Electronics / Re: Robot camera: stream to control pc and a server
« Last post by anvoice on October 08, 2015, 10:27:17 AM »
Thanks for the suggestion. Upon looking at these cameras I'm not sure this applies to my particular application since I'd like the robot to have access to the data for computer vision, as well as the server. From what I can see it's usually just for sending the video for remote viewing, can't find anything about several streams.

The convenient thing about the IP cameras is the availability of several streams, so they can record wired to a pc and wireless to a server. The small selection is what seems to be less convenient.

The other option is to have a primary camera for the robot, and a secondary FPV-type for the server. Only problem is I would like to install 2 identical cameras for stereo view, and it would be best if they can both send data to the robot and server.
So I am building a Hexapod and want to use SG90 servos. They are rated up to 1.8 kg/cm but if possible I want to keep it under 1.5 kg/cm.
I would like to know how to calculate the torque of each servo at a time.
Here is a diagram of my design, assume that 3 (2&1) out of 6 legs are in contact with the ground at a time and assume for simplicity that the total weight is 10N - I am not sure what the final weight will be yet
Each leg has 2DoF, and therefore 2 servos as shown in the diagram below

I think it is just a two axis joint, only very expensive!

 ;) Hello!
The hip joint must be a secret, because I have tried to find out myself!  :'(
I know that it is very expensive. I think the power supply on the back, is for
counterweight to help balance the body throughout movement.  8)

 ;) Hello!
To get a lot of examples, and forum help, goto They have a lot of items you could use.
they do not specialize in the spider robot particularly, but can give good guidance. Duane Degn is
usually on the forum, and has awesome spider (multiple leg) projects that he has contribute to.
Good Luck!!!  ;) :) :D ;D

Google FPV. This is big with the quadcopter and RC plane crowd, a variety of frequencies.

My main issue here is that it's being potentially sold on as someone else's work. Which is not right at all.

Webbotlib is free software.  That of course might not be what you meant by "sold" but if that's so, a more precise wording should be used.

Mechanics and Construction / Asimo's Hip

(Hello, I am new) Does anyone here recognize what type of hip joint is on Honda's Asimo? It looks like a ball-socket joint of sorts. I also need to know how it works, seeing how the power supply is on the back and not on the legs.

 :) Hello!
I have seen some information on the internet, some company is making for some nursing homes.
The robot gently moves the patients, and does some manual tasks for the physical therapists. I do
not know much they have come along with distribution.  Good Luck!!  ;) :) :D ;D
