Cardbriks Wall · by Junkbot

A full Robotics & AI lab, on one wall. Made of cardboard.

Students pick a template, pick their electronics, and build a working robot in one lesson. The wall holds the templates, the modules and the workbench. Nothing to lose, nothing to sort, and no bin of plastic bricks.

How the wall works

Three stations. Choose, pick, build, play.

The wall replaces the storage room, the parts drawers and the instruction binders. Every lesson starts at station 1 and ends with a robot on the bench.

The Cardbriks Wall: a cardboard wall with three stations - select template, select electronics, build your project - and a workbench with stools
1

Select template

Die-cut cardboard templates for robot pets, smart vehicles, animals, gadgets, dancing bots, space explorers, crawler bots and walking dinos. Each one has a QR code to its illustrated guide on build.cardbriks.com, so students start without waiting for the teacher.

Select electronics

Colour-coded plug-and-play modules on the board, with spares in the bins below. The modules are the only durable parts on the wall, and they come back to the wall after every lesson to be used again by the next class.

Build your project

A pegboard with scissors, cutters and markers, a cutting mat and two stools. Students ideate, build, test and improve at the bench, then code the brain with the Junkbot Core app when they are ready for the next step.

Templates & projects

60 projects, KG to Grade 12, every one tied to a UN Sustainable Development Goal.

Five kits, one per grade band, 12 projects each. Start with cardboard only, then add the electronics kit when the class is ready for sensors, motors and LEDs. The same projects stock the wall's template station.

For schools

Everything a STEM lead needs to say yes.

One wall serves a whole school. It is delivered installed, with a curriculum mapped to your framework, your teachers trained, and a termly refill of templates. It fits a corridor, a library corner or a classroom back wall.

What is in the programme

  • The wall, installed. Three stations, workbench, stools and signage, built on site in one day.
  • Electronics for a class. Brain, sound, motor, sensor, light and connector modules sized for 30 students working in pairs, plus spares.
  • Templates for the year. A starter library of die-cut projects, refilled each term, graded for Years 3 to 9.
  • Curriculum and lesson plans. 36 lessons across the year, mapped to STEM/STEAM, Design & Technology and 21st Century Skills frameworks, with assessment rubrics.
  • Teacher training. A half-day onboarding at your school, then a termly refresher, with a teacher guide and a WhatsApp support line.
  • The digital pathway. Start analog, go digital: the same templates take the Junkbot Core Kit for sensors, motors, AI and automation, and the Junkbot app for block coding.
  • Competition route. Wall projects feed straight into the Junkbot League and the MissionX AI League, so the wall doubles as your competition training ground.

Where it fits

Footprint 3.6 m wide × 2.4 m high × 0.6 m deep, flat against a wall

Why heads pick the wall over plastic kits

Plastic brick kits Cardbriks Wall
Lost pieces Every set loses parts; a missing piece stops the build Templates are consumable; modules are counted back on the board
Storage A cupboard of boxes and sorting trays The wall is the storage
Creativity Follow the manual, build the model on the box Cut, shape and decorate; no two robots match
Setup per lesson 15 to 20 minutes to hand out and collect Students self-serve from the stations
Growing with students Buy a new kit for each level Same modules, harder templates, then the Core Kit and AI
Sustainability story Hundreds of ABS parts per set, hard to recycle Cardboard that goes in the paper bin; modules reused for years

How schools get started

See it

Bring a class to Do It Lab or we bring a pop-up wall to you. Students build; your STEM lead watches a real lesson, not a slide deck.

Pilot a term

One wall, one year group, one term. We train the teachers, run the first lesson with you, and share student work and rubric results at the end.

Roll out

Extend to more year groups, add the Core Kit pathway, and enter a team in the Junkbot League. Procurement documents, KHDA/ADEK-ready curriculum maps and safety sheets are included.

For events

Put a Cardbriks Wall in your event.

The wall is a crowd magnet: visitors see a cardboard robot moving within minutes and want to build their own. We bring the wall, the facilitators and the templates. You get a hands-on zone that runs itself and leaves no plastic behind.

Pop-up Wall

One wall, two facilitators, a steady flow of visitors. Each build takes 15 to 20 minutes and every visitor leaves with their robot.

Best for school STEM weeks, open days, parents' evenings

Throughput 60 to 80 builds per 4-hour slot

Space 4 m × 4 m, one power socket

Festival Wall

Two to three walls side by side with a themed template set for the event, branded header panels, and a showcase shelf for finished robots.

Best for book fairs, science festivals, mall activations, expos

Throughput 200+ builds per day, multi-day

Extras co-branded templates, human-vs-robot challenge course

Build Challenge

A timed team challenge run on the wall: teams of four pick a template, add sensors and motors, and compete on a course. Judged live, with prizes.

Best for corporate CSR days, inter-school competitions, government youth programmes

Format 90-minute heats, 8 to 12 teams per heat

Impact research

How much plastic does a school avoid?

We looked at what a typical plastic robotics kit is made of, what it costs the climate, and what happens to it at end of life. Then we compared it with a cardboard template plus reusable modules. The numbers below drive the calculator.

2.1 kgBoxed weight of a leading classroom robotics kit, with about 520 moulded ABS pieces for two students.Brickfact listing, LEGO Education 45678
6.93kg CO₂e emitted per kg of ABS plastic produced. Corrugated board: 0.49 kg CO₂e per kg, 14× less.Carbonfact material database; FEFCO 2021 LCA
9%of plastic waste worldwide is actually recycled. 22% is mismanaged and leaks into the environment.OECD Global Plastics Outlook 2022
75%of paper and board consumed in Europe was recycled in 2024. Cardboard templates go in the school paper bin.European Paper Recycling Council, 2025

Climate cost of one student's robotics kit, per year

Plastic brick kit1.73 kg CO₂e
Cardbriks (board + share of modules)0.64 kg CO₂e

Model: a plastic kit shared by two students carries about 1.5 kg of ABS parts (excluding hub, motors and packaging) and is replaced on a three-year cycle, so 0.25 kg of new ABS per student per year, of which 91% is never recycled. Cardbriks: 0.6 kg of corrugated templates per student per year, plus a share of a module set that stays in use for five years (counted as 0.05 kg of ABS-equivalent per student per year). Figures are estimates to be refined with a full life-cycle assessment.

Impact certificate

Every school gets its impact on paper. Cardboard, naturally.

At the end of each academic year, Cardbriks issues a numbered Impact Certificate to every partner school, computed from the number of students who built on the wall. Schools use it in inspection evidence, sustainability reports, parent newsletters and award submissions.

Sample Cardbriks Impact Certificate for a 300-student school: 225 kg of plastic avoided, 982 kg CO2e, Grove School tier
Sample: a 300-student school over three years. A4 landscape, printed on recycled board.
