Tunnelling and underground construction specialist Hypertunnel has unveiled the robotic delivery system at the core of its new tunnelling method. The Hyperbot robots can transport cartridges of construction chemicals through horizontal directional drilling bore pipes to 3D-print tunnels. Hypertunnel said "this scalable and modular approach will make tunnel building, repair, enlargement and monitoring, faster, cheaper, safer, more environmentally friendly and involve much less project risk than current tunnelling methods". The concept is currently undergoing advanced testing.
