hello all
After a long building time (uncounted houres during one and a half year) I
finally assembled my Johnny Five robot the first time.
This was a great feeling looking to the robot and I will share this with you.I
found a lot of inspiration on Lugnet and Bricklink.
J5 is made of 8 modules and his total weight is about 13 kg. I think its a large
style model :-) It uses a number of motors and gears:
- 5 in each arm (shoulder, upper arm, ellbow, wrist, hand)
- 3 for the head (turn, two pistons)
- 2 for the treads
- 1 for the upper body
It was my intension to build J5 as close as possible to the "real" J5
(http://www.johnny-five.com).
My special thank is going to Eric Sophie and Rosco. Eric's JAMA gave me the
"kick" to start buildung J5 using LEGO and learnd me a lot of construction
technics. And Rosco showed me the idea for the treads with his MOC CC2800.
J5 is not almost finished now. There are a ot of little things waiting to be set
up right. I also have to wire the electrics and learn to programm RCX.
I also have to re-construct the joint for the upper body, It is to weak to hold
the whole weight of the body, arms and head.
The pics are located on brickshelf

Hi Steven, that is very cool! I'm glad I could contribute no matter how small.
I've added .technic to the groups cos I think they'll like it over there too!
Can't wait to see the finished robot - I remember Short Circuit from when I was
a kid.
One question I have, how smoothly does it move on those treads? I found my crane
was pretty jerky when it moved.

Hi Steven
I remember seeing this a while back and thinking it wasn't even Lego, until I
looked closer, woof. Woof, woof. And not only is it a great model but then you
roboticized it as well. Cool. I can't wait to see when your done. This will
be truly an awe inspiring creation. Any chance for video of Johnny in action?
I appreciate all the in progress pics as well, fun to look at.
I looks like the treads work, but how is the action? How do those hinges hold
up to rolling around?
Wow, good job, can't wait to see it done.

Hi
Thank you for your feedback and for adding my post to .technic.
Yes it's true, moving is pretty jerky and because of the huge overall weight the
treads will broke up .relatively often.
Maybe I'll think about another kind of treads but I'll finish up the other parts
first

Hi Mark
Thanks for your feedback.
Yes, treads are working, but moving is rather bumpy. Because of the construction
of the treads and the huge overall weight they easily broke up.
I'll give my best to make little movies and post it here. First I have to wire
up the whole elecrtic and build a stronger joint for the upper body.

I'm a little suprised that you chose to use just one motor for each tread. The
whole J5 looks pretty heavy and tracks are not the most efficient drive mechanism!
It's an amazing piece of work though. Congratulations!

You might find that spreading the hinge plates wider on the tread shoes will
help. Having them near the centre increases the "twisting" effect if there are
forces near the edge of the shoes. Also, having 3 per shoe instead of 2 may help
- mine don't break apart very often now, mostly only when trying to turn (move
one tread faster than the other).

Perhaps switching to 2x plates instead of 4x for the tread surfaces would help -
this would help to smooth the curve around the wheels, at the cost of almost
doubling the number of hinges you would need to add.
Otherwise, love this MOC. Great follow-through on your initial inspiration.

Hi Stefan,
I've seen bits and pieces of this as you've posted them to Brickshelf, but it's
great the see Johnny in all his glory. I can't wait to see this completed. I
hope that eventually you're able to post movies of him in action.

good idea,I have a lot of hinge plates in my depot. So I will give a try.

Yes the 4x plates are really "stressed" turning around the wheels.
I think the combination of both, smaller plates and re-arangeing the hinge
plates will result in a mutch stronger and more flexibel tread.

Thanks a lot. Since I saw J5 in the movie the first time (and this is many years
ago..) I wanted to build a copy of him.

Thank you for your feedback. I'll try to make some movies and post them.

Congratulations, this is an amazing achievement! I've been seeing "Johnny's"
progress on Brickshelf from time to time. It would be cool to see this one in
person, to get the full effect of the massive scale. I even picked up some good
detailing/greebling ideas from your work.
I noticed some of the black areas are dusty, which will happen if you work on a
MOC for an extended period of time. I've found an ordinary paintbrush works
well for getting dust off--better than washing, and way better than a toothbrush
(I've never tried compressed air).
Great work!

Compressed air can either be expensive (from the little cans) or sometimes has
traces of oil in it from the compressor.
What I have had good luck with are camelhair brushes. If you buy makeup brushes
it is sometimes possible to get rounded camelhair brushes that are almost an
inch across, making for a fast and convenient cleanup of large areas. Then use a
fine paintbrush as Kyle suggests for the corners and crevices.
> Great work!
Seconded. Spotlighted. Someone else did one in black though, didn't they? Or was
that you too?

This is wonderful! Thank you for building the Famous Robot!
One year and a half!? I respect your dedication!

That is a great feeling. Now we can see your completed work and imagine the time
and effort it must have taken you. Congradulations!

Yes Modules! Great Construction and interesting solutions. Nice parts!

Your very welcome, and thank you. Tell us, what was your experience in learning
to build the hands? Very nice how you learned from the pictures and using the
parts to create the movement.
Also, what are your thoughts about the center section? The torso has many
techniques to compose the structure. What was it like for you to build this
section?

They treads area nice design, and yes smaller width (2x) will roll better.
(as already mentioned)

Can I help? What kind of set up are you using? I looked at the pictures.
I know of a few ways that might help.

First I built the hands as a copy from the Jama pics. So I could easily see and
understand how the really works. They bending mechanism was cool but for johnnys
hand it was not enough integrated. During several cycles of desining, trying I
found a way to integrate the bending mechanism.
Maybe I'll try an "extended" version using a "self adapting" mechanism..

I knew, this section has to be the stronges of the whole model. I tryed to build
a strong center construction and using a kind of "shelf" to construct the outer
shape.
To keep the shoulder section always in horizintal position the section hast to
be a parallelogram.

I think I have to order about 100 plates 2 x 12 from bricklink.. :-) because
treads are 125 studs long, each.

Instead of actuating the rotation point I think about to build a strong
"electric piston". The pisten will then be connected diagonally withn the torso
like this:
HHHHH
I
o----o
I\ I
I \ I
I \ I
X----o
B
B
B
If the piston will change its length, the parallelogram will move. At the point
"X" there will be the connection to the lower body ("B").
So the challange is to construct a compact but (very) strong elecric piston..
At the moment I don't see an other way.. (this is like they did it also in the
real J5 construction)

I think so. My first prototype modules have been build using black bricks
because I did not own enough greys. Then I detected Bricklink.. :-)
