I think the blender equivalent to drawing a spline and sweeping it (at least, as far as making hoses is concerned) is drawing a bezier curve, and adding a bevel object [Bev Ob] (I usually use a bezier circle.) Scale the bevel object to change the size of the tube.
This is a quicky hose, a bezier curve extruded twice, so it has four control points, and a small bezier circle (the disk surrounding the 3d cursor.) The controls are in the editing buttons, Curves and Surfaces panel. Be sure to select the 3D button if you want to move the hose off the plane it starts out on. It doesn’t matter where the bevel object is, so you can hide it inside the camera bot, or put it on another non-rendered layer. It does matter, however, where the bevel object verts are in relation to its object center, so when you move it to hide it, move it in object mode, not in edit mode (Try it in edit mode to see what happens – you can get some interesting effects.)
The camera bot is very cute. I like it. Very good work on texturing, btw.
Are you planning on animating the little bugger?
