I've been looking for this one for years now. I saw it as a kid in the eighties. I thought it was on NBC and seem to think it was around the same time as Misfits of Science but it was a one-time TV movie. I have found nothing about it though. The story I remember in bits and pieces but here it goes.
There are two scientist, one man and one woman. I don't remember if they are ex-boyfriend and girlfriend or if she is part of his lab for some reason. She is working on making a robot and he is working on teleportation. I believe everyone thinks he's just a failure and a crackpot though. The robot she is building is on the teleportation pad and he uses the other one and teleports to where the robot is. He's really excited and she is upset because her robot is gone. It turns out that he somehow combined with the robot and he starts to become a cyborg. The more he uses his powers the more machine he turns into and his robot parts glow blue.
Here are other scenes I half remember. He is jogging and his legs glow blue and then he has robot legs. Towards the end he is swimming in the ocean and he kicks off his shoes but the metal in his body is dragging him down.
