Abstract:The Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center has been
developing robotic equipment and machinery for highway maintenance and construction operations. It is a
cooperative venture between the University of California at Davis and the California Department of
Transportation (Caltrans). The research and development projects have the goal of increasing safety and
efficiency of roadwork operations through the appropriate application of automation solutions.
This report describes the design and analysis of vegetation cutting attachments for the Automated Roadway
Debris Vacuum (ARDVAC), a tele-robotic litter removal system. This combination of ARDVAC system and
cutting attachments is designed to operate in median divider areas, roadway shoulders, around guardrails, and
on some embankments adjacent to roadways. It is capable of removing, by vacuum flow of air, trash, litter,
loose vegetation and similar materials. The cutting attachments enable the removal of most vegetation found on
the roadside. The machine is controlled from within the safety of the vehicle’s cab, requires no on-site set-up,
operates with controls of minimum complexity, and is a significant solution to the problem of roadway litter
collection and vegetation removal. The development of two general cutting tool attachments and one
tumbleweed removal attachment is described.
