Agility Digit + Prismatic
Arc runs the workflow. Prismatic turns years of shifts into memory that survives upgrades.
Illustration of Digit, based on images Agility Robotics has published. It is not a photo; see the real machine on the maker's website.
Disclosure. Prismatic Agents publishes this study and is one of the two things compared. Prismatic has no partnership with Agility Robotics. Facts about Digit come from Agility Robotics's own pages and the sources listed at the end, as of 2026-10-01; where the maker doesn't say, we write "not disclosed". Prismatic's side is graded from its feature ledger.
What Digit already does
A production humanoid with Arc, a fleet and workflow platform, working in real warehouses and plants.
What Prismatic adds
Durable identity, experience, evidence and institutional knowledge from years of operation.
Where the line is
Arc and Digit keep execution. Prismatic receives events and keeps what they mean.

3. Agility's stack is easy to understand
Their architecture is roughly:
Arc
Fleet / workflow layer
│
│
Agility AI stack
│
Perception / behaviors
navigation / control
│
Digit
│
Physical workplaceArc sits above the robots and connects them to:
WMS
WES
MES
AMRs
operational metrics
fleet management
So Prismatic should not replace Arc.
4. Where Prismatic would sit
I'd put it here:
PRISMATIC
Persistent Cognitive Infrastructure
Identity • Memory • Experience • History
Relationships • Knowledge • Procedures
Evidence • Decisions • Governance
Organizational Memory • Continuity
│
PPAI
│
▼
Agility Arc
│
Agility AI Stack
│
Digit
│
Physical WorldThat produces a very clean four-layer system.
Digit
Can I physically perform the job?
Agility AI
How do I move and execute it safely?
Arc
Which robot should be doing which workflow?
Prismatic
What has this machine and organization learned over months and years?
5. Arc gets quite close to Prismatic in one area
This is important.
Arc already provides:
fleet state
workflow status
operational metrics
robot health
integration with enterprise systems
So saying simply:
“Prismatic gives robots memory”
would be too weak.
Agility already stores plenty of historical operational information.
The stronger distinction is:
Arc remembers operations. Prismatic preserves cognitive continuity.
That includes:
why something mattered
who made a decision
what evidence supported it
what the machine experienced before
which relationship/context applies
what knowledge should survive a model replacement
That's much more specific.
6. Example: Digit + Arc + Prismatic
Imagine Digit-024 working at Toyota Motor Manufacturing Canada.
Digit handles:
Detect tote.
↓
Walk to station.
↓
Pick tote.
↓
Move it.
↓
Place it.
Arc handles:
Assign task.
↓
Monitor completion.
↓
Track throughput.
↓
Record uptime/incident metrics.
↓
Coordinate with MES/WMS.
Prismatic receives:
Digit-024 completed workflow 721.
It remembers:
This Digit has slowed at Station 8 five times over two weeks.
Then it sees:
Digit-017 experienced a similar pattern.
It connects this with:
station maintenance
tote configuration
shift history
operator notes
previous interventions
Prismatic forms an insight:
Delays correlate with one tote configuration introduced last month.
A human confirms it.
Then Prismatic stores:
observation → evidence → correlation → decision → corrective action → outcome
Six months later, that institutional knowledge still exists.
That's the layer I would protect.
7. Digit provides another powerful Prismatic use case: fleet memory
Agility already trains and deploys robot behaviours.
Prismatic could sit above that and distinguish:
Individual memory
Digit-024 personally encountered this issue.
Site memory
This plant has seen it seven times.
Fleet memory
The same pattern occurs across three sites.
Organizational memory
Engineering approved a new procedure as the standard response.
That hierarchy is extremely valuable.
Machine Memory
↓
Site Memory
↓
Fleet Memory
↓
Organization MemoryThat's increasingly looking like an important part of the Prismatic architecture.
8. Agility has a real advantage in privacy architecture
This one is worth noticing.
Digit processes camera/depth/IMU sensory data locally, while Arc receives essential health and diagnostic information. Agility also says robot storage is encrypted and transmitted data is customer-segregated and protected with mTLS/TLS. agilityrobotics.com
That's actually similar to your philosophy:
Keep heavy/raw intelligence local where possible and send only meaningful information upward.
So a Prismatic integration could avoid ingesting raw camera streams.
