Building a 6 Axis Robot Arm from Scratch - 1

Homemade/ DIY aluminium six axis robot arm from scratch with servo drives and absolute encoders. This video shows the design, machining and the current status of the build. I started with building the first 4 of 6 axis, to be able to make some changes on the way if necessary.
The idea is to design and machine the structure of the robot from scratch as well as the servo drive system, modeling and control (programming). The main goal is high performance at a low price.

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

@EngineeringSpareTime 3 года назад

Thanks - I appreciate it :)

@Engineerd3d 3 года назад

That is certainly a beautiful machine. Please share more.

@R_802 9 дней назад

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

@ryo-kai8587 3 года назад

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 3 года назад

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 2 года назад

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

@EngineeringSpareTime 2 года назад

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

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 3 года назад

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

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

@PiefacePete46 3 года назад

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.

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

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

@EngineeringSpareTime 4 месяца назад

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 :)

@modris2980 3 года назад

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?

@hungrythundr4892 3 года назад

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 3 года назад

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 :)

@AmonadaLP 9 месяцев назад

@BabaCAD 3 года назад

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 2 года назад

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

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

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

@01Binary 3 года назад

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

@EngineeringSpareTime 3 года назад

It’s an RLS Orbis magnetic encoder

@samo6401 3 года назад

Where do you get your aluminum plates?

@EngineeringSpareTime 3 года назад

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

@funivieitalia 2 года назад

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 :)

What's the payload on this arm?

Max. 3kg

@thecreatorofbeauty 2 года назад

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

@EngineeringSpareTime 2 года назад

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..
