In the rapidly changing field of robotics and artificial intelligence, collaboration is the key to pushing the boundaries and opening new possibilities in research. Shadow Robot, a leader in dexterous robotic hand technology is demonstrating this principle through a groundbreaking partnership with Google DeepMind.
Shadow Robot takes a unique approach to collaboration and problem-solving, which has resulted in the development of DEX-EE, a robotic hand that is already transforming machine learning research. This article looks at Shadow’s collaborative methodology and shows how their expertise extends beyond hardware manufacturing, and positions the company as an invaluable research partner in advanced robotic capabilities and artificial intelligence.
Shadow Robot's Collaborative Philosophy
Collaboration is at the heart of Shadow’s engineering philosophy. The team at Shadow prioritizes client needs to make sure that every solution is tailored to meet the specific problems and challenges posed by each client. This dedication to client needs and custom solutions complements the company’s willingness to rethink fundamental aspects of their designs, meaning that the team at Shadow can push the boundaries of what’s possible in robotics.
Shadow’s collaborative approach is based on an iterative development process. By engaging in continuous testing and refinement, engineers at Shadow can adapt designs based on client feedback and evolving requirements. By following this workflow, the company is able to merge academic research and practical applications, building robust robotic hands that can withstand rigorous research.
In their blog post, “Collaborative Working: A Case Study”, Shadow Robot Director Rich Walker captures the company’s philosophy perfectly: “When solving a very general need, such as manipulating objects in the real world, cross-disciplinary collaboration is the only way to move fast enough to build something useful.” The collaborative spirit at Shadow drives innovation and builds strong partnerships, and helps to keep Shadow Robot at the forefront of robotics technology.
The DeepMind Collaboration: A Comprehensive Case Study
The collaboration between Shadow Robot and Google DeepMind began with a huge challenge: DeepMind needed a robot that was capable of enduring long-term, physically demanding experiments as part of their research into generalized intelligence and the role of embodiment in learning. As it was, Shadow Robot’s original Dexterous Hand was not robust enough for the repeated physical impacts required by DeepMind’s learning protocols. To meet this challenge, Shadow and DeepMind needed to work together to find a more reliable solution.
Phased Development Process
The result was a five-year development process to build Shadow’s new DEX-EE hand in collaboration with DeepMind. This project was divided into three phases. At the end of each phase, a usable version of the robot hand was delivered for iterative testing and design changes. Then, the hand was moved on to the next phase to be developed with increasingly complex requirements. The team started with a single finger and refined every element of the design before progressing to the final hand.
Each phase of the development process needed to meet key milestones, including rigorous testing and validation at every stage. By following this iterative development process, Shadow Robot was able to optimize individual components while maintaining a design that was flexible enough to adapt as findings emerged. Gavid Cassidy, head of Product Development at Shadow, noted “Working this way means you can test and refine without being constrained by the overall design.” This approach enabled engineers to isolate any problems with individual components and address them effectively.
Overcoming Challenges
The collaborative project with DeepMind faced significant challenges. One of the biggest hurdles to overcome was to ensure that DEX-EE could withstand the demands of DeepMind’s experiments without compromising data quality. Rich Walker emphasized the importance of adaptability while addressing project challenges: “When we’re working with researchers, we’re always working at the bleeding edge of tech… it’s about being responsive and helping clients develop the things they want to do.”
Throughout the development process, Shadow Robot maintained open lines of communication and worked closely with DeepMind, which meant engineers at Shadow could make adjustments to the scope of the project based on immediate feedback. Shadow’s level of responsiveness strengthened the collaborative relationship and also ensured that each iteration of DEX-EE met DeepMind’s evolving requirements.
Evolution of the Partnership
As development of the new robotic hand progressed, Shadow Robot introduced new avenues for optimization, leading DeepMind to request adjustments in data output levels. To Shadow, this indicated that the project was reaching new levels of innovation, unanticipated by DeepMind. Rich Walker remarked on this achievement: “It’s nice to feel like we were able to exceed their expectations.”
The culmination of this partnership resulted in DEX-EE, a dexterous robot hand designed for functionality, reliability, and versatility, in research applications. Gavin Cassidy reflected on the impact of the project: “This feels like the best example of us working on a customer-led project”.
Future Implications of DEX-EE
Looking ahead, both Shadow robot and DeepMind see vast potential for DEX-EE beyond AI research. The breakthrough technology that resulted from this collaboration is positioned to inspire innovations across industries. According to Rich Walker, “For us, the next step is showing this technology to the world and asking, what can you do now that you couldn’t do before?”
This case study demonstrates how Shadow Robot’s collaborative philosophy brought about astounding technological advancements and established a new framework for future partnerships in robotic innovations.
Shadow’s DEX-EE Innovations
The innovation behind DEX-EE represents a forward step in robotic hand technology. DEX-EE is designed specifically for long-term, physically demanding experiments in machine learning. The hand has a robust construction that allows for extended periods of operation without interruption caused by hardware failure. With these features, DEX-EE demonstrates new possibilities in reinforcement learning research.
One standout feature of the hand is its tactile sensing capabilities. Each finger has hundreds of channels of tactile sensing, including Shadow’s innovative fingertip sensors. These sensors boast hundreds of taxels with an impressive dynamic range. Using this sensory data, research can gather extensive information from dexterous robotic tasks.
Next on the list of innovations is DEX-EE’s precise force control, achieved through high-bandwidth torque and position control loops. This level of control enables delicate and precise fingertip dexterity. The hand can go from fully open to closed in just 500 milliseconds, and can deliver a 10 N fingertip pinch, demonstrating both speed and strength.
DEX-EE is integrated with ROS (Robot Operating System), an open-source framework used in robotics applications in research and industry. This makes the hand a versatile research tool, capable of adapting to the ever-changing needs of machine learning research. DEX-EE’s combination of robustness, advanced sensing, and adaptability is transformative and pushes the boundaries of dexterous manipulation and AI research.
