Well I finally did it. I finally pulled the trigger and started to build a 5/6 axis robotic arm. This is an ongoing project so please check back from time to time to look at the progress and offer any ideas you might have who knows I just might include the changes. I have alot done so far. I will try to make this a step by step. If any of you need clarification or just more info on how i did that or where do i find that bit of software or that part etc. just drop me an email. So with that said lets get started. Please forgive any grammatical or spelling errors I am in a rush to finish this project please let me know if you see any.
If I win the Laser cutting machine. I will use it to produce more robots. After all even robots need skin. Not to mention all the projects I can make with such an awsome too. I use a larger one like it before and it was amazing the speed and quality of the finished parts.
So to begin with any robotic project no mater how complex you must plan, plan, plan, and then finally figure out or layout how you will go about it.. or "PLAN"...
Use your head when building anything. Use safety glasses when running mills drills or any power tool Your eye's are just little water balloons and can pop like a grape so protect them. I don't have time to create an instructable on how to replace your eye.
You're fingers hands and other appendages will lose any battle you engage in with a cnc, lathe or most power tools. Don't take them for granted. I have 30 years experience with machine tools and the building of robots I will try to make this easy. If you have a good design you can send out the drawings to have the major part fabricated fairly cheaply. If you don't know how to use a tool then learn, take a class, ask me or learn the trade. These types of machines have a mind of their own and must be respected, Safety first.
Now That the safety brief is out of the way lets get on with the show.
This picture is my last concept before i began. I created this layout with solidworks. that way i could test for any interference from moving parts in order to make sure they would all fit together just right. I also wanted to test for load bearing and lateral forces, as well as motor torque and loads. This information though not needed right away is a must for later on.
The mechanical layout is just a small piece of the design you must also consider all the programing that will be part of any robot you build especially a 6 axis robotic arm with inverse kenimetrics. More on that later. Once i had the basic layout I needed to make sure i cold afford the parts necessary to build this monster. I had to source the motors and find a supplier, as well as the gear/ drive train for each axis.
The motors i settled on were found on Ebay for 30.00 each. I bought 10 because i want to build more that one robot arm.
