Sphero littleBits RVR+ Topper Kit - Combine Programming and Mobile

In this review the Sphero littleBits RVR+ Topper Kit is examined as a classroom and maker-space accessory that bridges block and text coding with hands-on engineering. The kit is best for educators and student groups who already own an RVR and want to add modular electronics that can be powered and mobilized by the RVR platform. Its single biggest selling point is the ability to program both littleBits modules and the RVR from the same editors, giving teams a straightforward path from concept to a roaming invention.

Key Features

• One kit per RVR: Designed as an add-on, the kit lets a single RVR support a group project with dedicated littleBits components for easy classroom deployment.
• RVR onboard power: The RVRs built-in power source can drive your littleBits circuits so inventions become mobile without separate batteries or complex wiring.
• All terrain treads: RVRs treads make the combined littleBits inventions portable across classroom floors and low obstacles for realistic testing.
• IR sensor interaction: Program the RVRs IR sensors to respond to the littleBits IR remote trigger to create mazes, gates and interactive challenges.
• Unified programming: Use the littleBits micro:bit adapter to program both littleBits and RVR in Microsoft MakeCode or the micro:bit Python editor for a single development workflow.
• Collaborative design: The kit encourages team roles so one group can focus on programming while another tackles engineering and assembly.

Who It's For

The RVR+ Topper Kit is aimed at educators, makerspaces, and STEM clubs that already own an RVR and want an expandable way to teach coding alongside physical design. It suits middle and high school classrooms where groups benefit from split roles and hands-on iterative testing.

Those who should look elsewhere include buyers who do not have an RVR yet or need a standalone littleBits starter set; this product is explicitly an add-on and requires an RVR to realize its mobility and power benefits.

Pros & Cons

Pros

• Enables combined programming and engineering projects by linking littleBits to the RVR platform.
• Uses the RVRs power and treads so inventions are immediately mobile without extra power packs.
• Supports Microsoft MakeCode and micro:bit Python editor so teams can use block or text coding.

Cons

• Requires one RVR per kit, so classroom budgeting must account for the base robot separately.

Our Verdict

The Sphero littleBits RVR+ Topper Kit is a practical add-on for classrooms and makers that already own an RVR and want to blend block and Python coding with physical engineering. It delivers real value by letting teams power and mobilize littleBits creations while keeping development in one set of editors, making it a smart purchase for educators focused on collaborative STEM learning.

Frequently Asked Questions

Do I need an RVR to use this kit?
Yes. The kit is intended as an add-on and relies on an RVR for power and mobility.

Which editors can I use to program both devices?
Both Microsoft MakeCode and the micro:bit Python editor are supported to program littleBits and the RVR together.

Can I create interactive challenges with the kit?
Yes. The RVRs IR sensors and the littleBits IR remote trigger let you build mazes, gates and interactive inventions.
