Building a 6 Axis Robot Arm from Scratch - 1

[@simonwirz8886]

As a mechanical engineer myself I truly appreciate your build quality and your overall design. Well done. I definitely stay tuned.

[@EngineeringSpareTime]

Thanks - I appreciate it :)

[@NolanKwok-n1f]

@@EngineeringSpareTimedo you sell the design or whole robot arm?

[@Engineerd3d]

That is certainly a beautiful machine. Please share more.

[@ryo-kai8587]

All of these parts are utterly gorgeous! So clean and elegant despite their complexity. Can't wait to see it in action, and completed with all 6 axes.

[@EngineeringSpareTime]

Thank you :) until the servo drive is working, I’ll continue with the mechanics. Next video will be about the drives and probably some first movements.

[@andresroc1567]

Wooow that mirror quality and the design is really beautiful. I’ve enjoyed every second of the build. Thanks for sharing!!

[@EngineeringSpareTime]

Thank you! A new video about it is coming in the next weeks :)

[@Thorhian]

Dude! This is awesome! Your content is quite inspiring to me, so thank you. :) Now that my semester is over I can get back to working on my own CNC mill.

[@EngineeringSpareTime]

Thanks! That’s nice to hear. I wish good success with your build

[@8bit711]

Got a new fan here. Had to build my CNCs first but its all for the same reason as you;)

[@BebenX]

Holy shit, this is truly incredible work!, please continue to share your projects.

[@0m1d]

Can we expect a part 2 of these build series? Nice work btw👌🏼

[@EngineeringSpareTime]

Yes, I’m in the process of finishing my studies. In a few weeks I’m planning to create more videos again. The robot is running now, so there is lots to talk about :)

[@yyunju]

@@EngineeringSpareTime hopefully you continue doing updates. ! High quality work !

[@BadPractices]

These parts are gorgeous.

[@mysteryMachinePL]

Huge kudos for design. Especially on printed parts.

[@R_802]

dude please upload a part 2!!!! This is so interesting!

[@PiefacePete46]

Tremendous! I guess you know how your spare time over the Christmas / New Year break is going to be spent! Thanks for the video... Liked, already Subscribed.

[@EngineeringSpareTime]

Thank you - I appreciate it. Yes, I‘m going to start with the servo drive PCBs.

[@Rami7605]

wonderful project

[@modris2980]

Beautiful work. A few questions here. 1) Calculated weight of each joint and robot arm as a whole and expected lifting power from servos of each joint? Gripper (last joint) lifting power? 2) Cycloid gears, so almost no backlash? 3) You say 6 axis does that mean a true 6 axis with all the mathematical calculations of forward and reverse kinematics that go with it? 4) Will you write your own program from scratch or use something as a base?

[@noatreiman]

so frickin good wow!

[@swannschilling474]

This is great!! 🤩

[@EngineeringSpareTime]

Thanks! Your robot too!

[@libor-vitek]

Beautiful. What aluminum alloy you used for milling, please?

[@markos3803]

what was your approach with bearings? i thought i saw both thrust needle bearings as well as some ball bearings, how were those configured?

[@dusty_dreams111]

beautiful parts.

[@Dannerrrr]

I'm really curious about the wrist system.

[@MXVofficial]

Hello, this is awesome! I want to build an arm as well. How did you program the motion of the robot?

[@AmonadaLP]

Will there be a part two? Would be really awesome!

[@hungrythundr4892]

I’m relatively new to machines and cad in general and I recently got a cnc machine for a good price. It would be great if you included a parts list so I could get a bit better grasp on this because it truly is amazing. Thanks!

[@EngineeringSpareTime]

Thanks! I want to see how it turns out first, if everything is working as intended I can provide a overall description of the project :)

[@inevitableinventions]

Any indepth video coming on this soon? 🙏🏼

[@grahamnash6701]

Trying to make a robot for school, can you link the motors and encoders/electronics you used to drive them?

[@Consulting157]

Broh this ist so nice to see, do you got any stl‘s or something u would share?

[@jamarperrin4409]

I love this!!!

[@BabaCAD]

I hope you will use harmonic drive reducers to get a good repeatability (and to get more torque also) for your robotic arm. For industrial class robotic arms of this size repeatability is < 0.1 mm and payload at least 5 kg.

[@EngineeringSpareTime]

The system is based on belt transmissions, this reduces cost drastically. With the control strategy I will use, it should be possible to take into account the flexing introduced by the belts. .. At least 5 kg: This is mostly restricted by position and acceleration in industrial robots. I am planning with 3 kg in all poses

[@01Binary]

What is the absolute encoder you used? I use hollow shaft potentiometers from P3 America in mine

[@EngineeringSpareTime]

It’s an RLS Orbis magnetic encoder

[@cleisonarmandomanriqueagui9176]

Servos motors number serie or name ?

[@funivieitalia]

Which cnc do you have?

[@EngineeringSpareTime]

Check out my video on building it :)

[@i-make-robots]

so close to those tall bolts~~!😱

[@filipstojanovicmechanicale9265]

The masterpiece.

[@pododododoehoh3550]

We need more

[@samo6401]

Where do you get your aluminum plates?

[@EngineeringSpareTime]

I got them cut by a local laser cutting service. This is not too expensive and it would just take too long to mill the overall shape on my cnc - not worth the time.. other than that, I get the Aluminium in an online shop that’s sells even small quantities for a reasonable price

[@jcborges7799]

Boa noite ! Você tem o projeto para disponibilizar ?

[@thelovasky]

Um br

[@steve5nash]

sick

[@InterdimensionalWiz]

very smart.

[@thecreatorofbeauty]

What could be the cost of something like this ...

[@EngineeringSpareTime]

This depends on the quantity, version (double position measurement..) and included software. To name a range (hypothetical selling price): about 3-6k. Just the hardware incl. drive system would be the lower end . The system can further be optimized for production though..

[@waimak7507]

What's the payload on this arm?

[@EngineeringSpareTime]

Max. 3kg

[@9782ravi]

Which lathe machine you use?

[@EngineeringSpareTime]

It’s a Wabeco D6000

[@9782ravi]

@@EngineeringSpareTime thanks

[@emremicrosoft5321]

The biggest problem is that such beautiful projects are not open source. For-profit companies already have their own projects, they cannot watch these beautiful videos and say "wow". But we students receive education in different branches. For example, I am a software developer. Now, if the files of this project were ready, I could print it on a 3D printer and try to develop software on it. But this is not shared as if it were a state secret. What do you think I should do? Should I study mechanics at the same time?

[@jamarperrin4409]

Could I commission you for a helper robot arm for filming product reviews????

[@SantaDragon]

I miss somehow the demo of the arm ...

[@EngineeringSpareTime]

Yep, u are right, this is just part 1 - I am working on it. The next video will follow in the next few weeks. You can check my Instagram @engineeringsparetime for incremental updates, there are already some short videos of the movement :)

[@abraham5148]

I would like to try to build with 3d printer.

[@krogulec5451]

We have the same taste, you and i. It's not ambition, it's ambitions opposite...

[@SaifurRehman-y1m]

CAN YOU GIVE ITS MEASURMENTS

[@williamhuang5329]

Hanzhen harmonic drive gear , over 30 years experience , robot arm gear ,,

[@MrEngineer_]

It's not being built from scratch😭😭😭

[@EngineeringSpareTime]

It is :) what makes you think this?

[@funivieitalia]

Which cnc do you have?

[@EngineeringSpareTime]

The CNC is selfmade - there is a video about it too :)
