Tachikoma maintain control of their legs while using wheels to drive down a road, and shift their weight around turns. Other abilities of the Tachikoma include jumping great distances, sticking to vertical or inverted surfaces, engaging a thermoptic camouflage mechanism, and grappling/rappelling using their adhesive string launchers. Each wheel appears to be angled and omnidirectional, allowing the Tachikomas to move in any direction with their holonomic drive system. They are apparently street-legal (presuming no legal exemption for Section 9). They can move by walking, or they can drive at high speed by using the wheeled footpads on each of their four legs. They normally operate as independent units and receive orders from human agents, but they can also be directly piloted from a cockpit in their abdomen. Tachikoma are controlled by individual AIs, are capable of speech and generally exhibit a childish, curious, joyful and active personality, although they are consummate professionals in the field. These eyes sometimes become expressive in the typical anime style. Each eye has three pinholes, possibly for triangulation. Three are on the "head" and one is beneath the abdomen. Tachikoma are the size of a small car, and are of a middle-blue colour, with four "eyes" fitted on the surface of their bodies. Tachikoma design differences between SAC and SAC 2nd.

The right-most image is a wire frame of the 3D model the middle image is the Tachikoma model rendered with generic materials and lighting the left-most image is the character as it appears in the series. This method simplified the task of animating detailed robotic characters. Throughout the animated series, Tachikoma characters were rendered by 3D software using a cartoon shader that mimics hand-drawn art.
