School’s out! Its been an extremely crazy few weeks at school so I’m falling behind in all the documentation of the random tiny experiments and projects I’ve been working on lately.<\/p>\n

This morning I tried to make a two servo walker for fun. Something relatively uncomplicated. There are many tutorials online for one servo walkers (eg: B.E.A.M walkers<\/a>) with something called a bi-core, which is a simple oscillator that allows it to produce more complex behaviours, and which also involves some gears (which I do not have). So I decided to try to build a simpler two servo walker.<\/p>\n

This was my simple design for the walker’s feet. The script I used was a very basic edit to the default servo “sweep” script which probably needs no elaboration on how to use… because it just works.<\/p>\n

Assembling it together – I used an Arduino Uno, two mini servos, a small breadboard, some garden wire, mounting board and electrical tape. In my mind, having the front legs go in a different rotational axis seems to make sense so that the feet will lift off the ground. [Later I did try making them on the same plane (but opposite directions) and it did not work as well… but this is a design that can certainly be improved on…]<\/p>\n

One hour later and we’re already done!<\/p>\n

Not terribly complex but it does walk about slowly…<\/p>\n
