Six-legged hexapod robots can navigate rugged terrain and access places human workers cannot.
In 1977, George Lucas’ Star Wars introduced us to R2-D2, an intelligent bot that embodied modern assistive robotics: he could anticipate needs and perform a number of tasks with minimal instruction.
Almost 40 years later, assisted robotics offer game-changing advantages to manufacturing, and we’ve been canvassing Australian manufacturers to find out how robots can help them overcome current challenges.
Through a series of workshops held in Melbourne and Brisbane, we investigated what manufacturers want and where they envisage using robotics help to solve current problems.
Here, I present Australian manufacturing’s wish-list for robotics.
Robots to make the workplace safer
Australian manufacturers want to use robots to orient, lift and manipulate components so that workers can assemble them with greater precision in manufacturing lines.
The major objective is to reduce occupational health and safety events, compensation claims and lost time from worker absenteeism – though improved product quality is often a bonus.
Robots have established potential to take on jobs that people don’t want to do and really shouldn’t be doing, such as hazardous or highly repetitive tasks that make workers vulnerable to repetitive-stress injuries.
In 2011, Dulux Group installed a robotic system in a Victorian factory to assist workers handling heavy bags of combustible powder which posed a potential respiratory hazard for workers.
The robotic system eliminated occupational health and safety incidents and allowed nine workers to be redeployed from a potentially hazardous and uncomfortable working environment.
Robots to help increase productivity
Australian manufacturers want assistive robots as an active extra pair of hands to increase worker production output.
Robots have been shown to be effective in increasing productivity in industries varying from spray painting, welding, trailer manufacturing and plastic part manufacture – see the video below.
An industrial robot from automation technology company ABB Australia, installed in 2008 has increased productivity and turnover for Brisbane-based Drake Trailers, one of Australia’s largest manufacturers of low-loader and specialist large scale trailers.
The ABB robot helped Drake Trailers lower unit cost while achieving better finish and repeatability. The increase in productivity at the family-owned company translated into an annual turnover of A$45-50 million, while staff numbers doubled within five years.
The spray painting division of Melbourne-based Hilustre Coatings handles a wide range of products, including kitchen cabinets, display panels, shop fittings and automotive components.
The variation in size, shape and product diversity of the one million items processed each year meant that a robot had to be capable of quick and easy transition to cope with the requirements of the facility.
The robotic process installed allowed Hilustre to increase efficiency by about 40%, and reduce the amount of paint per run while increasing the quality and consistency. Lower wastage of paint and solvent has improved economy of the operation.
Improving product quality using robots
Assistive robotics offer lots of opportunity for improving the quality of manufactured products. Australian manufacturers are keen to see this happen through use of real time physical and virtual supervision to improve quality and reduce product rejection rates and waste:
- by reducing time required for inspection and certification through real time capture of quality and compliance data during manufacture
- by improving product quality by reducing misalignment and incorrect assembly of components.
Reducing set-up time and downtime
Assistive automation offers the opportunity to reduce set-up time through automated jig recalibration (to allow a manufacturing process that ability to produce different good), or via virtual capture and replay of processes to identify timesaving opportunities. Virtual manuals allow a rapid response, also reducing set-up time.
Similarly, virtual technologies make expert assistance readily available for problem solving and repairs in remote areas through a computer link, enabling reductions in downtime. They also offer the potential for a shift in business model through sale of virtual services for maintenance.
Ford have been using virtual imaging of vehicles and interiors for some time. The company now plans to simulate the full assembly line production process to improve quality and cut down costs in real world manufacturing facilities.
Ford uses camera technology to scan and digitise real-world manufacturing facilities to create ultra-realistic 3D virtual assembly environments.
Extending workforce participation for older workers
Faced with an ageing workforce, Australian manufacturers are keen to retain skilled employees by using augmentation technologies, such as tele-supervision and tele-operation, to allow employees safe and productive extended working lives, and to facilitate phased retirement programs.
For example, General Electric now uses tele-operated “spiderman” wall-climbing robots for quality inspection of their 90-metre-tall wind turbine towers.
Instead of an inspector standing in a field, stopping the turbine and photographing potential problem spots with a powerful telephoto lens, the robot carries a camera which enables it to take photos of the turbine blades and beam them back to its operator on the ground quickly and efficiently.
If you too would like assistive robotics in your manufacturing business, we’re seeking ongoing input from Australian manufacturers. Send me your thoughts at email@example.com.
