Vision Sensor - Spherical or Revolute Joint

[DannyYeong]

Hi,

I'm currently learning from a tutorial on vision servoing. The vision sensor will move based on its detection on a certain blob. A Yaw and Pitch revolute joint was used to tilt the sensor. But what if I choose to use a spherical joint?Since it covers all sections of an area sweep.

Regards,
Danny

Hello Danny,

you can of course also use a spherical joint, but be aware that you can't control your spherical joint dynamically (i.e. it will act as a non-actuated joint).
But in the end, using two revolute joints, as is done in reality, is probably the better option.

Cheers

I see, ok then I'll use revoluting roll and pitch instead. Thanks!
