Electromechanical Designer ROBOTS-XXI

Analyzing the rubble in the garage, I found my old designer with whom I enjoyed playing as a child. This designer began to be produced in 1986, my copy was released in 1990. It was produced in the Latvian SSR by the production association Straume . Apparently it closed in 1992.




These are the details we see removing the cover

The main control panel. can manage back and forth, has 4 contacts, plus or minus input from the battery pack and plus or minus output to the engine. The control unit, the motor and the battery unit are connected by wiring to the terminals, which initially teaches the basics of electrical engineering.



Engine



The battery pack, under two AA-size batteries, is indicated in the instructions as A316, but with a voltage of 4.5 V, where I don’t know what to find now, but I’m not sure about that later.



Next, we turn to mechanics, everything is actually much more interesting here, all the parts are ball-shaped and made of transparent plastic, so the young designer can clearly see how the mechanisms work, in the designer they are presented in three types

Gearbox



Gear shaft



Differential



Blocks are interconnected using hex connectors



The wheels are attached with hubs.



Here is the wheel itself



Unfortunately, one hub was lost, so it’s impossible to assemble something four-wheel, but we have an excellent propeller



and floats



then you can collect something waterfowl.

Now about the sad, as I said, it requires 9 V for power, the engine did not start from two finger batteries, but the problem does not seem to be that, it didn’t work from the crown either. Apparently due to the fact that he spent almost 20 years in an unheated garage, some of the details oxidized and became unusable, so there will be no demonstration of work today, I promise to show everything later when I restore it. Lastly I will leave a few examples from the instructions that can be collected from it.
