planning to build robot for inserting screw into bone

looking for some thing like

H-820 6-Axis Positioner with Controller

Hexapod Platforms and Systems

Parallel-Kinematic Machines of Six Motion Axe

from PI Germany

Is there any other cheaper alternative to start the research

6- Axis Positioner with Controller

COST- EFFICIENT HEXAPOD

Standard- class 6- axis positioning system

Parallel- kinematic design for six degrees of freedom making it significantly more compact and stiff than serialkinematic

systems, higher dynamic range, no moved cables: Higher reliability, reduced friction

Direct drive with brushless DC motors (BLDC)

Indirect measuring principle

Rotary encoder on motor shaft

Powerful digital controller, open software architecture

User- defined, stable pivot point, software- selectable. Positions commanded in Cartesian coordinates. Macro

programming. Open source LabVIEW driver set. Work space simulation software. Optional interface for PLC

control

Fields of Application

Research and industry. For life science, biotechnology, automation, micromachining

* The travel ranges of the individual coordinates (X, Y, Z, θX, θY, θZ) are interdependent. The data for each axis in this table shows its maximum

travel, where all other axes are at their zero positions. If the other linear or rotational coordinates are not zero, the available travel may be less.
