Hey guys,

  Does any one here customise their servos? I'm just wondering because I've seen a lot of robotics joints have servos that turn on both sides rather then the Remote control style servo which generally only turns on one. When building a robot like the dancing 8 legged (mambo number 5) robot in the blog section or a robotic arm, it would be structurally stronger to have the ones that spin on both sides right? So can you customise a standard servo to spin both sides like that? Sorry its all pretty new to me.

For example:

For making stronger joints like:

I havent customised any of mine because they are just cheap 1 sided ones and I have usually used them as main drive motors anyway (like for wheels etc).

Most of the cheaper servos will be 1-sided while the more expensive ones (like the digital one in your pic – top right) seem to have a thru-axle option.

You don't actually need a thru axle servo though for a lot of stuff depending on what you are doing. Lynxmotion make a number of servo brackets (like in the leg pic above) that add another joint point onto the servo so you can use a single sided servo and it makes it double.

Their servo-erector kit seems to be pretty cool and I have been meaning to buy some of their stuff for a while (but I keep spending all my money before I can order some :)

Thanks for the info man! Those servo brackets sound good and look like they can keep things on the cheaper side. I'll deffinately look into them for future projects when I get better.
