Hi all
I'm new to the forum e new to robotics too, I'm interested in buy some dynamixel to develop a project but I've some dubts about powering it.
I wanna to use either rx64 and 28 anda I wan to power them 18v to the 64 and 16 to the 28 but there is the problem:
can I select the using power from the servo (Theres a functions if I remenber well) using the same power board (smps2) so power the board with the 18v and selct 16v with the servo function of the rx28?
or I 've to power them with to power line one 18v and one 16 v and two board (smps2)?
or again I've to use one board for every servo?
There someone that know where to see a draw/diagrams/picture of a mixed servo system powering?
sorry for my english and thank for the reply byez
Hello,
When I found out about these blogs I wanted to make one for myself so I made one.
It's about huamoid robots and what I do with my robots. http://jackshumanoidblog.blogspot.com/
I know several of you are interested in building an autonomous or semi-autonomous Mech for the upcoming RoboGames in April.
I am starting this thread to have a place for discussions about challenges/ideas/solutions in and around the problem of how to build an autonomous robot that can compete.
I do not have a name yet but plan to enter a fully autonomous biped mech using a Lynxmotion BRAT.
Here is a youtube link to a Lynxmotion Rover that I put a CMUcam2+ head on that does color tracking. That work is the basis for the auto targeting system that I am developing for the competition.
Finally got to do some work on my robot. Making it after the battletech mech Zeus. Making using a papermech I found, thing looks real cool. Using HSR-5980sg's for servos. Some Lynxmotion parts for joints. Using servocity chain and sprockets to add some power. Bigbluesaw is cuting out some pieces for me. Will add pics as I make progress.
Had to scrap my first try, the mech(riffleman) was way to heavy.
Included is a QCAD pic of my bot and a pic of the papermech.
Hi all,
I am new here and this is my first post. I blew the fuse on my bioloid kit and I think it was because I downloaded the Behavior Control Program before the Motion data. I went to RadioShack to get a new fuse but could not find the correct one, which is a fast-blowing, 5A, 250V fuse (the label on the fuse says F5L 250V.). Would a fast-blowing, 3A, 250V fuse work ok? Or maybe a time-delay, 5A, 250V fuse?
Besides updating and improving the phoenix code I’m also working on Terrain adaption. I’ve already posted some test setups about the sensors using the phoenix. The FSR’s in combination with this setup didn’t give me the wanted reliability. Now I’m using some Micro switches to ‘feel’ the ground.
I thought I share the progress made by showing the vids.
Although you haven’t seen me a lot around on the forum lately I do have been active on the background. I did some major changes in the Phoenix code. Since the changes where so big the version number is upgraded to 2.0 this time.
I uploaded a new video showing the new (and some existing) features in V2.0.
Sorry for the long video. Did had some good time with a video editing program though. :P
The major changes in 2.0 are fixed point calculations to lower the cycle time.
Separate files to easy change remotes or hexapod settings. This will allow the user to simply add the correct remote file and hexapod file to adapt the code for different hardware without having... [Read More]
I wan't to discuss the importance of the mini itx, nano itx, pico itx, netbook etc integrated grafic processor for the robots task like , target tracking and pointing and navigation and more difficult face recognitions
Webcams or tv camera?
How much resolution its needed ?
Its frame rates important?
Which grafic processor its better gforce (ion) or intel 945, or..?
How much dedicated memory?
I know maybe its such a large amount of asking...eheh sorry

My name is Charles Whitaker and I'm currently working on my 11th grade engineering project. For this I decided to create a Oceanic Sunfish (Mola mola) type blimp:
So i was searching the nets looking around for a place where i could consult people to help me with my first ever robotic project. I have a little experience with arduino and a decent amount of experience with electronics.
So, i have this idea for my year 12 design & technology project. I would like to build a rover that has a camera with 360degrees rotation. basically pan and tilt. It also has to have a microphone and loudspeaker so i can talk and hear through it. Now the thing is i waant it to have about a range of about 200 - 300m maybe 150 through walls and building and such.
What im asking is how would i go about building something like this? and if you think it's possible?
My thoughts have it kind of like the SUGV, if any of you have seen it, it has the rolling strip thingys for wheels like tanks, i was thinking that or just 4 wheels. and the camera can just be mounted on top, able to rotate and tilt up and down, not... [Read More]
i was trying to figure out the best drive system setup. as of now this is how i have planned. i will have 2 stationary shafts acting like front axle and back axle, then on each side of the axles i will have dual roller chain idler sprockets, one chain will go down to the tire, and another will go to the motor positioned in the middle of the bot, this said, that means the motors will have 2 sprockets on them, one to go to the rear axle sprocket and the other to the front, then the wheels will have their own drive system with a set of pillow block bearings, axle, and sprocket.
if you were keeping track, that's a total of 16 sprockets for the bots drive system!, i don't know where you get your sprockets... [Read More]
recently we will find a lot of netpc like asus 901 or acer 110 that will soddisfy a lot of the requirements for a pc based robot on ebay at low cost
why spend more for only the MB?
buy a complete system tha include a nano or mini itx MB (like via one) add the ram , the psu, the hd/ssd will cost more than buy a complete atom 1.6 based netbook tha include also a lcd the keybord the speakers , a wifi module, a card reader bluetooth etcetc
the reason that I can see are these:
weight: these netbook weight nearly a kg but they are strippeble, you can run it trought the main robot battery you can disassembly the lcd the keybord and the chassis I don't think it will weight more than a nano/mini system
dimension: the mini itx format is 17x17 most of the netpcs are 24x17 but like before you can strip it
power draw?: I don't know will a netpc without lcd draw more than a nano/miniitx system?
Introducing my newest creation: the Creeper2! I started designing the Creeper2 Oct. 1 as a short-term Halloween stunt and long term upgrade of my previous Creeper robot (http://forums.trossenrobotics.com/al...&pictureid=197). It’s been a whirlwind month, however I not only built but programmed the robot in the last 3 weeks.
As you can see in the above video, the Creeper2 is an ideal seasonal solution to candy dispersal. It will be serving candy to boys and girls who stop by its “lair” this Halloween,... [Read More]
