Project Overview

A ROS2 Package hosting a Kalman Filter from scratch to combine data from a 9-DoF IMU and a time-of-flight distance sensor attached to the end-effector of a delta robot. The filter will be used to estimate the position and velocity of the end-effector in 3D space.Results will be visualized with a 3D plot, written in C++ and compared to kinematics estimations from the robot's control system.

Learning Concepts: - Kalman Filtering - Reading I2C data from high-speed sensors - Eigen Library (C++ Library for Linear Algebra and Matrices) - Graphics and Plotting in C++

Sensor Details

BNO085 IMU

IMU

The BNO085 IMU has the following features:

  • Acceleration Vector / Accelerometer
    • Three axes of acceleration (gravity + linear motion) in m/s^2
  • Angular Velocity Vector / Gyro
    • Three axes of 'rotation speed' in rad/s
  • Magnetic Field Strength Vector / Magnetometer
    • Three axes of magnetic field sensing in micro Tesla (uT)
  • Linear Acceleration Vector
    • Three axes of linear acceleration data (acceleration minus gravity) in m/s^2
  • Gravity Vector
    • Three axes of gravitational acceleration (minus any movement) in m/s^2
  • Absolute Orientation/ Rotation Vector
    • Four point quaternion output for accurate data manipulation

Thanks to the sensor fusion and signal processing wizards from CEVA, with the BNO085 you also get:

  • Application Optimized Rotation Vectors
    • For AR/VR, low latency, and low power consumption
  • Additional Base Sensor Reports
    • Separate and simultaneous outputs of Calibrated, Uncalibrated + Correction, and Raw ADC outputs for the Accelerometer, Gyro, and Magnetometer
  • Detection and Classification reports:
    • Stability Detection and Classification
    • Significant Motion Detector
    • Tap, Step, and Shake Detectors
    • Activity Classification

VL53L1X Time of Flight Distance Sensor

Time of Flight Sensor

The VL53L1X ToF Sensor is capable of precise distance measurement within a range of $[30, 4000]$ mm, with up to a 50Hz update rate and a $27^\circ$ field of view which can be configured with a programmable Region of Interest (ROI).
