A robotic surgical system includes a surgical instrument and a robotic surgical assembly. The robotic surgical assembly defines an instrument opening and includes a floating plate and a drive assembly. The floating plate is movable between an extended position and a compressed position. The surgical instrument is laterally receivable in the instrument opening of the robotic surgical assembly while the floating plate is disposed in the compressed position. The floating plate is movable to the extended position to couple the surgical instrument to the robotic surgical assembly while the surgical instrument is received in the instrument opening of the robotic surgical assembly.
