How I Designed and Built A Forearm For My Shop-made Industrial Robot:

[@LordOfTamarac]

You haven’t inspired me to create a shop and start making things. I’ve had a machine shop and have been fabricating for years. You’ve inspired me to go back to school and finish and engineering program I dropped out of after high school. Seeing you work on these projects has made me realize how much I would love the change my passion into my day job. Thanks Jeremy, my application into the engineering program is currently pending, wish me luck!

[@gus473]

👍🏼 Good luck, stick with it! 😎✌🏼

[@Not-C-418]

I wish you all the Luck, its a great thing to do

[@beilkster]

Emphasize your hands on experience working in your shop. Most undergrads have little hands on experience.

[@artofeverything1816]

I did this and it’s been great! Now I can fix all those things I griped about as a mechanic…. maybe.

[@WampaReacts]

Where? I'm in the same boat and WANT to go back to school. I don't know where to start

[@bobvogel9916]

Jeremy, I'm a retired engineer. BS Mechanical and a MS in Computer Engineering. The kind of guy that has a woodshop and a milling machine and metal lathe in his basement. All I can say is "You are one impressive guy!" Keep up both the good work, and helping others along.

[@JerryRigEverything]

Lol. I was like "i hope he doesn't break a tap...." Oops.

[@game-f-un-limitedgamer8958]

Haha. Was thinking the same. I have broken a ton of taps by now.

[@farvezfarook3422]

[@rodchallis8031]

After working over 30 years, mostly in Q.A., in the auto parts supply industry, in semi-retirement I stumbled into a job doing Q.A. in a machine shop. Less high speed production, more big parts that demanded precision. One of the little things we did was finish off tapping holes the machinists were too scared to finish, lest they break a tap. I found it extremely satisfying to hand tap a hole to exact depth. I was watching the video, and thinking, 'hey, I'll tap those holes for you!' Never broke a tap, either.

[@hiddenlawyer]

I was admiring his tapping tool and that totally caught me off guard!

[@lesliedaisley7846]

Brother you are inspiring open a school teach the youths there are so many youths coming from those poor areas with so much potential but aren't given the opportunity someone like you can help steer their minds in the right direction.

[@tmote]

I don't have a lathe, but I do have a CNC table saw, a mill, oh and a fully articulating programmable robotic arm. Basic shop stuff. Jeremy, you absolutely are our favorite.

[@Jeremy_Fielding]

Its not often I want to turn something, so it is hard to justify the amount of space they take up. I am obviously thinking about it though LOL

[@tmote]

For sure, I just got a chuckle. Thanks for being such a great example of maker, curious professional, and especially being a dad.

[@freelookmode9837]

I can't stress enough how much I love your channel. I'm a licensed therapist, probably as far away from engineering as you can get. You should know that your channel reaches even beyond aspiring engineers to all sorts of people who love creativity and learning! Please keep up the outstanding work.

[@PiefacePete46]

Jeremy, you really are the complete package... I am retired, and have the ability to do as I please. What you have done for me is to highlight that the things that have restricted my progress in life were largely artificial barriers inside my own head. Now all I need to do is find the RESET button so I can start over with my new-found knowledge in mind. Thanks again.

[@michaeljones2965]

I always knew you were amazing since we were children. But these things on your channel are next level! So proud of you brother. Keep striving for more! 😁

[@MrLRankin2]

Congratulations my Brother. I especially love the way you included your children in this project. What better way for them to learn. Much Respect to you.

[@twotone3070]

The intern idea is truly a wonderful way of giving back, just where it's needed.

[@raymondjustice4214]

You blow me away with every video you share. You are an outstanding father / teacher / role model. I'm a dad too, and I'm going to Kiwico today, cause you make it evident and clear what I will get out of spending a few dollars!!! Keep stretching what I think I know about being a better human - we all need the challenge !!!! THANKS !!!!

[@togowack]

Buddy if you watch carefully there is a lot of money coming from somewhere in Fieldings operation how many people would even afford full time to build a robot while wife and kids in nice house like that with a CNC mill ?

[@Jeremy_Fielding]

Who said it was full time? And I am certain I say in the video how I paid for the robot! You should watch again. LOL I have a fulltime day job. The day job pays for the house :) The mill was 40 years old and broken when I bought it, but I am glad to hear you are impressed though! It turns out when you are willing to educate people for free, people with money want to help you do that.

