There have been many remote controlled Technic sets over the years. I've organized this list with the most recent generations of remote control elements first.
Current remote controlled Technic sets will contain a Control+ hub. We can find them by showing the sets that contain that part on Bricklink.
For Power Functions, we can look for sets containing the Power Functions IR Receiver and sets containing the PF IR Receiver V2. It looks like the following sets contain that part and are remote controlled:
- Motorized Bulldozer 8275
- Motorized Excavator 8043
- 4x4 Crawler 9398
- 4x4 Crawler Exclusive Edition 41999
- 6x6 All Terrain Tow Truck 42070
- Volvo L350F Wheel Loader 42030
- RC Tracked Racer 42065
- Remote-Controlled Stunt Racer 42095
Prior to Power Functions, there were dedicated RC elements used to provide remote control functionality to sets. These can be found in this category on Bricklink. Most of those sets aren't really Technic, but some are. For proper Technic sets, it's probably helpful to look at just the RC sets containing a separate buggy motor instead of the large integrated vehicle base. Those three sets are:
- Hot Flame 8376
- RC Race Buggy 8475
- Supersonic RC 8366
