Its summer time and that means tank tops, ice cream and bubbles! This robot friend makes a bountiful burst of bubbles all on its own.
Circuit Playground Express is the next step towards a perfect introduction to electronics and programming. We've taken the original Circuit Playground Classic and...

Sometimes we wonder if robotics engineers ever watch movies. If they did, they'd know that making robots into servants always ends up in a robot rebellion. Why even go down that...

These are standard '130 size' DC hobby motors. They come with a wider operating range than most toy motors: from 4.5 to 9VDC instead of 1.5-4.5V. This range makes them perfect...

This simple robot doesn't do a lot but it does it very well!
We have one DC motor with a fan attachment, and one servo motor where we connect the bubble wand. Every few seconds, the wand goes down into the bubble mix, then back up, the fan turns on for 3 seconds, then turns off and the process repeats!
