Robotics is a vast, thrilling, and sometimes overwhelming interdisciplinary field involving physics, engineering, and computer science. This kit gives kids a simple, fun, and customizable introduction to robotics that lets them build eight motorized machines controlled by programs and an ultrasound sensor. Kids code the programs using an easy, visual programming app on a tablet or smartphone, which connects to the robot models via a wireless Bluetooth connection.
The ultrasonic sensor works on the same principle as sonar. It sends out sound waves, which bounce off objects. The sensor interprets the echoes returning to it, and from this detects objects in the path of the sensor. Using the app interface, you can program the robots you build to behave based on the feedback coming from the ultrasound sensor.
Build a bipedal robot that walks forward on two legs and pivots to avoid obstacles in its path. An awesome beetle robot moves backwards or forwards in response to an obstacle, and opens and closes its pincers. Construct a funny crocodile model that wags its tail if no object is in sight, but then opens its giant jaws when an object approaches. Using an additional smartphone and tablet, you can even hack together a cute little spy bot that roams around and streams video back to the tablet screen. A cool tiltrotor aircraft model simulates vertical takeoff and landing by rotating its propeller blades 90 degrees. You can also assemble other fun robots including a robo dog and robotosaurus. After you have learned how the technology works, you can build and program your own robots using the kit’s 230 building pieces.
A full-color, 64-page step-by-step illustrated manual helps kids assemble all of the models and teaches them about robotics in the real world. The visual programming language allows you to command the robots’ motors to move at different times, different power levels, in different directions, and in response to the data from the sensor. You can also add simple sounds to your programs. Requires a tablet or smartphone running iOS or Android. Please check the app stores for compatibility and device requirements.

Robotic Components:
Ultrasonic Sensor
Your robot’s eyes! The ultrasonic sensor helps your robots gauge distances and determine where objects are. Using the core controller, the ultrasonic sensor is able to detect an object and measure its proximity. Technically it works like a sonar system: a sound is sent out and received again when it bounces off obstacles.
Light Sensor
Detect light intensity! The light sensor assists in helping your robot to “see.” It enables your robot to distinguish between light and dark, as well as determine the light intensity in a room or the light intensity of different colors.
Touch Sensor
Your robot’s fingers! The touch sensor measures information arising from physical contact with objects, enabling your robotic creation to “feel” things in front of it! The sensor can detect single or multiple button presses, and reports back to the core controller, which decides what to do according to the program. The kit includes two touch sensors.
Precision Motor
Take precise steps! The two precision motors allow your robot to take accurate and powerful steps with complete motor control! The kit includes two servo motors.
Geared Motor
Drive your robots! The two geared motors bring motion to your robots: Connect the motors to gears, wheels, and other pieces to move your robots in many ways. The kit includes two regular motors.
CB1 Core Controller
Your robot’s brain, ears, and voice! The CB1 core controller wirelessly connects the app on your tablet to the motors, sensors, microphone, speaker, and LEDs.
Speaker
Your robot’s voice! The loudspeaker integrated into the core controller allows you to program your robots to make sounds.
Sound Sensor
Your robot’s ears! There is a microphone on the core controller that can detect sounds. You can program your robot to react accordingly. So if you clap your hands once, it can mean one thing, and it you clap twice, it can mean a different thing. The sound sensor is able to measure noise levels around 3–6 kHz, where the human ear is most sensitive.
You will also need: 6 AA batteries (1.5-volt, type AA/LR6) or 6 AA rechargeable batteries (1.2-volt, type AA, HR6/KR6); Tablet and/or PC with Internet access. To use an external DC power source, a 5V 2.5A DC power supply is recommended.
Requires a tablet running iOS or Android. Check the app stores for compatibility and device requirements.

Chemistry is the science of materials, their properties, and how they react with each other. All materials are made of atoms. Why do some atoms combine with each other while other atoms do not? Because atoms just want to be happy!
Of course, atoms don’t really have feelings. But they do have observable behaviors. And atoms tend to be more stable, or “happy,” when they have certain numbers of electrons whizzing around their cores. Where do they find extra electrons if they need more to be happy? From other atoms that have too many electrons, of course! When atoms share or exchange electrons to be happy, they stick together. Happy atoms form molecules!
With this revolutionary approach to teaching chemistry, you can make your own happy atoms! This physical and digital system lets you discover the world of molecules in an intuitive, hands-on way. Using a set of 17 atom models representing 6 different elements, you can assemble your own molecular models. The atoms connect easily with magnets: metal tips on the ends of rubbery arms, which represent free electrons, snap onto magnetic bonding sites on the atom spheres, which represent empty spots for electrons in the atom’s outermost electron shell.
With the Happy Atoms Introductory Set, you can snap together hundreds of different molecules. Because the atoms already have the correct number of free electrons and empty bonding sites, it is difficult to build a molecule that doesn't actually exist. Happy Atoms function like the building blocks of the universe!
The digital component takes this molecular modeling system to the next level. Using the Happy Atoms app and the camera on your tablet or smartphone running iOS or Android, you can scan molecules you build. The app then uses state-of-the-art image recognition technology to identify the molecules. After a molecule is discovered, the app presents information about it, including its composition, usage, properties, hazards, formula, and structure. The app can recognize hundreds of the molecules that you can build with this set. It presents detailed information about 49 of the molecules you can build.
The app is a fun and interactive chemistry curriculum. It takes you on guided quests to discover new molecules and learn about them. You can track your progress with the app, collecting sets of molecules that you have built and explored.
Many people think of chemistry as complicated and hard to grasp. New technology now enables us to take this innovative approach to teaching chemistry, making it more tangible and instinctive than ever before. Requires a tablet or smartphone running iOS 8 (or later) or Android 4.4 (or later, with 1 GB RAM, dual-core processor, and camera).

This astonishing wall-climbing robot has a motorized air suction system that enables it to walk vertically up and down perfectly smooth surfaces, like glass, plastic, whiteboards, and glossy laminates. The battery-powered motor drives an innovative gear system that produces a rotating motion making the legs move back and forth and up and down, mimicking a real gecko — so two of the feet are touching the wall while the other two feet are lifted off of the wall, in an alternating motion. At the same time, the gear system drives an air pump that creates a vacuum at the two feet touching the wall while blowing air outward at the other two feet. In this way, two of the feet are always holding the model to the wall, while the other two feet are pushing off and stepping forward. You can build six other models and conduct experiments with suction to learn about air pressure and the mechanical physics of this unique device. Build models of an industrial robotic arm with a vacuum suction cup gripper, crawling inch worm, smartphone holder, suction tow truck and car, ellipsograph, and suction gun.
