Two bionic innovations were last week displayed in South Africa for the first time.

The Festo SmartBird, which replicated the wing motion of a Herring Gull in robotic form, and the BionicOpter, a flying robot based on the dragonfly, took flight at the nineteenth World Congress of the International Federation of Automatic Control (IFAC), in Cape Town.

Delegates to the IFAC conference witnessed the SmartBird and the BionicOpter take off and fly across the plenary hall at the Cape Town International Convention Centre.

Festo believes the SmartBird was the first energy-efficient technological adaptation of a biological creature.

The lightweight, yet powerful, bird was capable of reaching speeds of 25 km/h. Its wings beat up and down and could also twist at specific angles. The robotic bird showed the possibilities for energy efficiency through automated robots, said Festo corporate communications head Dr Heinrich Frontzek.
The innovations formed part of the Bionic Learning Network, which took inspiration from nature and created engineered replicas. The network comprised Festo specialists, universities, industrialists, engineers, students and inventors.

“The goal of the network is to motivate, inspire and kick-start innovation,” stated Frontzek.

The BionicOpter featured wings that could move independently, allowing it to slow down, accelerate quickly, fly backwards and make sharp turns.
“It’s able to fly like a plane, glide like a glider and hover like a helicopter,” Frontzek told delegates at the conference.

The highly complex BionicOpter had a wingspan of 63 cm and a body length of 44 cm, yet weighed only 175 g. The lightweight construction of the artificial dragonfly was achieved by reducing material use and the function of many components in an extremely tight space.

The wings consisted of a carbon-fibre frame and a thin foil covering, while the highly integrated system could be operated with a smartphone.

“We can learn a great deal from nature. Learn-ing from nature will increase the automation of tomorrow,” Frontzek asserted.

Other innovations from the Bionic Learning Network included the Bionic Handling Assistant, based on an elephant’s trunk, as well as the Bionic Kangaroo, which Festo believes holds important lessons in the way it jumps and is then able to recover, store and retrieve energy efficiently on the next jump.

“From these bionics, we learn new approaches for automation,” noted Frontzek.

Developments in the field were seeing more functions integrated into smaller spaces, and components getting smarter.

“Automation control is fascinating. It brings so many fields together and gives engineers great scope,” said Festo sub-Saharan Africa MD Richard Teagle.
