What are the latest developments in AI?
Here are some of the
latest notable developments in AI as of early 2024:
- Large language models like Anthropic's
Constitutional AI assistant Claude continue to advance quickly,
demonstrating increasingly sophisticated natural language capabilities.
Models are growing larger to handle more complex reasoning and knowledge
tasks.
- Self-driving vehicles continue gradual
progress, with companies like Waymo and Cruise Automation expanding their
driverless taxi services to more cities. However, safety drivers still
supervise many trips. Approvals for fully autonomous operations are still
pending regulation.
- Robotics and computer vision are finding
growing commercial success in warehouse automation and last mile delivery
via drones and robots. Companies like Amazon and FedEx are rapidly
adopting these technologies.
- AI algorithms matched human experts on
recent medical imaging tasks. Though real-world healthcare implementation
remains early and building full trust in AI diagnosis is ongoing work.
- Generative AI models saw breakout interest
from tech companies and users. Models like DALL-E 2, Stable Diffusion and
GPT-3 produce synthetic images, text, code and more from text prompts at
an increasingly impressive and accessible level.
- The use of AI in enterprise analytics,
financial technology, marketing technology and more business applications
continues growing steadily. Automating business decisions and workflows is
a major driver of AI investment.
The next big
milestones on the horizon seem to be around human-like chatbots, safe
autonomous vehicle operations opening up, and increasing automation in stores,
homes, offices and factories using adaptive robotics and embedded AI. But
unexpected new advances and applications continue rising rapidly in this
exponentially progressing field.
As time and motion study
were the blood of efficiency in productions, can we rationalise that the AI is
a new complement/replacement?
AB
Yes, that's an apt
analogy. Just as time and motion studies aimed to analyze work processes to
improve efficiency, AI stands to both complement and potentially replace
certain human tasks and workflows through increased automation.
Specifically, AI
systems can now perform efficient pattern recognition, data analysis,
prediction, natural language processing, decision support, and content generation
at high volumes - roles often previously filled by human analysts. This allows
businesses to:
- Gain deeper insights from data for
optimizing processes
- Automate complex, repetitive, or dangerous
jobs previously requiring human workers
- Free up human workers to focus on more
high-value creative, interpersonal, oversight or exception handling tasks
- Enable new data-driven services not
previously feasible
- Scale up operations significantly without
expanding human personnel
The way many factories
now have 'smart' computer-controlled manufacturing equipment, businesses and
industries of all types are augmented or disrupted by ever-smarter AI
assistants. AI promises to play an increasing behind-the-scenes role in driving
productivity, similar to past advances like the computerisation of processes
via spreadsheets, databases and automation software. The boundaries of machine
versus human tasks continue to evolve through augmentation, substitution and
creation of new solutions.
Do AI robots communicate
with each other without any pre-set algorithms?
AB
No, at least not yet
with current technology. All communication and behavior in AI systems,
including robots, originates from some combination of pre-programmed logic and
machine learning over time based on data or experience. There is currently no
evidence that AI robots have achieved truly open-ended unsupervised
communication.
Some key reasons AI
robot communication still depends on pre-set algorithms:
- Language models require training. Even advanced
systems like Claude learn language from analyzing billions of
human-written examples first to understand how to respond or converse
realistically. Without significant built-up language exposure,
communication is meaningless or minimal.
- Most AI robot behavior today follows some
form of reinforcement learning algorithm. This means that initial
behaviors and goals are pre-defined by the developers. Beyond that, the AI
agents learn optimized actions based on rewards in test simulations or while
interacting with real environments. But the foundation is seeded learning
guided by algorithms.
- There are currently no fundamental general
"common sense" or social learning frameworks in AI analogous to
human cultural knowledge. So for robots to hold open domain
multi-participant conversations today still requires relying heavily on
scripted responses geared to predictable use cases.
- While techniques like emergent
communication between cooperative AI agents in games exist, translating
that into real robots collaborating using intuitive learned signals
remains an active area of research rather than practical reality.
In future, more
flexible cross-domain social learning, explainable collective intelligence, and
shared communication protocols could perhaps enable AI robot swarms or
societies exhibiting their own novel exchanges. But granting arbitrary
communication flexibility to AI remains contentious around potential misuse or
misunderstandings. The field advances cautiously.
Are robot’s modules
designed?
AB
Yes, most robots are
designed using a modular approach, where different components and functions are
separated into distinct units that can be put together in different
configurations. Here are some examples of common modules in robot design:
- Actuators: These modules generate movement
and force, such as electric motors, pneumatic actuators, and hydraulic
pumps. Different actuators allow robots to move around, apply pressure,
grip objects, and more.
- Sensors: Robots use sensors like cameras,
LiDAR, proximity sensors, and pressure sensors to detect and map their
surroundings. Separate sensor modules feed data to help guide robotic
actions and awareness.
