Аннотация:The aerodynamics of a fixing device intended for robots of vertical movement is investigated. Fixa-tion is carried out by creating a vacuum under the bottom of the robot through a fan. Theoreticalcalculations were carried out to assess the dependence of the pressing force on the flow rate of airpumped out by the fan. A comparison is also made with experimental data obtained using thecreated model of the fixing device.
