Software That's Easy to Use

If hardware is the heart of your EZ-Robot, then software is the soul. ARC is an easy-to-use, versatile, and powerful robotics software platform that scales with users as their programming skills grow.

• Start with “Drag and Drop” coding languages like RoboScratch and Blockly.
• Transition to text-based coding languages like Python, JavaScript, and EZ-Script (a C# derivative).
• Add advanced robotics functionality such as camera tracking, speech recognition, Wii controllers, sensors, and Artificial Intelligence (e.g., Microsoft’s Cognitive Services).

Teach Your Robot Animations

The Auto Positioner in ARC is used to animate EZ-Robot movements. Simply move your robot into positions to create an animation routine. Play back actions based on triggers, such as when the robot sees your face or responds to a voice command.

Teach your robot how to move, dance, climb stairs, and more!

EZ-Robots Are Visual Learners

A robot wouldn't be a robot without a camera to interact with its environment. Each EZ-Robot comes with a camera installed in the head for advanced vision learning, detection, and tracking.

Your EZ-Robot can be programmed to recognize:

• Colors
• Objects
• Faces
• Motion
• Glyphs
• And more!

Get a Grip

EZ-Robot's compact grippers are powered by strong metal geared servo motors, allowing your robot to interact with soft, light objects.

---

Simply Clip and Play

Customize your robot with EZ-Bits. All EZ-Robots include EZ-Clip connections, making innovation and customization as fast as it is fun.

• Slide the tab into the slot to establish a secure bond.
• Separate parts by sliding them apart.
• Connect multiple EZ-Bits to create arms, legs, or anything else you dream up!
