theres no stopping you now.

i really like this. great use of the bracket, good to see more uses for it. could have done with something like this a few months ago. :neutral_face:

will you be following this thread with a vid? 8)

3

I think itā€™s kneeā€¦ tow! :laughing:

4

Will do. Once I get some code loaded on it. Probably tomorrow or so. 8)

ā€¦Sigh. :laughing:

5

Maybe this would go well with the hip rotate? I have my doubts if it will walk any better than a regular brat though. Thereā€™s just something about reverse knee bipeds that really adds to the cool factor.

6

A day late, a dollar shortā€¦ No, wait. Just a day late. :unamused:

7

i agree, works pretty well. nice work. looks smart too. 8)

8

Yep. That it does. Keep in mind that itā€™s using HS-425 servos, so thereā€™s going to be a limit to how well it moves.

I did have to make one modification from the images I posted, which was to spin the feet around so that the longer side was in the back.

I loved the video, but I also loved that music!! My kind of music. 8)

It walks better than I thought it would. By the way, is this project an offspring of those new hexapod leg designs. I notice it uses similar brackets.

11

I have an idea James,

You could use this bracket:

And make a scout like bot with the Brat torso, kind of like a Brat hybrid. If sucessful, it could be called ā€œScout Jr.ā€ You could also include the LPA design you posted the other day and add that on the top, and use the scout aluminum feet as well.

Yeah, I was considering that for a 4DOF version. If I used it, however, I would have to modify code! :imp:
Not to mention that the Scout feet are larger than the BRAT feet, so they may not fit using the 3" aluminum channelā€¦ But I wonā€™t say anything about that. The low profile axis may work though.

Not really an offspring, no. It just happened to happen at the same time, since we got a new bracket. :stuck_out_tongue:

Haha, the song is Isolate by Sybreedā€¦ most people donā€™t particularly care for it once the vocalist opens his mouth thoughā€¦ :laughing:
If you know of some more stuff like this though, maybe you could PM some band names to meā€¦ :smiley:

13

I donā€™t know of any band names and I prolly would not like the voice. I like metal sounding tunes though.

I did not know the scout feet were bigger. I learned something today!

14

Yep. The BRAT feet are 2.50" x 4.75" while the Scout feet are 3.00" x 5.00". :wink:
