Integrates a full 9-axis inertial measurement unit
The Pololu 3pi+ 32U4 OLED Robot - Hyper Edition (15:1 HPCB Motors), Assembled is a sophisticated mobile platform designed for advanced users, featuring an Arduino-compatible ATmega32U4 microcontroller. This compact robot, measuring just 9.7 cm in diameter, integrates a range of advanced components including dual quadrature encoders for precise motor control, a full inertial measurement unit, and a graphical OLED display. The Hyper Edition is equipped with high-speed 15:1 HPCB 6V Micro Metal Gearmotors, making it exceptionally fast and challenging to control.
The robot's microcontroller is preloaded with an Arduino-compatible bootloader, facilitating programming through a USB connection. Users can access the robot's power rails and I/O lines via expansion ports, allowing for customization and enhancement with additional peripherals. The 3pi+ 32U4 OLED is equipped with two H-bridge motor drivers and a variety of sensors, including five reflectance sensors for line-following and edge-detection, and front bump sensors for collision detection.
A unique power system ensures the motors operate at a constant 8 V, independent of battery charge levels, maintaining consistent speed. The robot also features three on-board pushbuttons for user interaction, a buzzer, and indicator LEDs for feedback. The bottom-loading battery holders provide easy access to batteries, even when additional levels are added to the robot.
Note: This edition is recommended for advanced users due to its high speed and difficulty in control, with a strong recommendation to keep motor speeds below 50% to prevent damage from impacts.

The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
