I wanted to do the same with but with a large agricultural tractor.
I think we are nearing the point where a camera can monitor my body movements and mimic it fairly accurately in a robot. Combine that with gloves for hand tracking, VR goggles, audio headsets and maybe haptic feedback and we can effectively have remote experiences.
Once that’s the case, you put a robot in a tractor seat; add a bunch of cameras (for VR), microphones (for audio), and a couple robot arms with humanoid hands attached (https://www.psyonic.io/ability-hand https://www.psyonic.io/ability-hand).
I can then remotely control the tractor in VR space, but have it operate 100 miles away
- wongarsu 4y agoI understand why you would do it, but using robot arms to control another robot seems like a lot of accidental complexity. Surely there has to be a generation of tractor that's new enough that most functions are exposed on CANbus but old enough that it isn't locked down yet?
- Nextgrid 4y agoThe lockdowns are only for the user-facing diagnostic port. I'm not aware of any vehicle that uses encryption & authentication on the inner buses. Your only challenge is to reverse-engineer the meaning of the messages.
- bri3d 4y agoSome modern vehicles with FlexRay have full-bus encryption, and very modern CAN systems usually use HMAC for security sensitive stuff like immobilizer and key commands. I think ADAS systems will probably use similar in the coming years as vendors become more concerned and upset with system tampering. But, yeah, overall, most vehicle control systems are far less evil than people seem to think. I think part of the issue is that the "vehicle hacking" community have managed to massively over-hype basic protocol / message reverse engineering.
- MichaelCollins 4y agoWhat if you ripped out all the control electronics, leaving only the actuators, and replaced the control circuits with off the shelf parts? I expect it might cost a pretty penny, but it should be doable right?
- Nextgrid 4y agoAt least for engine management that's definitely doable, there are off-the-shelf ECUs for race/custom cars that are meant to be used like this (configurable via USB so you can tune every parameter). For everything else you will most likely need to go custom but it's absolutely possible.
- lettergram 4y agomy actual thought was if I could get it to work - big if - I could then move it to literally any tractor. Effectively, I’d have a massive market.
- HeyLaughingBoy 4y agoI think the biggest problem you'd run into is that people are cheaper than your automation. A 16 year old will run your tractor all day for minimum wage.
- lettergram 4y agoYeah and be able to attach items, no doubt. But I kind of just want it for the fun nature of it.
- avgDev 4y agoI can't wait to drive your tractor in a sim.
