mecanum wheel robot 3d model

A realistic engineering-grade compact four-wheel omnidirectional robotic car with EXACTLY FOUR MECANUM WHEELS, one at each corner. Rectangular exposed mechanical chassis, overall proportions approximately 200 mm long × 150 mm wide × 100 mm high. Two-level rectangular matte-black metal chassis with flat upper and lower plates, four vertical silver support rods, visible mounting holes, screws, bolts, nuts and washers. Four individual geared DC motors, one connected directly to each wheel, with yellow/gold motor brackets and realistic shafts. FOUR black mecanum wheels with yellow/gold hubs and yellow/gold structural rings. Each wheel has multiple thick black rubber rollers arranged diagonally around the circumference. Use the correct mirrored mecanum roller orientation on opposite sides. Wheels must be clearly recognizable as mecanum wheels, not conventional tires. A compact rectangular black electronics/battery enclosure is mounted centrally on the upper chassis. At the FRONT of the
