I am long on Titan, but I believe a distinction and qualifier need to be made whenever making a statement like SPORT "technology" will be a game changer.
The SPORT platform is not new in that it is an evolutionary outgrowth of the daVinci "console" platform; the difference being primarily that it uses "snake arm efectors". Those articulating arms and the control system they are moved by (and later hopefully haptically enhanced with) are the difference. Footprint, cost, etc., of SPORT can and will be matched by next generation daVincis, I am sure, if the market demands that.
So the bottom line for me in regards to the success of SPORT will be the technological feasibility of the articulated effectors and their control. They are not simple mechanisms; look at the patents. Effective control does not appear simple either. Robotic wristed joints appear to be far simpler solutions.
We have seen the arms demonstrated in rather simplistic videos, but their durablity, dexterity, ease of control, etc. are far from known to us investors. The continued development of that technology is an issue apart from SPORT's use of them and maybe even beyond that of Titan/Ximedica. Big money is required to advance this technology in lockstep wth surgical need.
