A suspendable crawler-type underwater operations robot for extremely soft ground comprises a traveling mechanism (103). The traveling mechanism (103) is a crawler-skid composite structure. A mud skid structure (105) is fixed on each of two sides of a crawler (106). The bottom of the mud skid structure (105) is higher than the bottom of the crawler (106) and has an arched board head (1013). The arched board head (1013) is provided with a board water spray device (1015), and the board water injection device (1015) sprays water forwards. During operation of the traveling mechanism (103), the arched board head (1013) pushes water downwards and inwards, and the pushed water and the sprayed water together form an aqueous film at the bottom of the mud skid structure (105), thereby reducing travel resistance and achieving stable travel on extremely soft ground. The underwater robot is further provided with a propulsion mechanism, a buoyancy adjustment device, and an operation module, and therefore can travel autonomously on the seabed or be suspended in water, and has multiple functions such as automatic fault recovery and the ability to perform fine operations. |
