Battery decisions for mobile robots are critical for achieving power autonomy, but they can be complex:

· How much capacity is needed?
· Where can I put the battery?
· What is the best charge method?

In this session, attendees will learn the answers to these questions and more. Detailed information for designers who need reliable portable power for mobile robots will be provided. Additional topics covered include system considerations such as non-motive loads, battery placement issues, and how to design for re-generative braking charging. Also discussed will be wired and wireless charging pros and cons, plus the trade-offs between short, quick charging and once-per-shift charging methodologies.

Many types of robots can leverage 3D LiDAR data to gain situational awareness in real time. This awareness is essential to perform required tasks but also to enable market adoption. However, effectively using LiDAR data in real time is complex and expensive. The lack of standards also makes it challenging and threatens to slow adoption. In this presentation, attendees will learn about a new category of LiDAR software – a real-time pre-processing engine – that allows application developers and integrators to use LiDAR data from any hardware supplier and for any application. Real-world use cases and LiDAR recordings will be used to illustrate the practical applications.

For a long time, robotics software development has been forced to make the choice between safe software and fast software. Early on, Scythe Robotics chose a third path: Rust, the new programming language that promised a break from that dichotomy. It was a lonely and bold choice at the time but has paid huge dividends.

Scythe Robotics, a developer of commercial autonomous lawnmowers, will discuss its decision to use Rust and some learnings along the way. It will discuss how it benefited from Rust’s strengths to build a robot software platform that is both reliable and performant, while still enabling high-velocity development. For example, leveraging the best parts of both ROS and Rust is possible with the mature rosrust crate, which allows engineers to make use of existing ROS tools as well as the wider crates.io package ecosystem. Further, directly integrating with other existing C/C++ software is straightforward as well, enabling reuse of proven libraries and device-specific features like compute accelerators and other C/C++ platform SDKs.

Scythe’s rapid progress is, in no small part, due to the strengths of Rust and the confidence it has unlocked for developers to move fast and build things reliably. This talk will be a guide for others looking to oxidize and accelerate their software development process.

In modern robotic applications, space comes at a premium. Power density continues to be a leading factor in robotic applications, although it is often compromised by the cabling and hardware needed to implement the power and control systems. In this session, we will explore how to simplify the design of a robotic joint without compromising performance, reliability, or advanced motion control features that normally come at the cost of bulky cabling and electronics.

Robotics for large-scale fabrication or processing has relied on the ability to realize what is referred to as “coordinated motion.” This enables a robotic arm to work beyond its reach envelope by precise coordination with external axes. These external axes may be linear rails, or rotational axes to extend the working envelop of the combined robotic solution. Mobile robots have also gained in adoption and use, but, even in fairly complex mobile manipulator solutions, coordinated motion is only realized through the connection of the manipulator and the base via an external monitoring device. These solutions also normally make use of a “stop and go” approach in which the mobile base positions itself in a static pose first before the industrial manipulator begins its operation, thus not demonstrating true coordinated motion.

Southwest Research Institute seeks to pursue a coordinated motion solution that will enable richer continuous processing beyond the standard reach of the manipulator without the need to tie together the base and manipulator with an external tracking device, therefore opening a new frontier of industrial mobile robots that currently are not available in industry.

Traditional sensors and navigation stacks have enabled AGVs and AMRs to bring tremendous value to a finite set of indoor material handling applications. But a much broader set of additional applications remains unsolved due to limitations in more challenging environments, including outdoor, indoor/outdoor, spaces with dynamic or repetitive features and where mobile robots must interact seamlessly together with humans. The panelists will discuss how recent technology advances are setting the stage for the next wave of innovation mobile robots and share examples of exciting new applications that will be unlocked.
