HP-RO INVENT C
Otto Invent Expansion Kit is designed to take the Otto robot to the next level, transforming it into multiple walking mechanisms and imaginative devices. It'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 race. You 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.
The use of any expansion kit requires the Otto Starter kit, which is not included and is sold separately.

Which e-books will you get?
You’ll receive a set of 2 student-friendly e-books, perfect for classrooms, clubs, and curious minds! Developed with leading educators, these guides introduce the HP Otto robot and teach programming fundamentals using Scratch-style blocks.
· HP Robots Otto with Scratch 1 – a modern path to robotics The first volume of this e-book guides teachers through the basics of working with the HP Otto robot. Students learn to program Otto using a block-based editor, create and save projects, control movement, lights and sounds, use sensors and loops, and test and improve their programs. This hands-on approach helps students naturally develop both algorithmic thinking and creativity.
· HP Robots Otto with Scratch 2 – Sensors and Decision-Making in Practice The second volume working with the Otto robot to the next level – students explore how robots sense their environment with ultrasonic sensors and make decisions based on data. Through hands-on activities, they connect coding with the real world: measuring distances, avoiding obstacles, and designing smart features of their own. All in a playful, interactive way.
HP Robots | Otto INTERACT Creator Kit
Discover the Expansion kit EMOTE, which allows Otto the robot to mirror human interactions and reactions and perform a range of emotions.
Give your robot a soul and turn him into an engaging learning companion.
Main Features
- Swap to an OLED screen to display faces, data,
messages, numbers, games, and more
- Color LED matrix for RGB retro pixel graphics, emojis,
mouths, light effects, and scrolling text
- MP3 player with integrated buttons and a switch
for direct control of voice and music files
Seamless Transtion To Advanced Programming
Web based simple programming
No need to download or install anything – just connect
and get started on any desktop operating system.
Control
Take full remote control of the web with customizable
input and output widgets.
Block-based programming
Otto can be programmed using blocks, which is ideal
for beginners, because thanks to the drag-and-drop
system they can immediately see and easily understand
which commands can be combined and which cannot.
Python or C++
More experienced students can write their own code
in different languages to use in other popular platforms
like Thonny IDE and Arduino IDE that will fit best to their
projects and teacher‘s curriculum.
It is simple to switch between.
