Tank robot kits and tracked chassis buying guide

A buying guide for tracked robot kits and chassis evaluates seven different platforms. These kits range from affordable sixty-dollar Arduino mini tanks to advanced metal Raspberry Pi tanks featuring a 4-DOF arm and a lidar-equipped ROS SLAM platform.

Tracked robots offer advantages over wheeled models by spreading weight over a larger contact patch, allowing them to navigate obstacles like carpet edges, gravel, and small steps. They also utilize skid steering for zero-radius turns. However, the guide notes that tracks increase friction and power consumption, and can make accurate odometry more difficult due to inherent slipping.
