Last updated 1 year ago

Odometry is a method used to estimate the position and orientation of a robot by tracking its wheel movements accurately. Odometry pods are specialized sensor assemblies that usually contain encoders and other sensors attached to the robot's wheels.

These pods help the robot track the distance traveled by each wheel and the robot's turning angles. By analyzing the data from the odometry pods, the robot's software can calculate and maintain a relatively precise estimate of its position and heading on the field. This information is valuable for autonomous navigation tasks and performing specific actions during the competition.

What makes a good odometry pod design?

  • Size and Weight Limitations: FTC robots have size and weight limitations, so the odometry pod should be designed to be compact and lightweight to fit within these constraints.

  • Compatibility with Robot Drive System: The odometry pod should be compatible with the robot's drive system (e.g., mecanum wheels, holonomic drive, tank drive). The design should account for the specific kinematics of the robot to calculate accurate position and orientation.

  • Easy Installation: The odometry pod should be easy to install and calibrate on the robot. Consider using mounting brackets or 3D-printed parts for easy attachment.

  • Robustness: FTC robots often encounter rough field conditions and collisions during matches. Design the odometry pod to withstand these conditions and maintain accuracy even after impacts.

  • Field Calibration: Design the odometry pod to allow for quick and reliable calibration before each match. Field calibration is essential to account for small variations in the playing field.

Ultimately, a successful odometry pod design for FTC should strike a balance between accuracy, affordability, ease of integration, and robustness to help the team achieve better performance in the autonomous navigation challenges.
