Concept · a body for the mind

The mind, given a body.

Transphere is the OpenJelly mind sphere made physical. Every disc on the shell is one concern: a sensor, an actuator and a joinpoint on the bus. The shell is printed for each version of the mind.

Scroll to take it apart, step by step. Hover a part for its name. A concept render, not a product.

1 · Concern discs

One disc, one concern.

150 discs lift off the shell. Each is one concern of the mind: every one senses light and can push six millimetres along its own normal; four carry a camera, twelve a microphone, eight a speaker. Their sizes follow the concerns' weights, as the circles do on the mind page.

2 · The frame

A truss printed for each version of the mind.

Under the discs is an open truss with one seat per concern; the seats are the plunger bores. When the mind is exported as a new version, the shell is printed again from its weights. Snapping a disc into a seat is weaving a concern.

3 · Hubs and spokes

Twelve pointcuts on twelve spokes.

Each disc wires to the hub board under the nearest large disc. A hub drives about twelve plungers and reads their sensors: it is where the discs' joinpoints are gathered, a pointcut in matter. Twelve aluminium spokes carry load, heat, power and the CAN-FD bus to the centre.

4 · Power and the brain

Four packs around a Jetson.

Eight 21700 cells in four symmetric packs keep the centre of mass at the centre; the body turns as one, so there is no slip ring. On the carrier sits a Jetson Orin Nano. The aspect net runs here, and the mind is what it learns online.

5 · Fully apart

Every part has a name in the theory.

Disc, hub, net: concern, pointcut, aspect. Nothing here is a second mind beside the net. The gait is an aspect woven at the pointcuts, and a version of the mind is a shell you can hold.

6 · Inside one disc

A plunger, a coil, a sensor.

One mid-size disc, taken apart: a flat cap with a flush light-sensor window, a plunger in a PTFE-lined bushing with an O-ring at the mouth, a return spring, a voice coil in a steel yoke, a Hall sensor that reads the stroke, and six wires to the hub. Six millimetres of travel is the whole gait.

Why a body

A way to see the technology underneath.

OpenJelly's agents are attentionware: a mind made of concerns, woven into aspects, read, versioned and rewritten on evidence. On the mind page that is a sphere of light. Transphere is the same structure in matter, so every term of the theory has a part you can point at.

The trading agent and this body are two instances of one theory. Nothing here is a second mind beside the net: the discs are concerns, the hubs are pointcuts, the gait is an aspect woven at them.

Physics

It moves only by pushing the ground.

A disc extends six millimetres along its own normal. Only the one or two discs behind the contact point can still reach the ground; when they push, the body tips over its contact and rolls one step. Rolling, backing, turning and the small hop are all that gait. Every other motion you see is gesture: discs in the air can only change shape, never move the body.

The same principle drives cable-actuated tensegrity rollers; the difference here is that each push is a single discrete plunger, and the plungers are the concerns.

Boundaries

What we have not built.

This page is a concept render. No prototype exists, the gait has not been simulated, and the six-millimetre stroke makes the body slow and flat-ground only. Transphere is not a product and has no date. It is here because it shows, in matter, what the mind page shows in light.
