KTR-X1 8x8 This is a vehicle remotely controlled to perform tasks in very difficult terrain, characterized by simplicity of construction, low center of gravity and universality.

KTR-X1 8x8 is made of two sections connected by joint, so that each section is independent, wishbones further moving offer enormous possibilities in overcoming the obstacles on the ground. The vehicle in whichever area is moving, and as is always excellent grip on all 8 wheels.

Thanks to that KTR-X1 is a hybrid can confidently go on long trips because we do not run out of power.

Some project

Quite a project and the first hybrid that I have seen here. It’s a good idea, and obviously is well put together.

I’d like to see the rotary snowblower in action. And I have no idea what "Incineration"means, unless it is fuel consumption.

How does the steering work?

So powerful

It looks great! Would if hold you on top also? (Thinking in medical porpuses for it)

It would be awesome a chassis like that but smaller for medium sized robots

Congratulations!

Tremendously Impressive Project.

Tremendously Impressive Project. When I was getting started, I had a Zero-Turn Lawnmower I was tempted to turn into a robot, eventually I decided to focus on smaller bots that wouldn’t crush people.

I had the same questions as CyberJeff on incineration and steering.

It reminds me of the Oshkosh 8x8’s the military uses to transport fuel and supplies.

If I had one of those, I would want to mount a paintball gun turret and a bunch of sensors on top.

Good luck. Really great work.

This is awesome!You must

This is awesome!

You must have had fun building this. Great work.

Regards,

1000 Words +

They say a picture is worth a thousand words. I would say that picture is worth a lot more.

Thanks for posting You are quite an engineer.

Segmentation

Cars and tractors are not segmented, but in mother nature, much is. For a creature crawling on the ground this enables them to follow the terrain closely.

Others have commented on the engineering, and I think that is very good. What is much rarer is to solve a problem (how to traverse difficult terrain) and find a simple elegant solution. Well done.
