Spherical Parallel Manipulator

A 3D printed prototype of spherical parallel manipulator (SPM) with revolute joints consists of two pyramid-shape platforms, a base and a top mobile platforms, connected by three equally spaced legs each having two curved links. The lower links of SPM are rotated with three Dynamixel MX-106 servomotors fixed to the base platform. A joystick is used to demonstrate the performance of SPM.

Been watching a few of these recently (don't judge me), this is the first one I've seen with the focus 'inside' the mechanics. Not sure how it would be better, or worse, but it's nice to see the negative plane shown some love.

[@azamatyeshmukhametov7380]

Looks great! Unusual architecture of parallel manipulator and controlling by joystick is very impressive. Well done guys!!!

[@seanfan84]

It is in reverse kinematics.

[@BHARGAV_GAJJAR]

Look up project agile eye by prof.gosselin at university of Laval

[@williamchamberlain2263]

I think that I saw a video on that back in 1998

[@AbdallahEzzatKoji]

I like how you simplified the shape of the first arc(s).

[@BspPlays9287]

Very fine controls

[@user-xc7gv4kh9t]

Сложность реализации и управления увеличена, надёжность снижена, против той же платформы с винтовыми толкателями, например. Выглядит прикольно!

[@A3Kr0n]

I'd like to see a spherical parallel manipulator with an additional rhomboid encabulator attached to the gangway.

[@smurp_com]

Why do we see so few encabulators these days?

[@bluesinamajor]

Maybe for self leveling pool tables on cruise ships?

[@user-tc2ky6fg2o]

Thank you!

Normal robotics engineer: Lets design this mechanism to avoid singularities.
This things designer: How many singularities? YES.

[@FA-id4qg]

Interesting 👍

[@walterlippens6675]

Amazing 😲😲😲

[@highlandermachineworks5795]

Seems like a complicated version of the cable positioning system for a side mirror. Or amimatronics.

[@lordclancharlie1325]

Side mirrors move up and down and left to right only and not simultaneously no ? not sure...

[@ewthmatth]

Are there only three actuators in the three base joints? Or do the other joints have actuators too?

[@listerdave1240]

Three actuators only. Equal to the number of degrees of freedom.

Красота!

[@rezamoradi3314]

This is great.
How do i make it
?
How are the sizes and angles obtained?
It's hard to design at Solidworks. Do you have a robot design (STL files )?

[@josephjoseph9620]

Y esto para que es?

[@afshinzeinaddinimeymand4647]

Excuse me. Could you share the inverse and forward kinematics of this robot?

[@ozanozdemir5515]

Interpolation algorithm needs to be improved.. Good work!

[@varietycontent3390]

NASA has commissioned something similar for an RCS booster, but only using two motors and a decently complex compliant mechanism. Not sure the applications of this specific mechanism but I don’t see it making a debut in aerospace at any point, being heavily weight focused. The TH-cam channel Veritasim has a really good video about compliant mechanisms which features the one commissioned by NASA.
