide free tools, including compilers.  


Atmel has …

Connect Four Robot - CMU Mechatronics Design Class Spring 2011

I took the class on Mechatronic Design offered at CMU in Spring 2011. It is an interdisciplinary class where students from different engineering backgrounds come together to do a project that makes them learn something about mechatronic system design. This year, the theme was a Connect Four Robot and a Can Crusher. 


There were seven teams that participated in the connect four playing robot design. We also had a contest at the end of the semester where robots competed against…

Robophilo Build Day 3

Unfortunately, the Parallax servo controllers were a bust.  

They worked perfectly with Hitec servos but would not work with the Robophilo servos.  The problem appears to be a lack of a series resistor on the servo signal line.
