ANT61 Robotics, a start-up based in Sydney, Australia, is revolutionizing the space industry with their autonomous robots. These robots, developed by ANT61, are designed to perform tasks in unpredictable environments where remote control is impossible. By using AI-based control systems and simulation-based reinforcement learning, ANT61 is training their robots to perform complex tasks in space.
Reinforcement Learning: Robots Learning by Trial and Error
Reinforcement learning has emerged as a powerful method for training AI models in recent years. Instead of engineers manually coding movements for the robots, reinforcement learning allows the robots to learn from their environment through trial and error. ANT61 is leveraging this technology to build autonomous robots for space and other dangerous environments. They believe that soon, robotic skills learned through reinforcement learning will surpass human-coded behaviors.
Observations Are Key
In reinforcement learning, observations serve as the data for training the AI models. The more observations the robots receive, the better their control system becomes. ANT61 uses observations produced by the robots as they work independently to solve problems. This enables them to create more efficient and cost-effective robots that can accomplish a wide range of tasks.
Reducing Time and Cost with Simulations
Training robots through reinforcement learning requires numerous iterations in simulation environments. ANT61 uses the Gazebo simulation platform to quickly create simulation worlds. Initially, they ran simulations on a single EC2 instance with a GPU, taking two weeks to complete one training. To speed up the process, they scaled horizontally by adding more servers, each running one robot. However, it still took two weeks to finish each experiment.
Multi-Agent Training for Faster Results
To further reduce the time needed for experiments, ANT61 employed modern reinforcement learning algorithms like TD3 and APPO to train multiple models simultaneously. This involved having multiple robots train in parallel and share their observations and outputs. This way, if one robot learns a new behavior, it teaches it to the rest of the group. By training multiple robots in one simulation world, they were able to gather four times more observations, significantly reducing the experiment duration from two weeks to just four days.
Using AWS for Parallel Training
ANT61 utilizes the Ray library and AWS to create and manage clusters of EC2 instances for machine learning training tasks. Each instance in a cluster trains several robots in parallel, generating millions of observations hourly. With the power of horizontal scaling in AWS, they were able to decrease the experiment time from four days to just four hours, all at the same cost.
Cost Optimization using EC2 Instances
Initially, ANT61 used GPU-accelerated g4dn.xlarge instances for their simulations and training workloads. However, they realized that most of the resources were spent on CPU-intensive tasks, making the GPU unnecessary. Through optimization, they discovered that m5.large instances offered the best cost per observation compared to other instance types. The m5.large instances were five times less expensive than g4dn.xlarge.
Spot Instances for Cost Reduction
By utilizing Amazon EC2 Spot Instances, which provide up to a 90% discount compared to On-Demand prices, ANT61 reduced costs by 62% compared to On-Demand EC2. Spot Instances are ideal for ANT61 as their simulations do not store persistent data on worker nodes. Instead, observations are sent to the head node in real-time.
Efficient Robot Training with AWS
ANT61 has efficiently scaled their robot training process with AWS. They now run multiple experiments daily, obtaining results in minutes instead of weeks, and at a significantly reduced cost. Their machine for generating observations has great potential to scale further. While training robots in the real world is ideal, simulation-based training on AWS offers a cost-effective and time-efficient solution.
Looking to the Future
ANT61 continues to innovate and improve their robot training workflow with AWS as a crucial tool in their arsenal. Training robots in the physical world may be costly and time-consuming, but powerful simulation software, like NVIDIA’s Isaac Sim, offers hyper-realistic environments. Perhaps, in the future, a fusion of reality and simulation will provide the best of both worlds, enabling even more advancements in robotic training.
