So this is my situation I'm 3 months into my 2nd year of a Computer Science PhD and I've come to the conclusion that I just shouldn't have started it in the first place.

I did my undergraduate degree at the same university and was approached by my undergraduate thesis supervisor to do a PhD. My department does mainly theoretical work which isn't really my taste, robotics has been a hobby of mine even before I started university so I wanted to do something more practical. It turned out that my supervisor and one of his colleagues had been wanting to do some robotics work so it seemed like the perfect match.

I wish I'd had the wits to see how wrong I was but sadly I didn't. My supervisors are both nice people but they have no clue what they are talking about I spend most of the time in our meetings explaining things to them and the only advice they can offer is very vague and not at all helpful. I also found out a year in that my primary supervisor really wanted to do something related to my undergraduate thesis and didn't really want to do the robotics project that was just the hook to get me to apply, he hoped I'd give up and go back to my previous work (which was interesting but not something I'd chose as PhD topic).

To make matters worse I've had no lab space to work in so have been trying to run experiments in lecture rooms (between classes and out of hours). And considering I'm working with small flying robots is pretty ridiculous. Many an hour has been wasted on repairs from collisions with furniture/projectors etc.

I started with the goal of learning more about a field I really love and getting a PhD, and I'm quite happy with my progress on the first goal I've learnt a great deal and am really proud of the skills I've been able to develop. I just don't know if I can finish my PhD.
