After much thought I hit upon a simple idea, rather than build a bracket, how about altering the servo casing its self. For a simpleton like me this seems like a lot of effort, my workshop skills not being that great and neither is my patience, I didn’t want to go down this route. The first problem of designing your robot arm is how do you mount the servos? Most kits tend to use some kind of bracket that the servo is mounted into, the armature then mounted to this bracket. Where does this leave me, apart from being too poor to afford a robot arm kit? Well I thought how hard can it be to design and build my own robot arm? Surely I can do it for less and if it works I can publish the results and schematics rather than just a video of it working. I also looked at servo brackets and constructor sets but again whilst the odd piece is OK trying to get the parts for a robot arm is too expensive. I then looked at getting a design fabricated but most of the designs I’ve seen rarely give you or decent assembly instructions. So firstly, I had a look around for robot arm kits that could be brought rather than fabricating the parts myself – I found the prices to be extremely prohibitive.
#ROBOT ARM ARDUINO CODE#
I’ve included some very basic Arduino robot arm code along with robot arm design / blueprints and measurements for you to download and build (on any material). The robot arm has 3 joints and moves in the X and Y dimensions – not the Z (although I will build this in subsequent versions).
I already had the Arduino Duemilanove ATMEGA328, some foamboard, tools and glue. I have constructed a basic Arduino robot arm using 3 servos to build and it’s very simple that I think anyone can replicate and build this.
