## Overview

The Thames & Kosmos Robotics Smart Machines Junior STEM Kit is a beginner-friendly robotics set designed for kids 8 and up. It features a 9-inch buildable robot controlled via built-in buttons or a free block-based coding app, enabling over 200 programmable actions. This kit promotes essential STEM skills like coding, problem-solving, and critical thinking through hands-on assembly and interactive play, backed by Thames & Kosmos’ award-winning educational expertise.

## Description

Build and program your own robotic pal with this simple, fun, and customizable introduction to robotics. Assemble the durable, plastic building pieces into a 9-inch tall bot, then pair it with the free app on your smart device to unlock all of Junior’s capabilities. You control Junior’s movements and sounds! Program its movements directly on a built-in keypad or use the easy, visual interface on the app. Drive it around by remote control or use your device as a gyroscope. Play a make-believe robot workshop game in the app to diagnose any onboard issues. Junior’s microcontroller (or “brain”) has separate inputs for the LED lights that light up its eyes, a speaker, two motors (left and right), and a battery. A full-color, 32-page step-by-step illustrated manual explains how Junior’s functions relate to each of these elements, walks kids through the construction process, and helps them make the most of the app’s features – all while teaching them about robotics in the real world. The app requires a tablet (recommended) or smartphone running iOS or Android. Please check the app stores for compatibility and device requirements.
