The purpose of the transport system (TS) is to transport a load from one place to another and then return to its original position using no external power. It comprises a self-propelled trolley powered by the potential energy of the load placed on it. It operates by purely mechanical means. The trolley runs on a wheel in a track on the floor. It is about the size of a hospital trolley and will carry a load of approximately 8 kg. Short distances indoors will be covered initially - up to around 8 metres. The design of the TS system is described here. Dimensions are available for an initial prototype model.
The concept on which the system is based is described. The main components in the system will be described; and how they operate and interconnect. The system enclosure and paneling will be described. The sequence of operations in the transportation process will be outlined. Multiple sketches are provided of components, panels, frames, and the transportation process itself. How the system is operated is described. Design notes, options and the mechanics of the system are given as well. References found useful during the design and the selection of different options are given.

Gemini was able to remember the topic "Transportation System" and use it as background knowledge to answer questions put to it on the mechanical design. To get the best results from the AI system it was necessary to streamline the prompts to quite specific questions. One drawback of this prompting process is that you cannot make the queries too general as Gemini is unable to maintain a broad overview of the system being examined and can only answer quite narrowly focused questions well.
But for specific design queries it was very good and was able to offer multiple alternatives every time.
Then in June 2024 another design iteration was put online. In this iteration the buffer clamps used to fix the dish and compression plate were replaced by pins. This is not a major alteration just replacing clamps with pins, but also showing how the pin carriage assembly is installed and operated.
In July 2024, the next design iteration came into being – the buffer version: this iteration is described in this write-up. Here a buffer plate along with buffer springs were added to ths system. This was to store energy in a buffer (springs) to return the empty trolley to Bay 1 from Bay 2. It is described in the write-up along with diagrams.
A record is kept of notes taken during the design. They show the various options explored. Only some of the options were implemented but the notes are available for comparison purposes and as a record.
