Most of the information can be found on the project website since there is lots of content posted there for everyone to see. I will try to add some info here as the project progresses.
One of the features that makes OSRC unique is its gimbals assembly. Since from day one, the idea behind OSRC was to create an advanced platform in every possible way, we have taken the time and designed a completely unique assembly for the most important part of the control.
The first thing to notice about the design is that both X and Y axises are supported by 4 steel ball bearings, suspending the entire motion in complete freedom and smooth operation. All of the moving parts are being touched by nothing but the bearings since the motion is being recorder by Optical encoders which read the position in increments less than 0.1mm.
The Optical Encoder technology we selected for the movement fits ideally the OSRC design as it in no way interferes while moving the stick in any direction, while providing accurate measurements every time. At the same time, since there is no friction or any sort of contact while moving the sticks, there is also almost no wear on the assembly and minimal chance of damage over time. The same technology is used in advanced robotic projects where every increment of motion is important for achieving a perfect result.
To achieve motion on each axis with the same effectiveness and flexibility, we use a completely new technique. Inside each axis of the assembly there are only 2 parts as thick as 1.6mm which produce a motion if tuned to the correct frequency. To understand this better imagine that there is a disk filled with electrically stimulated components which contract if a current is applied to them. Combined in a circle they produce a moving wave that pulls whatever comes in contact with it. This technique take up less than a centimeter of space and can produce as well as simulate motion like a Ratchet effect of the stick as well as Spring response without actually having any one of them installed.
To visualize the internal assembly better and understand what actually is going on inside each stick, take a look at the drawing on your left, which represents internal workings of the design. As you can see, the design is quite simple and yet very...Read more »
