Spherical Quadruped Arduino Robot

Posted on by

[Greg06] started learning electronics the same way most of us did: buy a few kits, read a few tutorials, and try your hardest to put a few things together. Sound familiar? After a while, you noticed your skills started increasing, and your comfort level with different projects improved as well. …read more

It’s a Spider! It’s a Droideka! It’s Both!

Beware, arachnophobes, the robots are coming for you!

What else would you be expected to think if you watched a hexapod robot display its best Transformers impression by turning into a wheel and pushing itself in your direction? The BionicWheelBot — developed by [Festo] — should rightly remind you of the cartwheeling Flic-Flac spider, the main inspiration for the robot. Of course, Star Wars fans might justifiably see a Droideka.

The BionicWheelBot can — almost — seamlessly transition between crawling around on six legs, to literally rolling away. To do so, its three pairs of legs sequentially fold up into …read more

Everything You Wanted to Know about Transformers (But were Afraid to Ask)

Posted on by

[Jim Pytel] has a lot of very good instructional videos on his channel, and he recently added one you’ll enjoy on transformers. You probably know that transformers convert one AC voltage into another AC voltage. Some step up voltage, some step down voltage, and others simply pass voltage through but isolate the input from the output.

The 40 minute video covers basics including how the transformer works, the meaning of the turns ratio, and how transformers reflect impedance. You probably should understand how to compute AC power, but if you need a refresher [Jim] has a video for that, too. …read more
