  3. Why Beagle Bone Black? Features ⋄ Communication via Ethernet ⋄ ROS and Software running on Ubuntu ⋄ Pluggable Components Connectors: ⋄ 33x digital I/Os, 4x PWM, 4xADC ⋄ SPI, CAN, and I2C Bus ⋄ Ethernet, USB, HDMI ⋄ SD-Card Slot 3

  4. External Components ⋄ Inertial measurement unit (Adafruit LSM9DS0) ⋄ Light barrier with IS471 and IR-LED ⋄ High power motordriver ⋄ Optical Flow Sensor ⋄ Servomotor 4

  5. In Progress: New charging mechanism for the capacitor Idea: Charging the Capacitor with a transformer Possible advantages: ⋄ Capacitor is charged more quickly ⋄ Galvanic isolation / more safety ⋄ More energy-efficient Disadvantages: ⋄ More weight ⋄ Lack of experience 5

  6. Localization Idea: Using gradient descent in the particle filter Possible advantages: ⋄ Global localization ⋄ Low computational power needed ⋄ Precision Open questions: ⋄ How selecting number of gradient steps and particles? ⋄ Is it really better? 6

  7. Simple Depth Based Obstacle Detection Approach: ⋄ Detect the ground plane ⋄ Compress camera data by computing a voxel grid ⋄ Remove all voxels close to the ground plane ⋄ Clustering the remaining voxel through a distance metric 7
