I would like to get some information to build an arm that will do the following
Pick up an empty plastic bottle that is standing upright. Weight to be from 20 grams to 200 grams. I would like to pick
it up by the neck area. Move it 90 degrees ,flip it to the horizontal position, then rotate it 360 degrees. After that return it to the upright position and rotate it another 90 degrees and release. I plan on using a plc to control the movement . My main question is what would be the most economical way to create the movements ( speed needs to be controlled) Would the large servo be able to handle that weight? What would I need to do this ie gripper type , servo type ,controller for servo or stepper. Stepper size if I go that root etc…
Any incite to this would be appreciated
It sounds like you only need an arm with two degrees of freedom and a gripper, correct? This will significantly reduce the complexity of the setup.
However, if this is for a manufacturing application, how long will the arm need to run? Note that most hobby actuators have a very low duty cycle.
Ya wasn’t sure if this was the correct area . it will be used for a manufacturing application and need to do a complete cycle at 10 seconds min for the lightest bottle. it would run 24 hrs for a week at a time. Didn’t want to get into heavy duty robotics. Wanted a DIY type system that I could customize and low cost for first trial
Most industrial processes / machinery minimize the number of different motors / actuators and take advantage of fixed motion to use mechanisms. For example, you could likely use a number of gears and mechanical systems to do everything you want and use only one motor; the system however would be fixed and able to accomplish that task with those specifications, and very little else. For a proof of concept, you might try using the Lynxmotion Servo Erector Set building system:

If we understand correctly you essentially need one motor to rotate the object, another to flip it, and a third to operate the gripper. Correct? There is no need for additional degrees of freedom.
