Products & Kits
What age are your kits designed for?
Each kit carries its maker’s own age grade. The Smart Farm, Smart Home and Biped Robot are graded ages 8 and up; the Weather Station and the Bionic Spider are graded ages 10 and up. Younger builders usually want an adult nearby; from about 10 most children work through a kit on their own.
Do I need any additional tools or parts?
Every kit includes the board, the sensors, the wiring and the structural parts, and no soldering is required — every connection is a breadboard, a jumper wire or a plug-in connector. You supply a computer to upload the code (Windows, Mac or Linux), and AA batteries for the two robot kits.
Do I need coding experience?
Not at all. Every kit includes starter code that works as supplied, and the manufacturer’s booklet walks through each step. Changing a value and seeing the hardware react is usually where the learning starts.
Are batteries included?
It depends on the kit. The Smart Farm, Smart Home and Weather Station run from USB power. The Biped Coding Robot and the Bionic Spider need 4 x AA batteries, which are not included — the battery holder is in the box, the batteries are not.
Can I buy replacement parts?
If a part is missing from the box or arrives broken, email us with your order number and we will send it free of charge. If your child loses or breaks a part later, email us anyway — we will source it from the manufacturer and tell you what it costs before anything is sent.
Returns & Refunds
What is your return policy?
We offer a 30-day return policy on all unopened kits. If a kit is defective, we will replace it or issue a full refund.
How do I start a return?
Email trinkolostore@gmail.com with your order number. We will email you a prepaid return label within one business day.
Technical Support
My robot is not working. What should I do?
First, check the troubleshooting section in your kit manual. If you are still stuck, email us with a photo or video of the issue. We answer email within one business day.
Are instructions included, and is there anything to watch?
Every kit ships with the manufacturer’s printed, illustrated booklet, and the starter code is listed on the product page. We do not publish video tutorials yet.
Can I customize the code?
Absolutely! All our kits use open-source Arduino code. You can modify the code, add new features, and make the project truly your own.
