Design of high-precision rotating crunch for monitoring camera
111 USD The turn of the PTZ camera is performed with a small error.The defect is usually static, caused by the application of dental transmission in the mechanism.The task:
Develop the most compact platform for unreturn cameras of approximately size: 100x50x50mm.The mechanism of rotation is mainly on servo or step engines that are used in robotics.Examples from China:

Requirements for the Platform
Compact sizes
accuracy of the camera reversal
Stretch to Stretch
Operation on the street, full-time
The camera on the platform has to return.
Whis X - minute -150-150, gelat 360 degrees
Whis Y - minutes -5-5, gelat -15-15 degrees
Root management is desirable in generally accepted protocols, type Hikvision (signal transmission through a pair, POE)
The desired minimum energy density of the rotating system (food is transferred to a distance of 50-100m per rotating pair)
accuracy of turn
Here is X - the maximum possible, with the minimum step, the maximum repetitivity (step 0.9-1.8 - ok)
Yes Y is the maximum accuracy as possible, the step is not important, but better = Yes X
The platform must have a position/compass sensor.
Fixing the platform to the surface
Examples of mechanical
A modular design.
Platform separately.

Напишите более точно какие нужны параметры. Разрабатывал для личных нужд механизм поворота 360 по осям x,y,z. Максимальная точность которую добился 1 градус по любой оси привода FeeTech 360 градусов 7,4 В 35 кг

нам нужна точность поворота 0.1 градус минимум

Шаговые, так шаговые, вопрос бюджета вторичен
-
Бюджет на по данных характеристикам порядка 1000$. Так как проэкт рассчитан не на массовость все шестерни заказывается будут индивидуально в количестве до 100 шт. Если использовать в условиях +-30 то простая печать на 3D принтере не подойдет нужна будет лазерная фрезеровка под заказ. По поводу размеров тоже проблема. Самый точный шаговый двигатель доступный в Украине это точность 0,9 градуса, что бы достичь точности в 0,1 градус как минимум нужна связка передаточных шестерней примерный размер конструкции 300*200*200мм. Точнее сказать не могу нужно составлять чертеж и все просчитать
