EZ-B v4/2 Developer Kit

Ease and power are reasons that ezrobot has been the driving force behind countless robots for hobbyists, competitions, schools and R&D facilities in over 120 countries. We are committed to maintaining ongoing development by implementing new features to increase your robot’s functionality.

This powerful kit is perfect for any skill level – from beginner to advanced – with its graphical control interface, custom scripting abilities, and full-featured SDK.

The ez-bv4 is the brain and nervous system of your ezrobot. With the electronics protected by a stylish plastic shell, the ez-bv4 clips into your ezrobot Revolution chassis or custom robot.

At the heart of over 20,000 robots worldwide is the ez-bv4/2. The world’s most powerful and compact robot brain, suitable for all skill levels – from beginner to advanced. The stylish white plastic shell protects the speaker and electronics, with a speaker chamber for clear, enhanced audio. For advanced users, the ez-bv4/2 may be removed from its casing and mounted directly in your custom robot. [Learn More]

You care about energy consumption with electronics. That’s why ezrobot designed an innovative low energy digital switching power supply for our products. While most electronics dissipate heat to lower voltage, our products use an energy efficient power supply which generates practically no heat! Welcome to the future! 🙂

EZ-Robot Revolution introduces the world’s easiest, most powerful and creative robots for R&D, experimentation and STEM education. Revolution is modular, so there is no limit to your creativity. These robots are assembled with ez-bits using clip’n’play technology for endless configurations!

The Brain

At the heart of your Revolution Robot is our exceptionally compact, intelligent and powerful EZ-B family of robot brains. The EZ-B provides features to your robot thought only possible in science fiction with walking, talking, and learning capabilities. The EZ-B v4 brain gives robot creations the ability to learn, interact and play. Meanwhile, the EZ-Robot camera equips robots with the ability to recognize faces and track objects. Using a PC or mobile device, control EZ-Robots over a Wi-Fi connection. The EZ-B brain leverages the power of Cortex ARM processors. The EZ-Robot brain is expandable to grow with your robot by supporting dozens of additional sensors, displays and servo-motors.

Unified

EZ-Robot is first in the industry to successfully provide a complete unified robot platform which combines powerful hardware, clip’n’play modularity and innovative software that pushes the limits of robot technology. The EZ-Builder software controls, programs and shares EZ-Robot Revolution behaviors, configurations and personalities. Customize Revolution Robot with EZ-Builder’s easy-to-use 3D graphical designer and share the configuration on the EZ-Cloud App Store within the globally community. Programming an EZ-Robot is graphical, easy and scales between beginner and advanced users. You can even make your own mobile apps with a simple drag-and-drop interface which run on your iOS or Android device, instantly. There is absolutely nothing else like it!

Education

A future of robotics needs education, today. Revolution isn’t limited to fun and games, EZ-Robot empowers educators to teach real-world robot applications which give students a leading-edge advantage in the up and coming robot industry.

Remote Processing

EZ-Robot products offload processing to more powerful third party CPUs, such as an iOS/Android mobile device, tablet, or PC. This approach provides users with an easy-to-use and feature rich development environment which, unlike competitive products, is not limited to programmers. This approach not only saves weight and space on the robot chassis, but also power consumption. This is an efficient approach to direct battery consumption where it is needed on a robot most… to its motors.

Scales With New Technology

Another benefit with offloading processing is that product features mature in parallel with dependent device technology growth (PCs, Mobile Devices). This offers EZ-Robot parallel development initiatives in conjunction with supporting industries, which leverage EZ-Robot’s processing capabilities that result in additional features and increased usability. In short, new EZ-Robot features are added as computers, mobile devices and software evolves.

Point & Click Programming

Using PCs and Mobile Devices for the Robot GUI offers high level (easy) and low level (difficult) programming features, neither of which sacrifice functionality. This enables creative designers, dabblers and programmers to produce robots which would otherwise require teams of programmers and engineers years of work.

Creative Approach

Competitive products which offer embedded device programming ability (i.e. microcontrollers) require advanced programming experience, which contradicts educational and mass-adoption initiatives – not everyone is a programmer or has an interest in programming. While embedded device programming has historically been a familiar method in robotics, today’s highly computational and feature-rich products require distributed processing. This methodology splits the robot industry into several fields and categories. Similar to other developed industries (automotive, computers, medical), robotics is splitting into many fields of discipline. Each discipline’s responsibility is becoming too advanced for an individual to be great at all of them. EZ-Robot’s user workflow was architected for this approach. While competitive robot products focus on either programming (microcontrollers) or usability (toys), EZ-Robot differs by providing components for all disciplines within the industry of robotics.

Where Do I Start?

Interested in a career in a field of robotics? As you can see, robotics is dividing across many fields, each with their own discipline. What responsibility from the list above interests you? There are many disciplines, which is why the term “roboticist” is a career title of the past. When focused on a single task, we do it really great. Each discipline of robotics also requires immense focus, which is why learning with EZ-Robot is your best option. We provide hundreds of complete software controls and unified hardware to “fill in the blank” of disciplines that you do not find interesting or are too challenging. Perhaps you enjoy designing movements, but not programming. Or, maybe you enjoy vision capabilities, but not electronics. With EZ-Robot, focus on customizing the behaviors that you are interested in, and leave the rest to us!
