Trackbot for computer vision exercises
thingiverse
3D printed robot designed for computer vision and artificial intelligence exercises. First attempt at tracking an object with a camera using OpenCV: https://vimeo.com/198101036. Print Settings: - Printer Brand: MakerBot - Printer Model: MakerBot Replicator Mini - Rafts: Yes - Supports: No - Resolution: 0.15mm - Infill: 50% Notes: The MakerBot mini is too small for the entire robot, so it was cut in half. How I Designed This: I used Thingiverse's http://www.thingiverse.com/thing:597267 design but replaced continuous rotation servos with generic DC motors and added bearings to smooth wheel rotation. For power supply, two independent USB power banks (2.1A and 2.4A) were used instead of AA batteries - one for the Raspberry pi and one for the servos and motors. Choosing a safe and strong enough power source was a challenging part of this project. To power motors and servos, a step-up converter was used to boost 5.0V to approximately 7.5V. I control DC motors and servos using PCA9685 PWM.
