Gravity: TT Motor Encoders Kit

Wheel Encoder Kit for TT Motors provides accurate rotational feedback for small robotics platforms using TT-style micro gear motors. Designed for integration with Micro DC Geared Motor assemblies, the encoder accessory converts wheel rotation into measurable angular displacement signals, enabling precise speed measurement and motion control. A non‑contact optical detection method improves durability while avoiding mechanical wear. The kit includes encoder sensors, grating disks, plastic mounting components, and fastening hardware, forming a compact sensing solution for rover platforms, line‑following robots, and mobile robotics prototypes requiring real‑time wheel rotation monitoring.

Non‑Contact Optical Rotation Detection

An optical grating disk and sensor pair converts wheel movement into digital pulses without physical contact between sensing elements. Such non‑contact signal acquisition reduces mechanical friction and improves long‑term stability compared with contact‑based sensing approaches. With a resolution of 20 pulses per revolution (PPR), the rotation sensing module provides sufficient precision for speed calculation, closed‑loop motor control, and odometry tracking in compact robotics systems using TT gear motors.

Gravity Plug‑and‑Play Interface

A Gravity interface simplifies electrical connection through standardized three‑pin cables, reducing wiring complexity during robotics assembly. The motion sensing module connects directly to an Arduino IO Expansion Shield or Raspberry IO Expansion Shield, enabling rapid deployment with common development controllers. Gravity ecosystem compatibility also streamlines integration into educational robotics kits, prototype vehicles, and embedded motion‑tracking systems built around Arduino or Raspberry Pi platforms.

Reliable wheel‑rotation feedback enables improved navigation, speed regulation, and motion analysis in mobile robots. This TT motor encoder accessory supports differential drive vehicles, rover platforms, robotics experiments, and STEM learning projects where wheel displacement measurement enables odometry estimation and closed‑loop motor control.
