Little explorers, ages 5–9.
Kids tap picture blocks (Forward, Turn, Arm), press Go and watch a robot drive to a goal. Four worlds, five challenges each, getting a little harder every time.
What they practise
- Putting steps in order: the heart of programming
- Estimating distance in centimetres and turning in 45° and 90° steps
- Finding and fixing mistakes ("So close: 12 cm short")
- Doing it in fewer blocks to earn more stars
How to help
- Start with Sunny Farm, the easiest world
- Ten to fifteen minutes is plenty
- Ask "what will the robot do?" before they press Go
- Stars are saved on this device only. There is nothing to sign up for
In the classroom.
No logins, no student data: open the link and go. Works on school Chromebooks.
Younger classes (K–3)
- Junior worlds: one shared screen, kids call out the next block
- Each challenge says how many blocks to aim for
- Hints are one tap away
Older classes (4–8)
- The full lab: Word Blocks or Python on a 3D field
- Every run shows the robot's path, so kids can debug by watching
- Save and load program files from the device
FIRST LEGO League teams, ages 9–14.
The 2026–27 BIOGLOW table in 3D, with every mission model and the SPIKE Prime Advanced Driving Base.
Open Training Camp: the same skills on a practice mat, in the same block wording. Kids rebuild each program from the app, press Run, and see "Done ✓" when the robot gets it right.
- Driving around: drive to a line, there and back, turn a corner, drive a square
- Playing with objects: lift the arm, carry it to the drop zone
- Reacting to lines: stop on black, follow a line
Plan and code
- See each mission's position, height and points
- Code in Word Blocks or Python with SPIKE-style commands
- Watch the run on the field with a trail and timeline
- Measure distances on the mat
Good to know
- Opening and exporting SPIKE .llsp3 files is still being checked against the real SPIKE app
- Motion is simple kinematics; real robots drift, so test at the table
The Attachment workshop has five attachments in 3D, part by part: the gear ratio as the motor turns ("motor 90° → arm 30°"), an exploded build order, and a check against the 305 mm height limit, reach and sweep clearance.
