TL;DR — the shortest possible answer
- You have a 6–8-year-old, first Lego robot: buy WeDo 2.0 (cheaper, simpler)
- You have an 8–11-year-old, more serious projects: SPIKE Essential (but pricier)
- You have a 12+ kid or harder challenges: neither — look at Lego SPIKE Prime or Mindstorms
- You have a kid already attending a class: probably no need to buy — ask what we use, kids share equipment in lessons
But if you want a more detailed look — read on.
What these sets actually are
Lego WeDo 2.0
- ~280 elements in the set
- 1 small motor + 1 sensor (motion/tilt)
- Bluetooth "Smarthub" for wireless connection
- Visual programming language via tablet or PC
- Ideal age: 7–10 years
- Price: ~16–22,000 RSD
Lego SPIKE Essential
- ~449 elements (significantly more)
- 2 motors + color sensor + distance sensor
- Bluetooth "Hub" with a 5×5 light display
- Visual language (Word Blocks) or Python
- Ideal age: 6–11 years
- Price: ~28–35,000 RSD
Differences table — straight up
| Criterion | WeDo 2.0 | SPIKE Essential |
|---|---|---|
| Price | ~16–22,000 RSD | ~28–35,000 RSD |
| Number of elements | ~280 | ~449 |
| Motors | 1 small | 2 motors |
| Sensors | 1 (motion + tilt) | 2 (color + distance) |
| Hub display | None (just an LED) | 5×5 LED matrix |
| Programming language | WeDo blocks | Word Blocks or Python |
| Battery life | ~3 hours | ~6 hours |
| Lego SPIKE Prime compatibility | No | Yes (parts are the same) |
| Ideal age | 7–10 | 6–11 |
| Project difficulty | Lighter, faster | Richer, more complex |
What a kid can realistically build
With WeDo 2.0
- A small fan that turns on with a sensor
- A robotic frog that jumps when tilted
- A crane with a weight
- A mini remote-control car (via tablet)
- Simple systems: transport, levels, ramps
Typical WeDo project: 30-45 minutes building + 15 minutes programming. Fits in 1 lesson.
With SPIKE Essential
- A vehicle that follows a line
- A robot that "reads" colors and reacts
- Two motors enable real movement (a car with differential)
- A mini "pet" that can tell whether it's hungry/happy by color
- Multi-stage projects — the kid builds and programs in 2-3 steps
Typical SPIKE Essential project: 60-90 minutes building + 30-45 of programming. Often continues into the next lesson.
Visual programming — a difference that's not obvious
WeDo 2.0 has its own programming interface that is simpler. Fewer options, bigger blocks, fewer mistakes. Good for a 7-year-old.
SPIKE Essential uses "Word Blocks" — Lego's enhanced version of Scratch with the same block-stacking model. This language is closer to "real" Scratch and is considered a stepping stone to text-based programming (Python).
Practically: a kid who gets into SPIKE Essential at 9 will move into Python at 11 relatively easily. The leap from WeDo 2.0 to Python is bigger.
What we use at DigiKids
For our age groups:
- Yellow Belt (5.5–7.5 years): Lego Essential set (basic, no motors) + Scratch Junior
- Green Belt (6.5–7.5 years): WeDo 2.0 + Scratch Junior
- Blue Belt (7–10 years): WeDo 2.0 + Scratch + Micro:bit
- Red Belt (9.5–12 years): SPIKE Essential + Scratch
- Brown Belt (10–12 years): SPIKE Essential + MakeCode
- Black Belt (11–13 years): SPIKE Prime or Mindstorms (their pick)
You see the pattern: WeDo 2.0 is for the intro, SPIKE Essential is for a more advanced level, SPIKE Prime / Mindstorms is for the oldest group.
Buy for home or not?
Buy if:
- The kid has been in class for 6+ months and is asking to keep working at home
- You have time (10-15 hours) to dive into the material together
- There's another kid in the home who'll take over when the older one moves up
- You're considering switching the kid to self-study outside class (we don't recommend it, but it's a real reason)
Don't buy if:
- The kid hasn't tried the set before (90% odds it ends up in the closet)
- You don't plan to help in the first few weeks
- The kid is just thinking about signing up for a class — wait a couple of months
- You don't have a clearly defined goal ("maybe they'll fall in love with it" is a weaker strategy)
The most common scenario we see: a parent buys SPIKE Essential for 32,000 RSD with no context. The kid is into it for 2 weeks, then stops. The parent asks us "can we use it in class?". We can, but then the set comes back home — and stops again. If you were considering 30,000 RSD for an expensive set, consider 30,000 RSD for one DigiKids semester cycle — probably a better investment.
Another option — smaller sets
If you want a Lego robot toy that's realistic for a home setting:
- Lego Boost (Vernie) — ~14,000 RSD, more fun than either educational set, less "serious", ideal for ages 7-10 when the kid isn't in a class
- Lego Mindstorms (buy a used EV3) — if the kid is 11+ and comes with experience, a second-hand EV3 for 8-15,000 RSD is solid
DigiKids Vračar uses all three sets at different belt levels. Before you buy for home — give us a call, we'll advise honestly. A free trial is probably the smarter first investment.
