Agree!!!

Young and ritch in order to pay at least 10 plastic injection molds and send 1400$ in robot arms to a channel that doesn't make a positive review for them...

@@eduardoanonimo3031 1400 USD is msrp, not the actual cost of hardware and assembly. Total cost of this robot, especially when they use high quantity (1.000-100.000) injection molded parts would be around 200-250 i guess.

@@mariusb6035 Exactly!

I get the impression that young or not the designers are, whoever made it thought : Man why do we need to use expensive motors when we can just use cheap servos? They all just spin right?

@@giantbee9763 And then backlash comes and repeatability get out of the party...

yes, especially on the first 2 joints, where joint weight isn't important, would have made a huge difference.

A cheap steppers even without encoders would be better

Steppers are usually too heavy for that style arm. They do have their "pro" series arms which they claim to have brushless motors in the joints, but the price skyrockets.

Yes, geared stepper motors will be able to move more precisely, handle greater load and run much quiter than the servo motors. Though skipping steps would still be a problem.

@@TechBuild Closed loop steppers would be the cheapest option to mitigate missed steps

I am glad to hear that it was helpful!

trolling is a art

Glad to hear that!

if i could build a durable arm that looked like this with the good cable management, i would be happy

No, it wouldn't even be able to lift the phone.

Thank you for saying that. We definitely see the higher expectation on the servo performance and the self-innovated servo for this very small size in now under developing for that purpose and we are looking forward to introduce it to our users soon.

naw man mount one on each shoulder

The thing is, if it is the same price, the quality would be the same. Precision comes from quality motors, bearings, transmission and all other mechanical parts. BTW, there are good open-siurce printed 3d designs, but they are more expensive. There also are designs based on rc servos, which are basically toys.

Build my robot arm (from my coming video). It is going to be cheap, and uses steppers. Video will be published next week (normally).

It would be difficult to replace servos, because they use special servos, with special communication protocol. So if you replace servos, you would need to replace electronics and software. Thus it would be easier to build the robot arm from zero.

Do you think those servos are in a CANBUS or something?

No, I checked the package multiple times. This is self taping screws, and from look of the hole, we can definitely say, that no screw was there. :)

Most probably. :)

Had my fair share of trouble with elephant robotics - the raspberry PI comes completely in Chinese incl. the test program, most programs not working - the documentation is incomplete / out of date - claiming everywhere its an open source robot arm for makers and educators but they aren’t. I wanted to fix the atom interface and therefore the code and they replied for “company secrets reasons” lol they wont do that. They likely don’t want to see how some juniors jammed some code together. Which explains why you have trouble with the python code. - The first robot they send me was 3d printed, still charged full price. - This company loves false advertisement. From load, to speed, to repeatability to components used and marketing with open source while its absolutely not. So buyers beware. If you want to see more about the issues, go into the official mycobot facebook group and scroll through. It’s a company that sells and forgets hardware without proper software skills… 💸

I think that is changed; I've seen that stability has improved. On the site they claim ROS2 and moveit. Also, they have an industrial type of application Roboflow. I am also a teacher and I wanted to use those for education. What would you recommend using for education on a budget?

Hey! I know your comment is from two years ago, but I would love to know what you would want in an educational robot? What would be the 'must have' features, and the nice to have features? How many students to robot would be the best ratio? And what would the budget look like? Cheers :)

He also wouldn't want to develop something so poor in the first place.

They could have just 3d printed the body of the robot.

Он не русский. Сильный русский акцент. Но он немец из Швейцарии.

That might be worth a followup video ... when you review a commercial product, does it get worse after the first few hours/1000 moves/months of calendar time, etc? Not so important if it is just for entertainment, and not worth delaying the reviews ... but worth doing a followup later. (Also worth saying whether those additional hours were just to test endurance, or because you found it worth using for something.)

Yes, there are LEGO pins designed to connect effector and Joint 6.

Точно :))

Agree!

3 linear, 3 rotational, freedoms

@4:21 there is a noticeable sag of joint #4 with payload compared to the one without. Well, I should have waited until the next segment with overlayed videos. Nice job! 🙂

ha ha I yes it does

They don’t give me anything after review. So I can say what ever I want. And this review rather negative, than positive.

What do you mean? I gave them honest review, and it rather negative. In conclusion, I told that this is an expensive toy. I don’t see other good application.

Do you think this robot arm is payment? I don’t need such robot arm. I have no use for them. Do you agree to work and be payed by robot arms? Do you think I can sell them? But what about my time, spent to sell them?

I appreciate the transparency of book reviewers who say "I received a review copy, but was not otherwise compensated." Skyentific's wording was less conventional, but I think it was sufficient, since he did acknowledge getting it for free, and at least implied that he got to keep them (not true of all reviews, particularly for expensive products).

For me, it is impressive, how bad it is.

@@Skyentific haha okay i seeeee! yeah that makes sense! :-D

probably because people say "10 dollars" and not "dollars 10", even tho $ sign as a prefix is indeed the correct way, it just makes a lot less sense

Yes! :)))
