Hi, thank you in advance for any advice!
I'm currently using this product for a puzzle in my escape room, but it's cheap far east unreliable rubbish and it keeps cutting out which is disastrous for the game, I've decided to make an alternative and hope that it can be more reliable.
I'm thinking of using something like this tank chassis with a dual motor controller and a joystick to control it, along with a webcam on top that streams to a monitor.
I'm looking all over the internet and I'm struggling to find something specific to my needs, I have found "stream webcam to smart tv", but it's wired. I've found "stream phone camera to smart tv" but it needs to be an easily chargeable and reliable solution that isn't going to die on me, I'm outta ideas!
I got a wireless webcam and tried to set it up to a pc monitor and link them over a wifi router, but the thing kept mysteriously dying on me (as in, sometimes refuses to connect), it causes me mountains of stress when I have paying customers in and the equipment is unreliable.
It's especially stressful at the moment because problems that are sorted by entering the room and getting close to customers are not COVID safe! I have to just issue refunds, I can't go on!
That's why I wanted to ask, is there a way to connect the webcam directly to a smart tv? (fewer moving parts, fewer things that can go wrong)
I have seen arduino controlled cameras that can connect to a pc, why not a tv? Sorry I'm not massively tech savy 
How about a wireless bird box camera! Daytime colour + night time B&W. It needs 8V @ 150mA to power the camera - yep, that's 8V - no idea why! It comes with a receiver to connect to a TV. You can find more info here if you're in the UK. I'm sure that there are other variants out there.
Who is watching the monitor? The player or the Game Master, or both?
The GoPro Hero and, I'm sure, other "Action" cameras transmit images over a 2.4 GHz link.
Any model aviation hobby store will have 2.4 GHz cameras and receivers.
In my own drone, I use the GoPro4 and a separate 5.8 GHz transmitter supplying live video to a 5.8 GHz receiver.

What an excellent idea! I love it!
Slight issue, I only found this battery as an 8v power supply (why would they make it 8V?! haha)
The thing looks quite weighty, I worry a small tank might not be able to haul it, maybe though, it might not be a problem. There's actually an official one on that website you linked that looks a bit lighter
How important is hitting that 8v? Could I not just use a 9v? Or 7 AA batteries in series? (8.4) then do I need to faff with a power supply to control the current? Sorry supplying the correct power to my projects has always confused me

Another good suggestion, thank you so much! I actually have a go pro hero 3, the customer has to be able to see the feed but it would also be awesome to have it go through to a second screen that I could view. Is that easy to achieve?
I just read through my instruction book, such as it is, and it says: "Insert the DC+8V/500mA (or DC+12V/500mA) power adapter into the interflow power plug and insert its DC output plug into the DC input plug of the camera transmitter to put through the circuit."
From that jibberish, it suggests that you can use up to 12V to power the camera!
My kit came with a PP3 9V battery adapter that plugged straight into the power connector of the camera.
BTW the camera weighs 60g.
