I don't know of any allied tracked or wheeled remote control bombs from the WWII period. But I am aware of a boat project that was developed by the OSS that fits the description.
It was called project Campbell and was built around an explosive filled boat camouflaged to look like a local native fishing boat. Of course, the style of the boat would change depending on what boats in the region looked like. It was to be controlled by radio signals from an aircraft flying overhead.
The bow had a "pinning charge" that would attach the nose of the boat to the target ship. Then a scuttling charge would blow a hole in the boat's hull allowing it to sink and swing down against the hull of the ship and detonate the main charge well below the water line. This would help assure greater damage and make the target more likely to sink.
I have a copy of the OSS proposal around here somewhere and I don't recall the idea ever got past the testing phase. They actually did build some but don't think they were ever used in combat. So maybe not tracked, but it was a remote controlled demolition vehicle.
