Hey, im new to robotics, but have been interested for atleast 5 years. anywayz i was just wondering what everyone thought would be a good starter kit for me, i want something i can expierment with but can also expand later on. i would like to start off doing simple obstacle ovoidance, and would later like to expand into some sound or voice, mapping, communications and maybe some 3d terrain analysis. All ideas are welcome, if it would be cheaper to just get parts instead of a kit, maybe a list of parts would be helpful. I would like to eventually design a robot that will travel around a house or appartment and remember where key points are and share those with other robots. I plan on taking it a step at a time so i can get confortable with every aspect before moving on to the next step.
