Dorset, England is known for their large woodlands, and Hooke Park- being 50 acres of woodland, is Dorset’s biggest one yet. Located just north west of Dorchester, Hooke Park’s woodlands mainly consist of 2 species of trees that were planted from the 1950s. Their plan is to have over 15 species that are durable and strong in 50 to 60 years so they can provide a product for the future.
Hook Park is a commercial run forest for timber, and one of the biggest problems they face is a lot of their timber is of variable quality; it is bent, forked, or not suitable for the straightness needed to put through a saw mill. That means that a large portion of their timber ends up being sold as fire wood instead of construction timber.
Students from London’s architecture school have been living on-site in the woodlands as part of their curriculum and have various building projects starting from simple structures, to complex houses and shelters. The project they’re tasked with this year is to take the bad trees; the trees that are firewood quality, and make a whole building out of it.
The students start off by wandering the forest, taking photographs of about 200 trees, and then create a preliminary design. Once they find and choose the ones they want to use, they 3D-scan the wood to create a geometry, which is then used to program their robot using Robotmaster®. Overall, their project building will be made up of 20 forked tree trunks. Using the scanned 3D image of each unique tree, the robot cuts the joints needed to fit them together during the final construction.
The host of the BBC program was watching the Kuka robot programmed with Robotmaster milling into creation precise grooves and angles on the forked tree to fit perfectly amongst all the other forked trees, and was in awe by what he saw. He said “It’s such an odd relationship going on in there, with something that is grown so naturally and so beautiful, it’s being fashioned by something so futuristic”.
Robotmaster is dramatically simplifying the complex milling processes that the students need, and is substantially reducing the overall time needed to program and mill since the process has to be repeated over 20 times, and each time having their own unique complex path.
