4 DoF mechanical arm mounted on a tripod

Is there any update about the contest?

I&;m working on it, I will submit my design soon.

Are available to design a mechanism which fully driven by pneumatic circuit?

Hey, can you provide more details on the end effecter&;s use and what could be the source of arm movement like motors, mechanical links etc?

Hi @Lucian and IBM Resereach. Thankyou for extend this contest. But if possible, as engineering design, this is need more compex information. All of designer got less information. so we are a bit confused where we have to go. what type of motor you are using for. this is will impact the total weight. as you know we are using random motor for make the arm move. we have to know where we go, what part that we use. so we design base what you are using, not what we want because this is your project. so we are actually follow your requirment. please understand this. im really happy if i can do contribution on your project. but i need more design requirment.

Thankyou all. Keep safe right.

Best

Hi all,

We talked to the client and extended the contest a few more weeks so you can come up with more ideas, so he could choose a winner at the end of the contest.

He will give more feedback on why some of the entries do not meet the requirements.

Thanks,
Lucian

@Walxo As I said earlier, we were looking for innovative ideas and not copy-pasted ones. We did not get what we were expecting.

@Sam_Mayo Eng. Sorry. we had already extended it so can&;t extend more.

Could you add five more days for those of us who didn&;t participate?

To IBG Researsh.Gents,You don&;t want genius ideas and don&;t know what you want.This case is precedent in Cad Crowd community.

@Sava I understand that it can be heartbreaking. All the efforts going in vain. I tried making all the designs open but I am not able to because Cadcrowd doesn&;t allow me. We were really hoping to get some really innovative ideas from the community but we failed. @Paulf Thank you for great suggestion. We tried to be clear with all our requirements and constraints in the description and we were also actively clearing doubts in comments and through messages, so that we can have a really design. Please understand that we also invested a lot of time and efforts running the contest and it is hard on us also, not getting something that we had hoped for.

Dear IBG Research, thank you for organizing the contest. I would like to suggest for next time to minimize time and effort consuming issues, please specify more requirements. The less precise the requirement, the more variance you will find in your results. Plus if the award was already mentioned, then the rule of winner selection should be applied, otherwise you will lose the credibility.

OK, why you don&;t make the entries to be visible - let us see them! All this conspiracy is so boring - blind projects all the time... If no one wins let&;s just learn something from each other.

Thank you all for your great efforts. We evaluated all the entries but we did not find most of the entries acceptable. The reason could be either we did not give enough time or the explanation was not clear. Hopefully, we will be able to work together next time.
All the best for your future.

would be possible to extend the contest two days. I am working on the design.
Thanks,

Do we need to select actuator(Motors, sensors, Gear box) etc??
If so what is the required accuracy and speed for the system.??

@RamaKD Identical is preferred but it can be different.

must both arm have the same length? or can it be different?

Thanks for extending the deadline

Has the dead line been extended?
