Well here are some of the first pics of the whole set of Lynxmotion J5 parts, And quite a few there are.


First layout of parts.


Close up.



Shocks for the torso, bottom right.




Sabre tooth 2 x 5 5amp motor controller.


Damn, That's a lot of parts


Parts laid out ready for assembling.



ER1 in the back ground.


Parts for J5's tracks and base.


Nice challenge here.

Thought i would give you all an update on My Modified J5 Like Tyberius's J5 with some slight mods. Have had it just over two weeks now and the ITX parts should arrive soon from Tyberius. Thanks for all your help in this area Tyberius.


Torso now in progress.


Shoulder sections


Shoulder sections with HR5990 Digital servos.


Torso shock system, These can be altered for more or less compression, either with stronger springs or the type of oil


Shoulder servos.


Starting to take shape, please note that those long alloy rods have changed to 25mm in length, I was just experimenting with longer lengths.


Wrist rotation section.


Hand section complete.


Modded alloy discs for hand rotation system, protrusion filed off.


Filed Alloy disc against nylon gear. As this does not need the protrusion on the alloy disc.


Short 25mm alloy tubes now inserted.


Arm installed.


All sytems on the arms have been tested with my Hitec servo programmer.


Tyberius has made a suggestion that I place the wrist servo and gear at the other end of the alloy wrist to hide the servo at the elbow, this could be a good idea, may change this and have a look at the possibilities.

Tyberius, What sort of weight can these arms/hands pick up?? Do you have some numbers.

07-06-2008, 02:02 PM
Nothing solid, but I applied rubber grips to the inside and picked up a full bottle of guiness with them.

07-06-2008, 02:06 PM
Thanks, That's good enough for me, ha ha.

Nice work and parts!
It's almost like christmas when you get your parts LOL. (I always get that feeling when waiting for an order.;))
Looking forward to follow your J5 project!

Very good pictures.

Thanks, That's good enough for me, ha ha.

The important things in life. Now if it had a gun like Eve's, it could jack liquor stores and carry the beer home.. :eek::eek::eek: :mad: :wink:

Zenta:Many thanks for your comment, And yes, It is like Christmas lots of goodies. I really am enjoying assembling J5 great fun, I have taken over 140 pics so far in the construction stage, So I can see a tutorial coming up as soon as I have finished it, The software side of it may set me back a bit, but I know I can get good help here if I get into trouble and Tyberius has all of it worked out.I'm looking forward to having a go at the eyebrows using some very small servos.
Adrenalynn: I had planned on fitting weapons on the lower arms at the elbow stage and still will do this, but for now I will make it the same as Tyberius's J5 so as to get the whole system working as he has as this will be good for me to see how it all works. There is so much potential with this robot it will keep me out of trouble for some time, with Mech wars as well.

Stoked to see another J5. It was a toss up for me between a hexapod, a J5 or a humanoid. I figured a hexapod would give me the most versatile platform while moving away from a rolling chassis.

What are your plans for the head/sensors and stuff?


07-07-2008, 02:02 PM
darkback2: Thanks for your comment, At this stage i will try to build it the same as Tyberius's J5 with a couple of mods like having eyebrow servos [miniture] and just get him going first, Then experiment with other sensors later. Thanks for your interest.

Received my ITX parts today from Tyberius, Thanks Tyb. So looking forward to assembling it, Have a few more construction parts to assemble yet before I get to the nitty gritty stuff.

Awesome man, glad to hear :)

Nothing solid, but I applied rubber grips to the inside and picked up a full bottle of guiness with them.uh huh, yeah I see how it is. You make fun of me lovin' the Fat Tire, but you're drinking Guiness in the US? Haven't you ever talked to any Ireland peeps? They just laugh when they see someone drinking Guiness outside of Ireland.

It may not be Guinness from the UK (which I've had on more than one occassion. Can you say "food group"?), but it's certainly better than the bunny pee that passes for beer around these parts.

(Portland Oatmeal Stout excepted)

The more I see of the J5 kits, the more I'd really like to get one.
But a thousand bucks.. :( Thats way way out of my price range.

07-10-2008, 02:01 PM
It's a great kit, but it is a bit spendy. You still need batteries and a brain to make it work, I have over 3 grand invested in mine... but I sort of went all out.

You do get your money's worth though, its a great platform.

