Hexapod.


Being a little a little bored (although that`s the wrong word) this afternoon, I considered the 3 servos I had in a box after replacing the ones in my robot arm, and came up with the idea of making an "insectoid" robot with them.

needless to say that after some thought, the careful application of some super glue, servo modification and wire bending, I now have a working Hexapod robot emoticon

I kid you not! about an hours work that folled about an hours thought (you can bypass that process now) and you have a working robot emoticon

I`ll post pictures of it when I can be bothered to mess about with that photobucket thingy again.

but if you Do have some servos laying about and a controller for them...
well you can make one too!

Here, for more Explicit instructions use this: http://www.pololu.com/docs/0J42
it`s more or less the same sort of thing only mine`s about 4 times the size and 10x the power (you work with what you have!).

don`t forget though, you MUST set the limits on the servos!!!!
else they will rip the robot apart in the blink of an eye, 45 degree movement is all you`ll need on any servo used, more than that and you`ll be crashing into bits emoticon

Re: Hexapod.


Let me alert you about servos. Ive been flying small aeromodels a few years ago. Ill tell you to avoid cheap plastic gear servos, the plastic gear brokes so easy...

As the HITEC servos above, its a carbonite gear, stronger and expensive than normal plastic gear. But, also, you can buy metalic gear servos, more realible and not so much expensive.

The more the flexible legs of the spider, the less stress to the servos gear...

Re: Hexapod.


I`v finally got my controller board and batteries mounted, and after a couple of days learning how to code for the board, I`v got the sucker Walking now! emoticon

next job is mount sensors on it for collision detection, I thing I`ll go with IR rangefinders, I already have the algorythms for forwards / backwards left and right turn, so it shouldn`t be a problem getting a sensor input to jump to the correct response subroutine.

oh yeah, it scares the hell outa my mother in laws dog emoticon

Re: Hexapod.


meh, I decided to make a Remote Control for it instead using a pair of 433 MHz RF modules (Rx,Tx) and an encoder/decoder pair of HT12`s.

here`s the Final pictures emoticon

That is the end of the story (...For Now!)
