The snake-arm works by actuating steel cables, much like the human spine works. The strength and accuracy of the arm is limited by the tensile strength of the cables, the rigidity of the segments and their joints, and the actuators on the back. You seem to use electric motors for the actuators. Are there plans on releasing a version where the actuation is done by pneumatic motors, for higher strength and accuracy? I assume it would be rather costly. The reason I ask is, because the arm seems a bit jittery. Unless you compensate for that at the head with some sort of alignment like a chicken-head, I see this jittery producing uneven sealant, which isn't a problem with the current hydraulic arms.
