Researchers have developed SPINDER, an open-source 18-degree-of-freedom (DoF) hexapod robot, designed for robotics research. This system integrates hierarchical control based on central pattern generators (CPGs) and an analytical inverse kinematics solution, enabling complex and coordinated movements of its six legs. The open-source design facilitates replication and modification by other research groups, promoting collaboration and advancement in the field of bio-inspired robotics.

SPINDER's control architecture is based on a hierarchical CPG approach, mimicking the neural systems that control rhythmic movement in animals. This allows the robot to generate complex and adaptive gait patterns, crucial for navigating varied terrains. The inclusion of analytical inverse kinematics is a significant advancement, as it provides an efficient and precise way to calculate the joint positions required to achieve a desired leg end-effector position, avoiding slower and computationally intensive iterative methods.

SPINDER's development addresses the need for accessible and configurable robotic platforms for research. Being open-source, SPINDER is expected to serve as a valuable tool for exploring new control strategies, learning algorithms, and mechanical designs in legged robotics. This approach democratizes access to advanced hardware, enabling a greater number of researchers to contribute to the development of robots capable of interacting more dynamically and autonomously with their environment.
