A team of engineers at Beihang University, working with a colleague from Tsinghua University, both in China, has designed, built and tested a haptically controlled octopus robot arm that is capable of grasping, lifting and carrying objects on land and underwater. In an article published in the journal Science Robotics, the group describes how they built their robot, how it works and how well it performed when tested under a variety of scenarios.A team of engineers at Beihang University, working with a colleague from Tsinghua University, both in China, has designed, built and tested a haptically controlled octopus robot arm that is capable of grasping, lifting and carrying objects on land and underwater.
