How Robots See
Discover how intelligent machines transform flat camera feeds into real-world action. Learn how robots detect objects, measure depth, track targets, and map unfamiliar rooms using video.
Like Duolingo, but for How Robots See. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Making Sense of the Camera Feed and Guiding Physical Action with Video. It starts from scratch.

Key ideas in How Robots See
- A camera feeds the robot a grid of numbers representing pixel brightness and color rather than named objects
- Abrupt mathematical jumps between neighboring pixel values reveal the physical edges of items in the frame
- Robots locate target borders by tracing these sharp contrast boundaries across the numerical grid
- Standard RGB color values change drastically when shadows darken an object, confusing the robot
- HSV separates the actual tint or hue from how bright or shaded the pixel is
- Separating brightness allows a robot to track the same colored item under shifting lights and shadows
- Thresholding converts every pixel to either pure white (target) or black (background)
- Discarding subtle shading and interior textures leaves a clear silhouette that onboard processors can parse rapidly
- Processing simple binary pixels keeps reaction times fast enough for real-time motor control
- Motor controllers cannot efficiently calculate drive angles from thousands of separate raw pixel points
- A bounding box wraps the matching pixel cluster into a simple rectangle defined by its boundaries
- The box's center coordinate tells the robot which way to steer, while its height or width indicates relative distance
- Background objects often share the exact same color as the target object
- Aspect ratio compares an object's detected height to its width
- Filtering bounding boxes by their expected aspect ratio stops the robot from chasing color-matched background shapes
- A single standard camera collapses real 3D space onto a flat 2D grid of pixels