[@togowack]

@@Jeremy_Fielding Sorry for being nasty Jeremy. I'm in the wrong... one suggestion, when you say the robot was so expensive, you made expensive decisions. My arm uses T.M. motors and hobby servo controls, and stepper motors for smaller axis. Total motor and control cost less than $1500 CAD. Arm is mostly laser cut out of lower guage steel. You machined most of your arm unnecessarily which is going to drive up the cost like crazy. You could also suggest using high torque 3D printed gear boxes which I am and it drops the cost of gears by 90%. Of course it is harder to build this arm but is much more affordable. Should mention I sat on the computer for about 2 years designing it before sending out the plans.

[@deenshabier7204]

@@togowack How is it even your businesses. You sound jealous.

[@togowack]

@@deenshabier7204 Honestly because anyone can throw money at something and make it happen. Go to school, get the training, find out better and proper ways of doing it before going on youtube to show it off to the layman. You will find many similar comments on these videos, just said 'nicely' by experts in the field that won't touch these with ten foot poles! There is no actual innovation here!!

[@willmorrison1022]

Sir, I must say that this is probably the single most impressive thing I have ever seen a single person accomplish. A team of people doing it would be more than impressive, but you doing this alone, I am truly humbled. I make instruments and some small tools to help in that, but this is a whole different level of complicated just to design, let alone actually fabricate. I am very impressed, and have been throughout the whole build series. And as always, your joy at things working is infectious. I also, as a fellow crafter and (VERY part time) machinist, feel your pain at the mistakes and mishaps. If I wore a hat, it would be off to you. Thanks VERY much for sharing this whole thing, it's been great!

[@nathaniellangston5130]

I have been a CNC machinist apprentice and now a Machinist and the thing I loved MOST was when I first showed up and I was expected to make mistakes and to just keep trying and ask questions! Doing an internship like this is THE BEST JOB in the world! You get to build so many different things and learn to do things you never expected to be part of the job you thought you sorta wanted to do! EVERYONE should do a hands-on machining designing repairing retrofitting type of job if they are interested in engineering!!

The curiosity, the trial and error, the success in the end. Just admirable.

As a guy that kinda started fresh, I’d be interested to hear what reference materials you found most useful during your education process. Any you’d recommend to others. I love a useful reference book.

[@TinyMaths]

Not sure if you've found your answer yet, but he has a video with the Title " Who is This Guy?" (it's from about 4 years ago) and in it he explains how he got into engineering after already running his own business, but becoming curious after someone piqued his interest. The person offered him a kind of internship and, if I remember right, on the first day he was given 3 books to study while he was on an internship. if you go to Jeremy's KZbin home page and search the term 'who is this guy' and you should find the video. I don't remember any of the book titles he gave (engineering isn't my area of interest), but it stuck out to me, because they handed him those books and he had to figure stuff out himself (and ask them questions when he got stuck). Good luck with your Journey.

Among all the cool things in this video, I love how little videos of the part in CAD show up as the part is made.

[@oh8wingman]

For tapping holes for components in your mill, make yourself a telescopic spring loaded follower with a point on one end. There is a centre on the back end of your threading handle. Simply centre your hole under the drive on your mill with the follower in place. Put your tap handle in the hole, lower your follower down so that there is pressure on the tap handle, lock the spindle, and start turning the tap in. The follower will keep everything in line so the chances of breaking a tap are minimized.

[@Jack-yl7cc]

You didn't mention changing the type of tap being used, so how are you avoiding the issue of the flutes getting clogged up on the standard straight flute tap in a blind hole while power tapping?

[@marshallwages5035]

Your channel is amazing, the time you put into sharing what yr doing is greatly appreciated.

[@lennartvolkaerts1873]

quick tip for machining, you first cut the contour of the parts and then drilled them. If you would do it the other way around, there would be less vibrations and and the part can't bend away from the drill. I think its very cool you embarked on this massive journey to build your own robot, looking forward to the next videos!

[@nickmagerl]

SolidWorks introduced your channel to me, glad they did. I love your way of thinking and your shop.

[@TopherTheLost]

Have you looked into a misting system for your CNC? At work we just refitted a saw and beam drill line that had been using a flood system for 20+ years. After the change over the tools are lasting longer and cleanup is easier without all the coolant.

[@Jeremy_Fielding]

I tried the misting at a friends house. It leaves a fog in the room after a while that I didn't like

[@semphony100]

There is no dought that harmonic drives are the best but they are expensive and not that available .I would recommend using cycloidal drives that you can design and build in your shop like we did and that cut down our gear boxes cost. Also I would recommend designing and building your stepper motor drivers and control system yourself , that also cuts down the cost a bunch.

