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.
