On this film you can easily notice that our construction is base on parallactic mountIt has two axis. The first one is parallel to axis of the earth called declination axis and the second one perpendicular to axis of the earth called hour axis. Besides this construction has additional option. There is possibility of deflection of the cameras.

Concept from the last year
Recent design that is just under construction
•The picture preserves proportion of the real models
•We managed to decrease the size of the biggest wheel by half of size
(idea from J. Grygorczuk)
Deflection of the camerasDeflection of the cameras
Deflection to outside – old idea
Deflection to inside – new idea given by J.Grygorczuk
First we have changed the mechanism of deflecting cameras. Now the turn inside instead of outside. But overall field of view of the cameras remains the same.
290 mm
(in old concept was 175 mm)
The next important change was to move the cameras outside of the wheel. Unfortunately it caused the centre of mass to move out of the geometrical centre of the construction but fortunately we reduced the size by one half to 400mm

The harmonic Drive is generally made up of just three components: wave generator, a flexipline and a circular spline

•The finish of the first robotic telescope is planning on August
•Production of all other robotic end send in Canaries Island is planning on October
