I am building a fully functional lifter system with all of the hardware and electronics to allow builders to control the position of the periscope lifter by setting digital signals or sending a serial command via I2C or SPI.
This system is a closed-loop servo that allows the position of the periscope to be set anywhere from 0 to 100%.
For example, this allows the periscope to rise to 50%, pause and move to 100% rotate 360 degrees and then down to 75% and stop. The ability to position the periscope in any position allows for a more lifelike R2 with endless configurations.
This design has a limit switch screw that allows the lower limit switch position to be set by simply turning the screw. This makes it easy to align the positon of the periscope pie panel with the surface of the dome.
This system utilizes a custom-made 3/4” diameter acetyl lead-screw. The large diameter allows the periscope to rise quickly via an aggressive thread pitch, while reducing the friction between the lead-screw and lead-nut, and protects the motor from the static load of the periscope. The lead-screw is hollow to reduce rotational mass. The lead-screw and lead-screw nut prototypes (shown in my photos) are the raw acetyl color (ugly) – the final versions will be BLACK (cool).
The Lifter Kit will include:
Aluminum Top Mounting Plate
Aluminum Bottom Mounting Plate
Aluminum Lifter Carriage
Aluminum Riser Pipe
Acetyl Custom Lead Screw
Acetyl Custom Lead-Screw Nut
Linear Slide Bearings (2)
Top Lead-Screw Bearing
Bottom Lead-Screw Bearing
Lead-Screw Top Bearing Adapter
Bearing Shafts (2)
Support Shafts (2)
Motor Mount
Drive Pulleys (2)
Timing Drive Belt
Top and Bottom Limit Switch
25mm Drive Motor with Hi-Res Quadrature Encoder
Motor Driver and Encoder Control Board with 8 preprogrammed routines (Assembled and Tested)
Miscellaneous Hardware
The target price for the Lifter Mechanical Components, Motor, Encoder, and Controller Electronics is $300 US and $314 International
Rotary System:
In addition to the lifter, I am also providing a rotary system to rotate the periscope to any position. The system will behave like a servo, with a closed-loop positioning capability. The rotary system allows for continuous rotation of the periscope – similar to R2’s dome.
This ability allows for periscope lights to shine on the surrounding walls and or objects and provides a good platform for situational awareness sensors. I really wanted to be able to create a police-like siren.
The rotary system will also include a 6-wire slip ring to allow the periscope lighting kit to function properly.
This Rotary Kit will include:
AlumPeriscope Riser Cap Adapter Mount
Alum Rotary Bearing Housing
Rotary Bearings (2)
Limit Switch
Limit Switch Actuator Ball Bearing
Metal Drive Gears (2)
Alum Gear Bushing Adapter
Alum Motor Mount
6-Wire Slip Ring
25mm Drive Motor with Hi-Res Quadrature Encoder
Motor Driver and Encoder Control Board (Assembled and Tested)
Miscellaneous Hardware
The target price for the Rotary System and All Electronics (Assembled) is $185 US and $190 International.
This is complex run as it comprises the Lifter Mechanical Hardware, the Lifter Electronic Control Board and Control Software, the Rotary Mechanical Hardware, and the Rotary Electronic Control Board and Control Software. In addition the parts in this system are rugged to handle repetitive use. The aluminum periscope and riser are heavy and off-balance. Add to this, the condition of R2 being tipped backwards, and it puts a lot of strain on all of the hardware.
I plan to offer several pre-programmed routines that will control the lifter, rotation, and lighting by setting the appropriate input signals. The two systems (lifter and rotary) will be coordinated to allow each system to calibrate and operate without crashing (too much) into the dome.
I am also planning to offer a Center Lifter Kit that fits in the center of R2’s dome to lift objects from the Center Pie Panel location. The target price for the Center Lifter will be $350-$400 (I will lock this down shortly). It is more expensive because I assume the quantity of interested builders will be a fraction of the Periscope Lifter.
voté pour 1 complet, en réflexion pour un second mais je pense que je préférerai me faire une autre solution et pourquoi pas avec un design commun que l’on pourrait se faire entre constructeurs français So expensive for me… Par contre, si vous pouvez faire des photos de détails lorsque vous l’aurez, je suis preneur…
Tchao,
Mike
voté pour 1 complet aussi. Le tarif de ouf ! Mais c’est THE rolls royce of the lifter. J’ai dit oui, je suis faible 
le run est ouvert 
🙁 )j’ai pris le complet. Merci lolo

1000 euros dans la simple fonctionnalité du périscope, c’est quand même un peu abusé je trouve….
C’est moins de 500 €, mais il manque périscope en lui-même et éventuellement le kit d’éclairage.tu as donc compris d’où viennent les 500 supplémentaires J’ai craqué, j’ai pris l’ensemble. 2 trucs qui me font un peu réfléchir : – la rotation du périscope a intérêt à être bien maitrisée, sinon copeaux de dome et de pie panels à prévoir…
– périscope = dome difficilement démontable (en fonction de la façon dont le pie panel sera démontable), mais surtout le fait que tout l’ensemble lifter + périscope restera de toute façon solidaire de la base plate
donc pour ceux qui transportent R2 démonté, il faut plus ou moins oublier…
je réfléchis tout haut pour me trouver une bonne raison de ne pas céder