Well, If it's any consolation guys i have spent over 5K on mine NZ $'s and because we live half way around the world freight can be a killer, but I love robots and if I did not spend the $'s here it would be on something else. Tyberius has been great in acquiring some parts for me and at a good price, so this has helped me a lot on this project. And if I decide to also make it autonomous as well then the price will go up further, This bot has a huge potential for experimentation and one that will keep me going for some time, I have so far taken 140 pics of the process which are on my web site to date, When the project is completed to the stage of Tyberius's machine I will post here on TRC tutorial, then as time and upgrades permit will add to that.

A few more updates on my J5.


Alteration of LBA gears and bearing to the elbow end.


Side view of LBA and bearing.


All finished, and looks a lot better.


Note that the wrist rotate servo is tucked under the elbow servo, much neater. Thanks to Tyberius.


note, The arm on the right is the modded version of the wrist joint, the left one has yet to be modded.


Close up of mod.


Side view of modded wrist.


SES carrier for the SCC32 servo controller.


SES carrier and SCC 32 servo controller.


Wrist mods now made, LBA [low profile axis] bearings and gears now below elbow.


ITX computer parts arrived a few days ago from Tyberius [Thanks Tyberius]


Webcams for J5's eyes, speakers to be stripped down, USB 7.1 sound and metal servo discs, these are going to replace the nylon ones that come as standard on most servos,although the HSR5990TG come with metal ones as in photo.


NiMH batteries for J5 8.8v for the ITX and 10 batteries for the 12v motor drive system, these have to be made up.

07-11-2008, 03:51 PM
Wow, I had no idea how many parts there were. Thanks for all the great pics. Some of this stuff should end up in the tutorial section some day for others to learn from.

07-12-2008, 01:33 AM
Hey Matt, I have all photo's up on my web site to date, and keep updating on a regular basis. When all finished I will do a tutorial of about 150-250 photo's. Tyberius has a lot of good idea's and I have a few up my sleeve, One being in the next upload of pics strengthening the rear upper shoulder section to stop movement of the shoulder servos. Also I have an idea on what to do about that Rotation base which is not up to it's job with the amount of gear that it supports. I am going to get machined two alloy plates the same as the LBA joints and spread the ball bearings around the outer edge, This will stop any tilting in all directions.I may also look at gearing the servo motor in the rotation base or put a HSR5990T in it's place, one advantage of these digital servos are the programming of them.

07-12-2008, 01:40 AM
Great work there,and glad its all coming together.and love the mods (well worth while).

07-12-2008, 08:04 AM
nanomole39: Thanks, It's starting to take shape now and all the interesting bits to come. Camera's next.

07-12-2008, 08:17 AM
Hey 4mem8, your upper torso reinforcements look great! Definitely will help stabilize that flex a bit. I've been meaning to do something along those lines but I haven't the time nor tool resources lately.

07-12-2008, 04:33 PM
Thanks Tyberius, just have to sort that rotation base out now, make it more stable and less flexible and then we will have a very stable bot..

Some more updates on J5


This is the head section to which the camera's will be mounted, Also two 15mm x 15mm angle alloy and 1 ACB-01 channel.


Alloy channel bolted to the ACB-01


Two camera's mounted on the alloy, Be carefull here NOT toremove the laquer on the circiut boards when tightening up the 4 screws, otherwise you will get a short through the alloy. There are stand off's between the camera boards and the alloy.


Side view showing mounting of boards.


Bottom view, Note stand off's, These are the waste lexan that are punched out of the sheet SES.


Slots cut in the back of the ACB-01 and rubber grommets for the video cables.


Just to be a bit different on my J5 I have included a neck out of a ASB-18.


Now my J5 is starting to come alive, The neck extention is starting to give him a character.


Close up of head and long C bracket on pan servo. May put a mic in the end cavity for the ears.


M'mmmm Is this what I look like!!


Mouth LEDs have to be added yet.


Full side view, Looking more like a J5.


Leaning forward being nosy.


Lots of cables to tie up.

looking at the camera board and the mounting screws it looks like the bottom right is touching a solder point,might need to check it,when i mount pcb boards always use plastic screws or plastic washer on top and bottom

Robot maker, Noted, and funny enough this was to be addressed with nylon bolts, just have not got around to it. This weekends project as well. Thanks for noting it.

i always use them when i mount boards with nylon spacer and treaded nylon spacers if threaded then bottom of spacer doesnt have to be nylon ,if i need to ground it then a seperate wire to base plate or battery -
keep making your johnny five look good,i just started on mine so it will take awhile to catch up
