Building HUNO

I am eager to get a HUNO built and running for the UK Robo-One this Saturday (tomorrow) , Limor had one rushed to me from Singapore.

Image

I familiarized my self with the build and parts yesterday evening and intend to start (and finish) the build today, posting my notes/observation as I go.
I do not intend to give full build instructions as the build instruction (written and video) seem of a high quality.

The parts; especially the wCK's look solid and well up to the job. They also looked larger than I expected....for some reason I was expecting a smaller robot?

I a certain that the hour build time printed on the box is a little optimistic, simply due to the number of screws (153), ie even if only 120 are used ....30 seconds per screw?

Image

As you can see, in the box all the parts are grouped in assorted plastics bags, which meant some of the larger parts had rubbed/scuffed on others, but nothing serious..the sort of fine scuff marks it might get while being used for 10 mins or so.

Flicking through the manual reveals high quality colour illustrations but 98% of the text is in Korean. I thought this would be a problem, however the CD also include contained both English and Japanese version :)

I had better get building then.

... next installment soon...

So a few hours on and the only thing to report was the diagrams showing setting of the connecting angles are not always very clear....but the video does in most cases show this angle properly.
Also the joint parts have small brass captive nuts...be careful you put them the right way round, they are shown dotted in the instruction.
But construction has gone well, see:

Leg servos (ID2,3,7,8 ) are wCK-1111K ie higher torque

Completed !
Image

(I haven't touched the software yet!) It runs straight away off the remote. Ace!
It seems stable... and needed no zeroing! wow!
I love the bus wiring its so neat. the spare bus connections at the ends of the limbs will be excellent for expansion...
No additional PSU is needed, so save the battery while programming it will run from the mains PSU that it charges off. 12v 5A
There seems to be space in the head and chest for lots of extras.
Wonder why it has aluminium soles, the feet seem stiff enough? Better friction?


WARNING DO NOT UNDER ANY CIRCUMSTANCES USE LOCTITE OR ANY BENZENE OR ALCHOHOL CONTAINING CHEMICAL THAT MAY COME INTO CONTACT WITH THE PLASTICS

The solvent (alcohol benzene) warning is on page 5 of the manual
I didn't think, so as a RoboNova user I put Loctite on a lot of the nuts, some has gotten onto the plastics and they are breaking up already...part of the torso and the left hand has split. I'm hoping the wCK plastic is different if I'm lucky?
:cry: Oh well, I guess I learned the hard way again....story of my life :oops:

The only major fault item was with the robot builder not robobuilder

Sorry to hear about the Loctite. Might you try nail varnish or white glue as an alternative ?

Can we see the new kid on the block next to the RoboNova to get a good idea of the size ? ... Setting our knockout punch height for tomorrow !

Build time 1 hour, finding M2 screws in carpet Timeless

I wish i had use white PVA glue this morning :cry:

Very true.
I am very happy with the speed of the build...if you prepare ie lay out all your parts sorted first, make sure you can understand the joint angle diagrams, I have no doubt that construction first time can be achieved in less that 2 hours The trained guy in the video does it in 55mins . NB spare joints and screws .. for Dino or Dogy

So far I would recommend Robobuilder to those considering buying.....
Thanks again Limor and Pedro...sorry I let you down on the quality build side.

I'll look at Motion Builder and Action Builder software on Sunday(....Must get RN ready now.)

Setting our knockout punch height for tomorrow !


WHAT :!: you would punch a sick one day old robot...?

I've just been testing the stock moves.. wait till you see the recovery moves from falling over 8)

Action Builder 1.01(AB):for some reason I can't get my version to communicate with the robot..? ( Edited 16-7-08 the comms problem turned out to be a problem with my old laptop. There is no problem with Action Builder comms!)
Motion Builder 1.0 (MB):
The comms works fine., but I don't have the hang of using MB after one day.. .. Its so different to RoboNova. ie RB uses the animation analogy controlling frames and transitions times from start to end position.
It calls Scenes what I would call poses, and instead of inserting those poses into the high level language directly you must sequence/build the scenes into a motion/action. These motions must be contained in a project, ...but you can download them individually to be executed by the remote or export them in header file format:?
I like the config feature (missing with RN) but essential with a kit like this. Config enables adding and removing servos .

Until I have gotten used to this method of programming I reserve judgment whether its for me.

Because of the injuries I inflicted while building...his hands would have both broken..if he had punched with them..also he was not really in the same weight class as the other robots so i did not enter him into the fighting event. (In fact latter in the day his right hand did break)
I supect due to his low centre of gravity, his walking seems faster or at least more reliable than RoboNova so I entered him in the sprint...However BillB's Bioloid moves very fast sideways :lol: so RB came second.
(NB Bren mentioned that officially his feet are too long in proportion to his legs...so he did not really qualify as a robo-one bot)

BillB is a RoboSavvy member, as far as I know he does not have a website.

Wow, love the look of this kit. I really want to get one of these!! I'm really sorry to ask but how tall is the robobuilder??? i dont know ho big robonova is for comparison.
Sorry.
Also it runs straight off the remote? what is pre programmed into it?
I have had experience with the bioloid and am really really intrested in this, Eagerly awaiting your review of the bots software, how to program,capture its moves!
Might have to sell lots of stuff to get the funds and purcahse this real soon!!

[quote]....but how tall is the robobuilder??? [/quote]

Robobuilder Huno is 285(H) x 170(W) x 105(D) and mass= 1.25Kg

[quote]what is pre programmed into it?[/quote]

Step forward, back, left, right
Turn right, left (slide without hip mod)
Punch out left,right
Stand up backwards, forwards (also forward and backwards roll)

Plus three stock moves ( you must download to the controller your self)sit, high kick, wave

Lots of moves can be downloaded from the Korean Robobuilder web site...but for some reason I have been unable to do this???

Cool stuff. A worthy kit to purchase by the look of it!!
I really think i might purchase this kit. You can remote contorl it, which is great!!!! can you change the remote buttons to do different things?
How fast are the servos in responding and moving, could you make a potential robo one bot out of the kit?
I want a robot kit that can be expanded at a later date, by the sounds f it this one can be. Also i want to be able to control it remotely and get some really good walking gaits etc from it too!

With a few mods to the joint couplings...ie a small tapped metal plates instead of m2 nuts, and the higher power servos...(discussed with i-bot and Sonic...details to follow).I think the answer is yes.

can you change the remote buttons to do different things?


The moves you download can be activaed on the remote keys 0-9 and *0-*9 (ie 20 moves max). If you are can program in C you can reprogram the arrow keys to perform moves other than stock moves....but I don't know how yet....

Also i want to be able to control it remotely and get some really good walking gaits etc from it too!


If you want open loop control gaits...no problem...If you are talking about closed-loop remote control you need to used C and bluetooth.....

How fast are the servos in responding and moving

The are proper adjustable PID controller servos...see the wCK manual

hi dave

robobuilder has just announced they will be releasing a metal brackets kit for huno.
The kit is intended to make the robot more robust, to participate in competitions, etc.

the details are here: http://robosavvy.com/forum/viewtopic.php?p=16633#16633
