IR v. Sonar

I've been making plan for an obstacle-avoiding robot, and was originally planning to use a Sharp IR range finder for it (10 - 80cm), but after seeing other sonar range finders, and other people's projects (the majority of the ones I see seem to use sonar), I was wondering:

Which is better: IR or sonar?

'Cos IR recievers can be affected by ambient IR light, and the best i;ve seen goes up to 150cm, whereas I;ve seen sonar ones up to 7.4m, roundabout, and they can't be affected by ambient sound (I think).

Scaling down a boat to make USV

I have been dealing with asects of theis for a while and this is my latest idea. Build a small plywood boat downsized to be a platform for robotics testing. I bought a "partially built kit" on eBay that turned out to be an abandoned upgrade of a hobby grade boat. It's a 15" V narrow plastic V-Hull and I am concerned about it being to close to max with a decent battery and gear in it. But the upgrade in process inculded a good servo steered rudder and through hull prop hardware. The supplied motor is marginal but workable. I have a brushed ESC with 5v BEC.

start here robot ultrasonic sensor

Newbie here

Hi every one i have been member for a while now and have finally collected all the parts needed to complete fritz start here robot.

Every thing is the same apart from im using a 28x2 picaxe instead of the 28x1 picaxe,also using the ultrasonic sensor pictured below (in attachments instead of the SRF05.

i have followed the walk  through on http://letsmakerobots.com/node/66  for the SRF05 sensor and translated the wires to my sensor as followed:
