Siege EnginesThey know quite a lot about robots and computers but University of Greenwich engineering undergraduates needed rather more traditional skills when they were challenged to design their own siege engines.

More than 120 students are working in groups to build the engines, which will be put into action next month at Fort Amherst. The Chatham-based fort was originally designed to defend the area against a Napoleonic invasion.

The project is being led by Dr Raj Bhatti, Principal Lecturer, who oversees the Faculty of Engineering & Science's integrated first year programme.

The siege engine project has been great fun and I'm looking forward to seeing which designs work best when the teams start competing," he says.

"Our first year brings all our engineers together in disciplines from civil and computer engineering to electrical and electronic, and from industrial and mechanical to design and innovation," Dr Bhatti adds. "They all tackle the basics of all the disciplines before specialising in their second year."

The 20 siege engines will be tested for target accuracy, speed of loading and the distance they can project a large ball of ice.

Students researched the strengths and weaknesses of different engine designs, finalised their plans and tested their concepts with a working scale model. They were then challenged to build their siege engine no larger than would fit in a one metre cube.