I wasn't even looking at the video when that tap broke, but I knew what it was from the sound and instinctually uttered an "oof". Never a good feeling.

[@UkraineTrain21]

Awesome work. Just a hint, when tapping blind holes, you should use a spiral flute tap. This will pull the chips out to the top so they don't bind in the straight flutes.

[@leightonswannell6300]

Dude, you are my hero. I'm so glad you're making all these videos for everyone to see.

[@johnyoungquist6540]

Over the many years I have probably tapped a thousand holes and broken a few taps too. Now I rarely use a tap handle because you can side load and snap the tap. I now use to some peoples horror a battery drill usually in high gear if I want less torque. You can even use the torque limiter on the drill. Tap breakage comes from side load that you tend not to get when the drill does the turning. Using a drill is scary at first but it really works. If you bottom the tap in a blind hole you will probably break it but otherwise if you keep the drill straight the process works. The drill likely doesn't have enough torque to break the tap but if you bend it sideways you'll snap it. I converted to drill tapping a few years ago and I am inclined to use it for most operations. I know it seems crazy but it works. JY

[@sgsax]

Any interns in your shop would certainly learn a lot and have fun doing it. I know I do just watching your videos. Thanks for sharing!

[@lordRW]

For your next welding of aluminium, remember that aluminium should always be cleaned with a brush before you start welding, and dont wait long from cleaning it til you weld it, as it causes issues with welding pretty quickly, also heating up the whole part before welding helps a lot.

[@Sirmellowman]

So I can give you a very valuable tip when tapping, you need to clear out the chips with compressed air or something when the tap gets loaded up. That's why you broke it.

[@stevebonser4414]

As always nice work Jeremy!

[@TheRealBanana]

16:00 I am interested in how you solved this issue as it seems similar to an issue I was having with a camera mast I designed. If the camera mast base moved at all it would put pressure on the cheap servos and they would change position a bit. The arduino servo library I used would then try and correct that movement and would induce further oscillations. My solution was just to use a spring to dampen everything at the expense of loading the servos a bit more. Can't wait to see what you have in mind for this arm in the future.

[@kemaruproduction]

Jeremy your are awesome 😎. Being a mechanical engineer PhD in computational mechanics and MSc in control systems, I have to say, you nailed it man! What do I do? Just academic papers man. It must be really fun working in a nice workshop all by yourself just creating.

[@PaulThomas-qo9vy]

Great robot arm vid.! Suggestion for chip removal: wet vac with sump pump inside to return coolant to coolant reservoir. Also adjustable flow air nozzles aimed toward vac pickup nozzles to help "push & pull" the chips. That vac can really speed up post machining cleanup too!

[@kylewellman402]

I think i can speak for a very large crowd here that you should reconsider the "plans". It doesn't have to be an exact replica, but even generalized design concept, maybe how to setup the 6 axis and connect them together mechanically, different thoughts and problems that need solved during the build (i know you went over the majority throughout the video series, but having a guide with text in hand is always nice too. Maybe even just a walk through from an engineers perspective with possible sources for the math and mechanics involved. Micro Center sells little stepper motor kits that come with 3 motors, and they also sell H-bridge stepper driver boards. That coupled with a 3D printer could make for some very educational small scale learning experiences for us and our children. I have a good background with robotics being a controls engineer, starting as an industrial technician, doing everything from PMs to electrical/mechanical troubleshooting, to programming, and i would still love a walk through from your perspective to make a miniature 3D printed robot arm to hopefully fascinate my older step kids, and my 3 year old boy. Even without, i love your videos and all you already do. Keep up the great work, you truly are an inspiration!

[@development7620]

The stuff you do is Amazing!! How inspirational for the next generation

[@RambozoClown]

One tip for order of operations is to do your drill cycles before you profile the shape. That way the part has more strength to resist the drilling forces. I was thinking of the wrist area where you drilled after cutting that into a tab that hangs out in space. Keep up the great work. Servo tuning ain't easy for sure.

[@catalinhristea2358]

Te older generație of robots used springs to balance axis number 2 - first arm- the problem with spring is that depending on arm configuration the force need to change. Also a spring without a dampening sistem is a resonating mechanism. Newer generation of robots like abb kuka use a pneumatic balancer.

[@jimkirk360]

It's not always about the destination but the journey.

[@codydorman7983]

You should power tap your holes to avoid breaking the taps the mill is more accurate than by hand keep the torque straight... on blind holes mark the depth
