Anatomy of Bingo

Bingo, a robotic creature designed to perceive its surroundings, move through the world, remember what it encounters, and express a personality. Design by Body Shop, engineering by Gentle Systems.

Here's a short breakdown of the engineering and thinking behind four of the systems that give Bingo a mind of its own: mobility, sensing, expression, and memory. And what it took to fit them all inside one small body.

After all, a wild computer deserves an equally wild amount of imagination.

Bingo is engineered to make ordinary movement feel natural.

Twelve custom actuators give each leg three axes of movement, while drone motors, compact gearboxes, lightweight polymers, and hollow 3D-printed parts keep power high and weight low. Every gram saved means more room for batteries, more time roaming, and enough strength left to jump.

That range turns locomotion into expression. The same hardware that gets Bingo across a room lets it communicate attention, excitement, hesitation, and curiosity through the way it moves.

Can unpredictability give a machine character?

Predictability makes machines easier to engineer, but it can also make them feel mechanical. For Bingo, a degree of unpredictability creates room for personality to emerge: unexpected movements, changing interests, and moments that feel discovered rather than programmed.

Bingo is also designed to be small — a kind, gentle companion, and its size reflects that. But a companion needs more than gentleness to feel like one: it needs character. And character needs room to be a little autonomous — to explore, move between floors, and keep a sense of what's happening around it.

Before Bingo can remember, wander, or develop opinions, it first has to pay attention.

Inside a head roughly the size of a small pomelo, sensors compete for millimeters. LiDAR maps the space around it; RGB, depth, and infrared cameras extend its vision; and a spatial microphone array lets sounds become points of interest before they enter view.

More unusually, Bingo can smell. A carbon nanotube sensor detects subtle changes in the air, picking up traces that precede things and linger after they're gone. Capacitive, motor, and ground-force sensors complete the picture through touch, resistance, balance, and impact.

Together, these systems give Bingo the layered sense of the world, memory will need to work with. Fitting them all meant every component had to earn its place.

Taste remains an unsolved problem.

Remembering everything is not natural. Perhaps a little creepy, even.

Bingo moves through the world gathering a rich register of reality in color, depth, sound, and smell. But storing everything would create both a privacy problem and a storage one. So rather than treating memory like a recording device, we designed it to behave more like our own.

Perception begins at the highest fidelity available — but only for as long as it's useful. Once a memory has served its function, its fidelity begins to fade: partly to shape character, keeping what matters and letting the rest blur, and partly as a safeguard, protecting privacy and staying within the bounds of data law. A Gaussian splat becomes a point cloud. A point cloud becomes a low-poly scene. A low-poly scene becomes a string of emojis. Eventually, even those disappear.

What remains might be a vague recollection. A preference. An affinity for something Bingo can no longer fully trace back.

The result is a memory architecture designed around what to keep and what to let go.
