The project will involve research on court between a real player practising a variety of shots and technical aspects of their swing, a motion tracking sensor attached to the squash racket to monitor swings and speeds of hitting the ball, and a robot receiving this data and interpreting what coaching feedback to provide.
The project is being led by scientists from the National Robotarium, hosted by Heriot-Watt University.
The research facility is part of the Data-Driven Innovation initiative and is supported by £21 million from the UK Government and £1.4 million from the Scottish Government through the £1.3 billion Edinburgh and South East Scotland City Region Deal
This is a 15 year investment programme jointly funded by both governments and regional partners.
The robotic coaching project will be delivered in collaboration with industry partner, RacketWare, using its motion tracking sensor and interfacing technology to translate a player’s data to the robot.
Twelve coaching strategies have been developed from observing one-to-one training sessions between real coaches and players.
Based on the sensor’s data, the coaching strategy programming will enable the robot to give instructions about what the player should practice next, using hints and tips and positive reinforcement. This will imitate live coaching experience.
Martin Ross from Heriot-Watt University explained: “We want to discover if robotics can complement and support the activities of a human coach, bridging the gap between in person coaching sessions when an individual sportsperson is conducting solo practice.
“Robots have been used in other sports, but we believe this is a world first for squash coaching. We are looking forward to sharing results on whether a robot can improve different aspects of a player’s game and increase their motivation for solo practice.”
UK Government Minister for Scotland Iain Stewart said: “This is a superb example of how robots can help us improve our learning in different areas of our daily lives. Innovations like this mean more and more people are able to access support for their health and wellbeing.
“The UK Government is investing £290 million in Data Driven Innovation in Scotland as part of its £1.5 billion City Region and Growth Deals commitment, helping communities to build back better from the pandemic.”
Finally, Dr Paul Mellor, founding director of Racketware, added: “Solo practice is typically used by professional level players and committed rank amateurs.
“Research shows that it increases the skill and motivation levels of all abilities of players. A coaching session is typically £40 per session with an estimated 10-20 coaching sessions required to make progress. It’s expensive, especially if you’re committed to improving your game.
“That’s why we’re excited about this project. It has the capacity to push the frontiers of how motion sensor technology can be applied to racket sports and explore the area of robotic coaching with motion sensor data to develop products, like ours, that make squash coaching accessible to more people.”
Testing started in July at Oriam, Scotland’s national performance centre for sport, based at Heriot-Watt University’s Riccarton campus in Edinburgh. The project will be completed in March 2022.
