## 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.

Review: Cool Robot - This is a really well made robot and not hard for a 9yr old to build alone. The instructions to build are easy to follow. The first words of my daughter after turning it on and seeing it work were “wow this is cool, really cool”, I agree with her and it seems that the app has some good features as well. The kit contents are very well organized with lots of extra screws.
Review: Highly recommend! - This was a great gift for our 10 year old! He enjoyed building it along with playing in the app to code and create for his robotic machine. Hours and hours of fun! Highly recommend!

### ⭐⭐⭐⭐⭐ Great first programmable robot
*by J***N on May 24, 2025*

An easy first robot/programming experience. Built it with a group of children ages 7 to 14. Instructions clear, app clear and worked right away. Took about 3 hours total over 2 days from opening the box to having it move. Very worth the price.
