3pi Robots And Accessories

Palm-sized differential‑drive mobile platforms with integrated sensors, displays and compact motor drives. They are supplied as ready-to-run robots or as build kits, offering different motor gearings for higher speed or greater torque and a choice of control‑board options from classic 8‑bit controllers to modern 32‑bit microcontrollers.

Common uses include line following, maze navigation, control and sensing experiments, classroom exercises and compact robot competitions. Key strengths are small form factor, on‑board reflectance sensors and displays, reliable drive hardware, and accessible expansion headers for custom sensors or communications. Compared with bare chassis or larger rovers, these platforms provide more built‑in electronics and faster integration for embedded robotics projects.