- Controllers: Controller units’ house core
computing processors as well as interface I/O ports to integrate signals
from other connected modules. They run operating code and algorithms that
command robot behavior.
- End effectors: End effector units are
replaceable modules mounted at the ends of robots to enable specialized
behaviors - such as grippers for grasping, drills for construction,
mounted guns for defense uses, etc. Having switchable end effectors allows
more flexibility.
The benefit of this
modular paradigm is that different standardized module components can be mixed
and matched to create many specialized robot configurations from common parts.
These modules are designed to be easy to integrate using standard
inputs/outputs while encapsulating core functionalities. This provides
flexibility when building custom robots for different applications and allows
upgrading certain modules without having to completely redesign the robot from
ground up.

What are the level of
tolerance in each module?
AB
The tolerance levels
in robot modules can vary considerably depending on the type of module and its
function. However, here are some general guidelines:
Actuators:
- Electric servo motors usually have
tolerances around 10-20 RPM speed variation and torque/power output
decreases gradually rather than failing outright.
- Hydraulic actuators usually have tighter
5-10% tolerance for output pressure/force deviations.
Sensors:
- Proximity and vision sensors can cope with
20-30% variation in detection ranges or slight image defects before
performance degrades sharply.
- Force sensors and encoders aim for 5-10%
monitoring accuracy tolerances before giving faulty controller signals.
Controllers:
- Computation components like CPUs require
voltage input regulation within 5% and thermal throttling outside 20-30C
operating range.
- Network chips sync communication with
10-100 MHz frequency tolerance and can fail if either excess bandwidth or
electrical noise overwhelms protocol error checking.
End Effectors:
- Grippers tolerate wider 20-40% variation
in applied grip force, but fine manipulation requires better than 10%
force control.
- Tool connectors build in modular
flexibility coping with weight, center of gravity changes up to 20% on
attachments.
In safety-critical
applications, redundancies are built-in so failure of one module stays within
acceptable risk limits. But in general, most modules are designed to degrade
gradually rather than outright fail due to subtle manufacturing differences and
wear-and-tear over product lifetime. The modular interfaces help enforce
stability by capping downstream propagation effects.
Can a robot repair
another robot - like a maintenance supervisor?
AB
Absolutely, robots
with the right capabilities can repair and maintain other robots. Having robots
service robots offers a few major advantages:
- No need to schedule human technicians for
simple maintenance, troubleshooting or component swaps. The supervisory
robot can handle basic upkeep issues independently in between major
overhauls.
- Mobile service robots can navigate to
broken down robot locations for on-site diagnoses and repairs. This avoids
downtime moving heavy industrial robots back to central workshops.
- Specialized multimodal sensory
capabilities (cameras, NDE sensors like ultrasound or X-ray) can detect
failures human technicians might miss through complex inspections.
- Standardized modular designs with
quick-connect interfaces can enable easier changeovers of common wore-out
parts (motors, batteries, compute boards) by robotic arms/grippers vs
human hands.
- Robots don't risk injury hazards accessing
dangerous confined spaces human technicians can't easily fit in or require
extra safety precautions before entry.
While rigorous designs
for resilience, plus scheduled rebuilds and software updates mitigate issues,
having robotic capabilities handle at least tier-1 maintenance reduces
operating costs. It also frees up human technicians to focus on the trickiest
debugging, custom machining/welding, reprogramming challenges better suited for
adaptable human cognition. The aim is optimizing the strengths of both humans
and robots.
DARPA's recent ARM
hardware program demonstrated early successes of mobile supervised autonomous
robots assisting human warehouse technicians install parts, inspect items
closely, retrieve tools or move heavy objects - showcasing the
repairs/maintenance robot helper concept proving out. As robot deployment
scales up in factories, expanded robotic self-service abilities will likely
emerge to keep everything running smoothly.
Write a summary for
this session.
AB
Here is a summary of
our conversation:
We discussed the
latest developments in AI technology, including advances in large language
models, self-driving vehicles, warehouse robotics, medical imaging algorithms,
and generative AI models. I explained how AI is becoming analogous to past
efficiency improvements like time and motion studies, complementing and
automating human roles across many industries.
We talked about some
of the current limitations in AI robot autonomy - notably that robot behavior
and communication still depends completely on human-programmed algorithms
rather than open-ended learning. I outlined common modular components used in
robotics like actuators, sensors, controllers and end effectors. These allow
flexible reconfiguration and upgrading of capabilities.
Regarding tolerance
levels, I provided typical ranges for variation and degradation that various
robot modules can handle before performance is impacted significantly. Finally,
we discussed the emerging concept of robot maintenance supervisors that can
conduct their own inspections, repairs and parts swapping to reduce human
technician burdens and downtime in robot fleets. The summary touched on both
present progress and future possibilities at the intersection of AI and
robotics.