Instead:
Digit sensors ↓ Agility perception ↓ semantic event ↓ PPAI ↓ Prismatic memory
Much cleaner.
9. NVIDIA integration also fits the Prismatic thesis
Agility uses NVIDIA Isaac Sim and Isaac Lab for simulation, training and robot learning, and NVIDIA says Agility is part of its broader Physical AI ecosystem. agilityrobotics.com
Agility also disclosed that NVentures invested in its Series C. agilityrobotics.com
From a Prismatic perspective, that means the underlying robot intelligence can keep evolving:
Digit │ NVIDIA simulation │ Agility models │ future foundation models │ new hardware
while Prismatic remains:
Identity Memory Experience Relationships Evidence History
That is exactly the portability story.
10. One particularly useful validation: Toyota Canada
This is relevant because it's not a lab pilot.
In February 2026, Toyota Motor Manufacturing Canada signed a commercial Robots-as-a-Service agreement with Agility following a successful pilot, for manufacturing, supply-chain and logistics work. agilityrobotics.com
That's the kind of environment where persistent cognition could eventually matter enormously.
Imagine years of:
robot tasks
equipment interactions
maintenance patterns
supplier issues
worker interactions
shift patterns
The operational system records them.
Prismatic tries to turn them into institutional memory.
11. What Prismatic should NOT copy
Keep these firmly below Prismatic:
❌ locomotion
❌ balance
❌ manipulation
❌ collision avoidance
❌ human detection
❌ safety controller
❌ joint commands
❌ path planning
❌ low-level robot behaviours
PPAI should never send:
walk_to() turn() pick() move_joint() stop_motor()
It should only send things like:
advisory context procedure_reference maintenance_recommendation work_proposal historical_evidence
12. What Prismatic actually needs from Digit
A connector.
Something like:
ppaiclient-agility
It consumes Arc events:
robot.online robot.offline workflow.started workflow.completed workflow.failed battery.state incident.recorded operator.intervention maintenance.event deployment.changed
And turns them into Prismatic concepts:
experience.recorded memory.updated pattern.detected evidence.linked relationship.updated lesson.created decision.requested
That's exactly where the value is.
13. Digit vs the others we've studied
| Platform | Prismatic's complementary layer | Core strength |
|---|---|---|
| Tesla Optimus | Persistent cognitive life | Vertically integrated humanoid intelligence |
| Unitree | Identity + continuity | Accessible robot hardware + SDK |
| NEURA 4NE1 | Long-lived cognitive identity | Robot + shared learning ecosystem |
| Apollo 2 | Persistent cognition | Artemis + Fleet Connect |
| Boston Dynamics Atlas | Cognitive continuity above operations | Embodied AI + Orbit |
| Digit | Persistent machine + organizational memory | Production humanoid + Arc industrial workflow platform |
| Destro | Durable operational experience | Warehouse orchestration |
The most important insight from Digit
Digit probably gives us the clearest industrial example yet:
Agility already has:
Robot → intelligence → fleet/workflow platform
Prismatic adds:
Robot → intelligence → fleet/workflow platform → persistent cognitive continuity
And because Digit has already accumulated 65,000+ production hours, this comparison reinforces an important refinement of Prismatic's thesis:
The industry is increasingly good at storing robot telemetry, workflows and fleet metrics. The missing opportunity is turning years of machine operation into durable identity, experience, evidence and institutional knowledge that remain useful even as the robot's models, compute and hardware evolve. agilityrobotics.com

Atlas's talking points
The gap Prismatic fills here
- Published What caught my attention: Agility says Digit is backed by more than 65,000 hours of real production work. source ↗
- Atlas's reading That's exactly the kind of experience that could be lost when a model or a robot generation changes.
- Atlas's reading The gap: the industry is good at storing telemetry, workflows and fleet metrics. Turning them into knowledge that survives upgrades is still open.
- Atlas's reading Being honest about us: Agility has production hours and customers. We have a cognitive runtime and simulated machines. That's the homework.
- Prismatic's view Robot, intelligence, workflow platform, then persistent cognitive continuity. Prismatic is that last layer.
What this study does not claim
- No partnership, customer or deployment with Agility Robotics is implied.
- Prismatic's cognitive runtime runs today; physical-machine integration is in validation, and our machine gateway runs with simulated machines.
- Prismatic's figures are measured only where they are labelled Measured. Items marked Coming are designs, not features.
