MorpHex, a sphere formed morphing hexapod

Thanks Jonny, but there are still 27 days left of this month, so you never know. Its looking good though! :smiley:

Man… you have to win… really…!

MorpHex is making its way around the internet now!

This is such an awesome 'bot, good luck with the competition! :smiley:

Thanks Beth and Eric!

Yeah, its fun to see so many people that find it interesting. I believe “hack-a-day” was one of the first to post about it. I get very humble to all the people who vote on my project.

I saw the last video… it’s just WOOOOOW !!!

Thank Zenta to make me dream :slight_smile:

you got a vote from me. Awsome bot, nice thinking out of the box:)

Thanks to all of you who voted on my project!

MorpHex became the April’s winner on the Boca Bearings Contest. :smiley:

Congratulations Kåre!

Good job!

Thanks Alan!
X-ing my fingers for the final at the end of this year. At least my wife are going to get an IPad :laughing:

Hi,

It’s been awhile since I’ve done anything with MorpHex. For some months ago I decided to make a new version. A more symmetrical version. This mean 12 legs and 31 servos (24x 5990, 6x 5980 and 1x 5645). The leg design will be very different though. At this moment I’m not even sure if I’ll ever make it work, the total weight worries me a lot :confused: . I’ll post more information when I’ve done some more progress, also with some new pics.

Lately I’ve been playing a lot with my robots together with our toddler (soon 2 years old). He just love them all, especially the A-Pod(s). I think he misses MorpHex a lot though. He is also one of the greatest fan of youtube. Every day he ask me to watch “bobots”. His favorites is the cool robots from Boston Dynamics. Talking about youtube. MorpHex part III became pretty popular, a couple of weeks ago one guy posted about him on reddit.com and suddenly the video got 300k viewers in addition. At the moment its getting close to 1,2 million viewers! :laughing: A few days ago I discovered a cool version of the video. Quoting Ludiotic:

Here is the video (turn on sound). My kids loves it, he sure did a nice job syncing the sound to the movements.

Stay tuned for updates on MorpHex MK2.

Laik liked it!

thats great!!!

A few days ago I got the great news from the Boca Bearings company that my contest entry won their grand prize! More information about the contest results can be found here. I do feel very honored for getting a prize like this. I’m also very humble thinking of all the other great projects that was submitted to contest. One of my favorite projects was the human powered helicopter, a very impressive achievement indeed.

As you may have noticed I’ve not had much time for updating my blog or this forum, its mostly caused by little free time.(repeating myself here… :unamused: ) When it comes to the MorpHex project I’ve done some progress on the next version of MorpHex, called MorpHex MK2. Or maybe I should call it Mark 3… You see, I’ve had a few setbacks lately. I earlier mentioned that I would try to go for a fully symmetric version and using a completely different leg design. I did some progress on that attempt, but after a while I realized that it wouldn’t work under one critical condition; transforming from ball to hex. Here is a rather low quality picture of a very different coxa with dual femurs I made under this attempt:

After a lot of thinking I came to a decision of going for an asymmetric design again. To be honest I don’t think a symmetric version of MorpHex would be very appealing. You see, a symmetric design mean that the upper and lower leg sections share the same coxa servo. So when walking the upper sections always need to follow the lower legs. An asymmetric design where the upper section can keep the half sphere shape is something I really liked with the first version. So this time the I’m going for an upper section with 2 DOF. I do hope this will work better.

So far I’m still working on assembling the lower leg sections. I’m using a slightly different coxa design (don’t have any pictures ready for that yet) and a tibia bracket that are going to make the sphere sections much stronger. A picture of some the new brackets here:

There are still a lot of work left when it comes to hardware assembling, calibration and programming. I’ve not decided yet if I should go for the ARC-32 + SSC-32 combo yet. The ARC-32 should handle 31 servos fine, but during my last calibration on MorpHex I noticed some issues where the calibrated values suddenly disappeared during the process, very annoying. Kurt, I’m not sure if you have any ideas whats causing this? Luckily I the old values was still visible on the terminal window, so I could just re-enter them. The SSC-32/Visual SEQ combo might be a safer solution for me during calibration. I also believe some more program space can be available using the ARC-32+SSC-32 combo. Don’t think we need the “extras” then.

Now, If I only had more free space in my workshop for a machine like this :unamused: :

Again congratulations you deserve it…

Nope: don’t know what is going on, maybe an issue with the EEPROM?

Kurt

Thanks Kurt! :smiley:
I also thought there might be an issue with the EEPROM, I did never experience this on an ordinary hex though only when adding the extra servos. hate random errors though. I might go for the safe combo then.

Btw, I hope you had a happy new year!

Didn’t say in on Facebook but i did see that you won… :wink:
Well… i think all people here will say the same… You deserve it… !!!

Thanks Eric!

I’m considering a CNC mill, but they are a bit big and heavy. Maybe a router instead? Do you have any good tip for a complete machine? Don’t want to build one myself…

I am looking to change mine.
Not quite satisfied with it… too soft.

It all depend on what your expecting to cut and do with it.

Thank you, so far so good.

You could go completely nuts and move to the wild side! Like an Arduino Due or Raspberry PI or Chipkit Max32… Then you will have lots of code space to play with!

Kurt

Massive Congratulations. What a fantastic end to 2012 for you. Look forward to seeing how you use your prize. :wink:
I like that you are continuing to develop morphex. What a great project.

Well done my friend.

:wink:
