If a primary school group is starting out with sequences, loops and debugging, offline teaching materials based around a robot dog, such as RAABE’s lesson unit, may be enough. They won’t control a real robot, though. If a robotics club wants to programme a four-legged robot, suitable programming options and repeatable tasks matter just as much as time for assembly and charging, as well as product documentation that can be checked before purchase.
If you want pupils to learn about sequences, loops and debugging together, you can start with command cards. RAABE’s unit for Years 3 and 4 uses a robot dog as a teaching scenario, without requiring each pupil to have a connected device.
A kit may be a good option for groups that want to programme the movements of a real four-legged robot and eventually go beyond block-based programming. According to Petoi, building the Bittle X and planning how to use its battery are both part of using it in practice.
Before ordering a connected device, check its product labelling and German documentation. If you also plan to use an online learning platform, the Data Protection Conference’s guidance says that the school or school supervisory authority must also have decided whether it can be used.
A good fit if: A primary school group should first practise programming sequences and debugging using cards and group activities. RAABE offers materials for Years 3 and 4.
Limitation: The activities teach programming logic, but not how to control real robot hardware, use its sensors or debug it.
A good fit if: A club wants to work on movement and sensor projects using a real device. Petoi says the Bittle X supports block-based programming as well as Python and C++.
Things to weigh up: Petoi recommends the Bittle X mainly for learners aged 10 and over. For the kit version, the manufacturer says assembly and configuration take 40–90 minutes.
A good fit if: Block-based and Python tasks matter more than a four-legged design. Makeblock describes Codey Rocky as a pre-assembled programmable robot with learning activities.
Limitation: Codey Rocky is an alternative with a robot-pet feel, but it isn’t a four-legged robot dog.
| What you need | What to check before buying | Who should pay particular attention |
|---|---|---|
| Getting started without individual accounts | Check whether the planned activities work without each pupil needing an individual smartphone and account; an app or browser-based tool doesn’t automatically mean you can use it without an account. | If I’m starting by teaching a primary school group about programming sequences, I don’t want to spend a lesson setting up devices and accounts; this straightforward start is a priority for around 29% of consumers. |
| Group activities and debugging | Ask about activities that build on one another, examples of loops and support for debugging during group work. | My group should be able to repeat programmes, spot errors and discuss changes, rather than just trigger set movements; around 29% of consumers focus on this. |
| Assembly and day-to-day use | For the specific version, check assembly time, what charging accessories are included, and how you can store the robot and obtain spare parts. | If several club sessions are scheduled close together, I need a routine that ensures the robot is ready to use on time; predictable day-to-day use is a priority for around 21% of consumers. |
| Documentation and online use | For a connected model, request product identification, CE marking, German instructions with any necessary warnings, and a declaration of conformity. For online learning platforms, check account requirements, data processing and school approval. | Before using a wireless device or online platform at my school, I need to check the product documentation and who is responsible for approving its use; around 21% of consumers put these checks first. |
Preset movements don’t show whether a group can create its own sequences, use loops and investigate errors systematically.
Before buying, look at a complete example project with its learning objective, programming steps and debugging guidance. This will help you decide whether the activities are right for your group.
Without suitable activities, you’ll need to prepare worksheets, activity stations and debugging guides yourself.
For the Bittle X kit, Petoi quotes 40–90 minutes for assembly and configuration, and around an hour of continuous walking per battery charge. These are the manufacturer’s figures for this model, not a guarantee of how long it will last in a lesson.
Choose between the kit and the pre-assembled version carefully, and decide in advance how many devices you’ll use at the same time and how they’ll be charged between groups.
According to Petoi, the Bittle X comes with a Micro-USB cable but no charger, so you’ll need to plan for a suitable power adapter and charging points.
For electrical and connected products, the Federal Network Agency lists CE marking, product identification, German operating instructions with the necessary information, and a declaration of conformity among the points to check. A product description is no substitute for the documentation for the specific model.
Before buying a Wi-Fi or Bluetooth robot dog, request the documentation for that model from the retailer or manufacturer and have it ready for the school’s checks.
If lesson activities or accounts rely on an online learning platform, deciding whether to use it is a separate matter. In its guidance for school lessons, the Data Protection Conference states that the school or school supervisory authority must have decided whether the platform in question can be used.
Before introducing it, check whether accounts are required, which pupil and teacher data will be processed, and who can approve the platform for your school. If you can’t resolve this in time, an activity that works offline or locally can provide a way to get started.
Using an online platform may require consultation with the school leadership, the school authority or the relevant data protection teams.
Petoi offers the Bittle X, a four-legged robot for building and programming projects.
Makeblock offers Codey Rocky, a programmable robot with a robot-pet feel, but it isn’t a four-legged robot dog.
RAABE offers German-language teaching materials that use a robot dog as a scenario for offline coding, rather than providing robot hardware.
Offline materials are enough for an introduction focused on sequences, algorithms and debugging, rather than controlling real hardware. RAABE’s unit for Years 3 and 4 uses a robot dog scenario, with activities on obstacles and loops.
Check the documentation for the specific model before buying it for your school. For electrical and electronic products, the Federal Network Agency lists CE marking, product identification, German instructions with the necessary usage and safety information, and a declaration of conformity among the points to check.
You can’t work out how many teaching groups it will serve from the battery life alone. Petoi quotes around an hour of continuous walking per charge for the Bittle X. Plan around the movements you’ll actually use, charging breaks and, if needed, activities that don’t require the robot.
Before using an online learning platform for school lessons, you’ll need to check that the relevant authority has approved its use. According to the Data Protection Conference’s guidance, teachers may use such a platform only if the school or school supervisory authority has made that decision. You should also check whether an account is required and how the chosen platform processes pupil and teacher data.
