Realtime Robotics CEO Discusses Funding, Making Industrial Robots Safer, and Ease of Use

Peter Howard, CEO of Realtime Robotics, discusses the company's Series A funding, its technology for making industrial robots safer, and relevant applications.

Realtime Robotics' technology is designed to make industrial robots easier to program and more reactive to people.

Ease of use has been a mantra among robotics vendors in the past few years as they seek to expand adoption. Sensors and software have proven to be the “secret sauce” in automating new tasks. Realtime Robotics Inc. has developed proprietary motion-control technology to enable industrial robots to collaborate with human workers. Yesterday, the company announced completion of a $31.4 million Series A round.

Realtime Robotics, which was founded in 2016, said it plans to use its funding to accelerate product rollouts. The Boston-based startup is a resident member of MassRobotics, an organization dedicated to growing the Massachusetts robotics ecosystem by helping innovators and entrepreneurs.

Peter Howard, CEO of Realtime Robotics, responded to the following questions from Robotics 24/7 about the funding and his company's technology and plans:

How much is Realtime working with investors Omron or Toyota?

Howard: We work extensively with Toyota, which has been a hugely supportive investor from our earliest days. Our business interactions with Omron are at an earlier stage, based on their later investment.

Don't most autonomous mobile robots (AMRs) and collaborative robots already have collision-avoidance systems? What does Realtime add?

Howard: AMRs have collision-avoidance systems that are well-developed and reliable. They are based on 2D sensors that can sense things like people’s legs, at a height above the ground somewhere around midway up the shin, and the AMR either stops—common—or attempts to steer clear of the obstacle—not common.

Cobot arms do not have collision-avoidance systems. They are designed to sense when they do collide with something to stop as quickly as possible. Safety guidelines limit how much power and force they can impart to the thing they hit, to avoid causing serious pain or injury to people.

Practically speaking, this means they can only carry relatively light objects, and they must move much more slowly than industrial robots, limiting their economic viability.

Our solution is focused on industrial robot arms. It is based on collision avoidance utilizing both 2D and 3D sensors and adapting the robot’s motions so that they proactively avoid unacceptably close proximity to people and of course collisions, while still accomplishing their assigned tasks.

This task is way more difficult for a six-degree-of-freedom robot arm moving through three-dimensional space than for an essentially two-dimensional AMR in essentially two-dimensional space, and enabling this is the crux of our technological breakthrough.

Can you briefly explain how Realtime Robotics' motion-planning technology works at scale?

Howard: Realtime Robotics’ AI-driven technology autonomously choreographs all robot movements, allowing multiple robots to work collision-free side by side. Essentially, a universal translator that removes the need for robot brand-specific programming experts, enabling companies with smart automation to reduce costs and increase productivity.

With Realtime’s platform, workcell implementations become significantly less complex and consequently less expensive, lowering the bar of automation and allowing manufacturers to automate a broader range of tasks more quickly and cost-effectively. See our technology overview video.

The functionality is provided in deployment by inserting an industrial PC [IPC] with our special hardware and software on-board into the workcell network, logically connecting our IPC to the robot controllers and the task sequencer—PLC [programmable logic controller], pick system, or another controlling device.

The task sequencer issues very simple sequenced commands to our IPC to take each robot to its next location so that the task can be completed. The task sequencer does not have to contain any low-level code or drivers to actuate the robot, and it does not need to be concerned about the real-world limitations of each robot controller, hardware, or programming language. We take care of all of these on our side.

Do you have any early users or specific use cases that you can cite? 

Howard: Currently, we have well-developed traction in three vertical segments:

  1. Automotive welding and painting, where we decrease robotic system lifecycle costs by upwards of 50% while increasing throughput rates by 10% to 30% with our RapidPlan autonomous path-planning product.
  2. Mixed-case palletizing, where we increase throughput rates by 20% to 40% through autonomous path planning for multiple robots, and massively decrease error driven down-time through closed-loop monitoring of the actual build to prevent time-consuming crashes between robots and things that may have shifted on the pallet after placement.
  3. Digital twin simulation of the robotic component of automation systems, where we provide autonomous path planning for up to 16 simultaneous robots without a single line of manually written code to coordinate interlocks or create interference zones, saving 80% to 90% of the normal programming time.

Is Realtime Robotics hiring? What's your current headcount, and how many positions are open?

Howard: We are hiring, currently around the 60-person mark, and we expect to hire an additional eight to 10 team members before year's end.

What's the next milestone in developing your collaborative technology?

Howard: The short-term milestone is obtaining signoff from our chosen regulatory body that our architecture is compliant with the relevant standards, which will signal that we can proceed to implementation and final certification to the standards.

We have spent the past three years studying various architectures to keep robots productively moving in real-world customer use cases, and we will continue to refine the offering as we move toward certified releases.
