Discussion Overview

The discussion revolves around the technical terminology for a device depicted in an attached image, specifically focusing on its description within the context of engineering and robotics. Participants explore various ways to articulate the device's structure and functionality, considering its joints and configuration.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests the term "double-jointed robotic arm with one joint affixed to a mounting surface," but finds it lacking in descriptiveness.
  • Another participant proposes "2DOF manipulator," likening it to a double pendulum configuration with two rotational joints connected in series, suggesting this may help in finding conventional terminology.
  • A different viewpoint argues against using "robotic," stating that the device lacks actuator mechanisms and is merely a collection of joints held together, proposing "a 2D representation of a multi-axis linear assembly" as an alternative, though acknowledging it may not be clear without the illustration.
  • One participant simply recommends the term "double-jointed arm."

Areas of Agreement / Disagreement

Participants express differing opinions on the appropriate terminology, with no consensus reached on a single descriptive term for the device.

Contextual Notes

Some descriptions depend on the visual representation of the device, which may influence the clarity and appropriateness of the proposed terms.

I'm an EE with a fried brain right now, how would you describe the device in the attached picture in technical language?

So far I've called it a "double-jointed robotic arm with one joint affixed to a mounting surface". That sounds really bad and not descriptive.

2DOF manipulator. This is like a double pendulum configuration: two rotational joints connected in series. Maybe that will give some search terms to narrow down the conventional nomenclature.
 
I wouldn't involve the term "robotic" at all, since there are no actuator mechanisms. It's just a bunch of joints held together with sticks.
The best that I can currently think of is "a 2D representation of a multi-axis linear assembly". That, of course, makes no sense whatsoever unless accompanied by the illustration. (Personally, I'd go with the "joints & sticks" explanation... :-p)
 
I'd go with double-jointed arm.
