Robotic accuracy tested in kick-off with
All Black great
A robotic leg developed by Massey University engineers will try to out-kick former All Black Andrew Mehrtens as part of an innovation showcase during Rugby World Cup next month.
The man-sized, muscular metallic leg might also upstage other players who have had less than consistent results in getting the oval ball over the goal posts in Rugby World Cup matches to date, says mechatronics lecturer Associate Professor Johan Potgieter.
“We know ball design is not to blame when it comes to goal-kicking accuracy, so we reckon our robot will be able to show what consistent goal kicking really means,” he says, referring to Rugby World Cup goal misses, including by England player Jonny Wilkinson, which have made kicking accuracy a hot issue.
The robotic leg, modelled on a man of 95 percentile optimal physical health, was designed and built at the School of Engineering and Advanced Technology in Albany. It is one of two made by Massey engineers (the other is at the Manawatu campus), with a third made at Canterbury University. The trio of robots will be tested at Victoria Park, Auckland, on October 10 against legendary first five-eighths Andrew Mehrtens, as a precursor to the launch of the inaugural Robotics World Cup at The Cloud on Queen’s Wharf from October 11 to 13.
Dr Potgieter says the challenges of making the solid aluminium life-sized leg, which is joined to a mannequin, centred on getting the anatomy and movement accurate through kinematic design and computerised modelling. He is confident the leg is a worthy match for Mr Mehrtens. “We’ll just have to be careful not to hit the Sky Tower!” he says.
Challenge organizer Chris Hamling, national manager of Kiwibots New Zealand which runs VEX Robotics competitions in schools and the first ever Robotics World Cup next month, says the robots will take drop kicks at a goal from various angles and continue until a winner is declared.
“We’ll start off as if a try has been scored directly between the posts and then the player and robot operator will go to the left and right of the post at certain intervals. Whoever converts the highest number will be the winner.”
The robotic leg from the Albany campus is powered by pneumatic hoses, which are controlled by a Siemens XYZ programmable logic controller. It was made with the help of three visiting French engineering interns from Ensil, a state-owned advanced engineering school in Limoges, and local students. The project has enabled students to adapt knowledge and skills they learn through engineering and design to the specifics of a kicking robot, says Dr Potgieter. Robots like this one could be used in the testing of sports equipment such as rugby balls, he says.
The robots will be on display during the Robotics World Cup as part of the Rutherford Innovation Showcase at The Cloud featuring New Zealand’s information technologies and high-tech industries.
Using the American-based Vex Robotics game model launched by Massey University in New Zealand in 2008, the event will involve university and high school teams from around the world and New Zealand designing, building and maintaining robots that compete in a game of speed, strategy, skill and adrenalin.
Fiji captain finishes degree in nick of time
Massey student and Fiji rugby captain Deacon Manu landed in Auckland this week to lead
his team in final preparations for the Rugby World Cup.
The 32-year-old has completed his Bachelor of Business Studies (Management) degree in the nick of time – handing in his last assignments a week before training commenced for the pinnacle of his sporting career.
Mr Manu says it fitted nicely into the time frame for this year. “Within a week of handing in my two assignments I flew out to start preparation for the Rugby World Cup.”
Mr Manu enjoyed a six-year career with the Chiefs, Blues and Waikato, before moving to Welsh side Llanelli Scarlets in 2006. He says he enrolled at Massey because of its reputation for distance learning.
“The fact that I could be living overseas as a professional athlete in a fickle sports environment gave me the flexibility to change my location if I changed clubs, without compromising my education,” he says.
“Whether or not you are a professional in sport, education and up-skilling is vitally important, as you are always one injury away from not playing rugby again.”
Mr Manu, who has now played more than 100 matches as prop for the Scarlets, expects Fiji to make it through to the quarter-finals, as they did in the last tournament.
“But we are in the pool of death and it provides us with more challenges than the previous world cup,” he says “Grouped with South Africa, Wales, Samoa and Namibia is a formidable pool but we need to qualify to enable us to replicate past achievements. Once you make the play-offs anything can happen and usually does.”
Mr Manu says it is tough for all island teams
to prepare as players are dotted around the world – Fiji’s 30-man squad includes 21 overseas-based players. But he says the political situation is not
a factor.
“Fortunately as players we need to control everything on the field and don’t get caught up with the politics off it. We are here to make Fiji as a nation proud and the only way as players we can do that is though being successful on the field.”
Mr Manu says the sports and psychology papers he studied in particular have helped him to become a successful leader.
“Having a captaincy role for my overseas club and for Fiji is important to me and, although leadership growth is gained by on field experiences, it is important for me to have the knowledge and insight that I have learning in my courses at Massey University.”
Mr Manu says his long-term goal is to work in environmental management, specialising in marine stability. “A far cry from the rugby field but something I have always wanted to do growing up,” he says.
