OZER is a work in progress to develop a totally functional hexapod for exploring functions on unstructured terrains. Keeping as main objectives the development of a low cost, easy to construct, assemble and operate structure which allows the reconfiguring of the platform for new uses.

In this version (V-0.1) the robot is able to perform basic operations such as standing, and walking; the control set is command through SSH connection with a feedback video feed form the Raspberry Pi camera module. Basic sequences for walking and turning are implemented deep in to the Arduino microcontroller to simplify communication between the Raspberry Pi board and the rest of the hardware.

The robot structure is made of 3D printed PLA and ABS on particular printing pattern and orientations ensuring maximum resistance to vibrations, falls, obstacle hits and external forces. The maximum drops test performed was made at a high of 1.5 m with the legs in standing position.
Each leg module contains 1/6 of the total body assembly and its parts are connected using standard sujections parts as 3M screws and bolts.
The hand grip assembly allows the user to grab, transport and deploy the robot easily.
