B. Building vs. Coding: Structural Freedom and Durability
Building vs. Coding: Deciding Your Focus
LEGO Mindstorms wins for open-ended building, giving you 949 pieces for unique designs. This is the opposite of the Sphero BOLT's ready-to-use ball shape with built-in sensors. The mBot's aluminum body is strong and can be expanded. Both Botley and Codey Rocky focus on quick coding first, rather than on construction. For aspiring engineers, LEGO's versatility wins, but for pure coding focus, Sphero's integrated system reduces setup time.
Durability tests showed all holding up well, with Sphero's waterproof shell edging out for outdoor use.
C. Cost and Long-Term Value
Maximizing Your Investment: Cost, Learning Plans, and Extra Gear
Starting prices go from $70 (mBot) up to $360 (LEGO), but the true value also includes extras. The LEGO system works with all their bricks, though extra parts are expensive. Sphero gives free updates right through their app. The mBot is cheap to start and offers add-on kits for the best value. Botley is good for small budgets with no-cost activities. Learning support is different for each—Sphero and Makeblock are great with free lesson plans, which makes their educational value last much longer.
