The classic wooden Walking Triceratops, originally released in 1993, has undergone a makeover. The formerly used metal gearbox and parts are changed to the assembled plastic gearbox (featuring built-in motor with cables) and plastic parts for safe and ease of assembly. Transparent plastics offer visibility of mechanisms.• Length: 284mm, width: 92mm, height: 115mm (approximate dimensions). Weight: approximately 210g (including battery).• One separately sold AA battery is required. Continuous running time: about four hours.• The assembled plastic gearbox has only two cables, which eliminates the difficult assembly of the power unit.• Gear ratio: 280:1.• Speed: about 1.67 cm/s. (The model moves 1m in about 60 seconds.)• The body is redesigned based upon in-depth research at the Fukui Prefectural Dinosaur Museum.• The body made of wood allows easy modifications and decoration with paint and pens.• Materials: transparent plastic and wood (poplar-type).• The model slowly moves forward swinging its head and tail from side to side, which gives it a more realistic look.• The link mechanism moves forelegs and head, weight transfer moves the tail, and link and crank mechanism rotation moves hind legs.• Challenge level: 2 (5 is the highest.). Approximate assembly time : 90 - 120 minutes.
