The installation of the high-altitude curtain wall is mainly completed manually with simple mechanical assistance. The construction process is characterized by high labor intensity, high risk, low efficiency and low quality. To improve the automation and intelligence of curtain wall installation, improve construction efficiency and reduce labor intensity, a mobile manipulator for curtain wall installation is developed. Firstly, the curtain wall installation process is analyzed. Secondly, kinematics modeling is established, and the forward and inverse kinematics are analyzed and solved. Finally, the experiment is carried out to complete the tasks of grasping, rolling over and transporting stone, glass, ALC plate and other dense and semi-dense materials.

Recently, old and dilapidated infrastructures such as bridges, chimneys and tunnels have become very serious in Japan. Inspection of the infrastructure was done by climbing the ladders that were set up. However, the inspection becomes dangerous as it is necessary to climb into very high areas and unpredictable weather and conditions. In this study, a lightweight inspection robot that can climb ladders in adverse weather conditions was proposed and tested. To grasp a ladder pillar without hurting, the wrapping motion is required. Therefore, the flexible robot arm that can grasp the ladder pillar while approaching and release it while going away was also proposed and tested. The automatic ladder-climbing inspection robot that consists of two pillar grasping flexible robot arms and a lifting robot arm was proposed and tested. The control system of the robot, driven by four on/off valves and an embedded controller, was also constructed. The ladder climbing experiment using the tested robot was carried out. As a result, it could be confirmed that the robot can climb up and down a ladder with soft gripping the ladder, and the soft robot can be also operated by using only four valves.
