How to pick the right one
Common questions
What is the best robot building kit for a 7 year old?
The LEGO Boost Creative Toolbox is suitable for ages 7 and up. It uses LEGO bricks that are familiar and easy to handle. The app offers guided instructions and coding challenges that are appropriate for young learners.
Do robot kits require a smartphone or tablet?
Not all. Some kits, like the Makeblock mBot, can be controlled via remote or programmed on a computer. Others, like LEGO Boost and Sphero BOLT, require a compatible tablet or smartphone for the app. Check the requirements before buying.
Can these kits be used for classroom STEM education?
Yes, many robot kits are used in classrooms. Kits like Sphero BOLT and Makeblock offer educational resources for teachers. They align with curriculum standards and can be used for group activities.
How long does it take to build a typical robot kit?
It varies. Simple kits like the 4M Doodling Robot take about 15 minutes. More complex kits like the Thames & Kosmos Robotics Workshop can take several hours. It also depends on the child’s age and experience.
Are replacement parts available for robot kits?
For major brands like LEGO, Makeblock, and Sphero, you can often find spare parts on their websites or through Amazon. For less common brands, it may be harder to find replacements.
What age is appropriate for advanced robot kits?
Advanced kits that involve soldering or text-based programming are typically suitable for ages 12 and up. The Thames & Kosmos Robotics Workshop is recommended for 10 and up, but some kits are designed for teens.
Do these kits need batteries?
Yes, most robot kits require batteries. Some use AA batteries, others use rechargeable batteries or include battery packs. The product description will specify the type and number needed.
