In the paper, in order to abandon traditional measurement method, alleviate damage to projectile and, improve measuring efficiency, basic principle and calculation formulae for measuring centroidal deviation of projectiles were described, and the roll driving parts and the leveling parts of automatic measuring device were designed and calculated in detail, and driving projectile movement by using the principle of friction drive and the encoder to realize precise rotation of 90°for projectile was put forward, and the measurement of reducing errors were introduced. The given experimental results show that system can satisfy the requirement for measuring centroidal deviation with high accuracy. The equipment has wide measuring range and is easy to operate, which is especially suitable to measuring regular projectiles' centroidal deviation.
