Serial vs parallel kinematics

Where can I find a list of the (dis)advantages of serial and parallel kinematics?

????

Even though it's not, what is unclear on the question I asked??

OK,

Serial vs parallel mechnical systems ???

I guess I missed the point all together.

Google did find one referance to "serial mechanical systems" and a bunch of "parallel mechanical systems".

So, I missed it, what are you talking about ???

Here are some generalizations.

Serial systems:

- maximize the range of motion for a given number of joints

- have easily-derived kinematic equations

- are easily controlled

Parallel systems:

- are stiffer and more precise

- have hard-to-derive kinematic equations

Most information on such topics cannot be found on the internet. Try your local university's engineering library for books and journal articles. Stuff like the International Journal of Robotics Research (the current sample issue at

even touches on these issues). The IEEE also has some robotics conferences and journals that may be of interest.

I wondered myself, and look what I found through Google:

Additionally, parallel systems are a good deal more expensive.

But their stability is so much greater than that of serial systems that for some apps it makes sense.

Thank you very much for answers, I am working in the field of robotics for years, so I know the standard issues quite well. Infact I searched for some articles summarizing this topic. Tsai or Merlet are dealing with the topic, but it's not the goal of their books.

thanks Pierre

Hi Donald THE book "Parallel Robots" from JP Merlet might help ...

Not exactly true:

serial: easy direct kinematics, difficult inverse kinematics parallel:easy inverse, difficult direct

Not true, see:

Additionally, parallel systems are a good deal more expensive.

That's hard to state because you are comparing 2 very different systems. Like comparing a car and a motor bike. Same league but very different performances

But their stability is so much greater than that of serial systems that for some apps it makes sense.

Sure but nowadays these niche markets are numerous: flight simulator, telescope, vibration, very fast packaging, precise positionning and so on...
