Product Description

Otto Invent Expansion Kit is designed to take the Otto robot to the next level, transforming it into multiple walking mechanisms and imaginative devicesIt's your gateway to endless creative learning and is fully compatible with building bricks.

This kit allows you to create advanced mechanisms to make Otto walk, dance, or roll raceYou can transform Otto from its original biped form into various configurations, including a wheeled robot, a four-legged crawler that moves around, or a tracked vehicle that can go off-road and climb multiple roads and more!

Key Features and Assembly Options

  • Walk and Roll: Otto's signature hybrid build transforms it from a walking robot to a rolling one, teaching students the mechanics behind motion and how different structures impact movement.
  • Offroad Vehicle: Equipped with rubber tracks for superior grip on uneven terrain, this configuration is ideal for exploring rugged surfaces, terrain navigation, and obstacle handling.
  • Mechanical Gripper: Features a fully functional mechanical gripper built with 3D-printed parts and servos, allowing for object manipulation. This helps students explore robotics applications like automation and sorting.
  • Four-legged Crawler: Features four-legged movement, mimicking biological motion and offering insight into animal-inspired robotics.
Group use: Up to 2
