Hi @Zhorik ! Thank you for sharing this project. It really looks professional. I’ve watched the whole video 
What is the max speed of this robot? How much did the parts cost to make it?
I current time maximum speed is 2 km/h, due to some issues with motor drivers. On the next Version speed will be 5 km/h without variator and 25 km/h with speed variator. Production cost, only hardware will be approximately 3000 Euro. Software plus machine Vision can increase cost up to 4000-4500 Euro.

Oh wow this robot is awesome and it’s not a small desktop one, its an out door sized robot, right up my street

Thanks for the compliment. It will change in the next version. Its dimensions will decrease, and the carrying capacity and speed will increase.

Yes you are right, already fixed.

The two videos you had added were hidden on the side, so I added them to the description. Hope that’s ok.
Have you been able to start the second milestone? Any progress?

Hi, everything is ok. Thank you for your help. At the first stage I have made new design of robot in the Solidworks. Afterwards I had many simulations of moving up to stairs and down. Plus many others tests. After almost rework everything rest is accumulator box which i have to complete during next two days. And that is it.Well from next month I will start to order and buy all parts, it is not so simple stage to. In parallel I am going to complete during one month concept of neural software, i have this conception but i need adapt it. So, really everything goes as i planned. New variator for robot still not completed in Solidworks because necessary to complete some simulations but idea absolutely correct and guaranty that it will works. Would be nice, of course, to start to make even design of new engine for travelling to the Moon, but unfortunately i am alone and do not have so much time, nevertheless i hope step by step and i will have time.

Did you have plans to have the top pivot so it stays horizontal while the robot goes up stairs at an angle?

Excuse i didn’t understand your question. I have plans to make head for robot like “Johnny 5”. I don’t want repeat it but head will be. I already made it design but did not shown it in the main image. After last Simulation robot can climbing up to stairs 45 grad with payload 100kg. On the flat surface it payload can be about 250 kg. Robot does not have any restrictions how to moves on stairs.

In the videos, the payload (the blue box) is fixed on the top of the robot, so when it’s going up stairs, the box is at an angle. If you added a pivot, a linear actuator and an accelerometer, you could keep that box (and its contents) horizontal.

Now i got it. I thought about it and it is possible to make but i do not want to do it. Reason first: it does not have almost any influence on critical angle of ascent. Second: it is increase cost of robot a lot of. And last: universal guides on the top of the robot allow you to change the position of the box and tow trailers. Besides possible to attach different external tools such as snow removal, street sweeping. You can even use than robot in warehouses in automatically dispensers where it will come ship and return boxes with things. For all this stuf i am using universal guides and if you need to have top pivot so it stays horizontal then you have make box with this capability and attach to Zhorik. Individual functionality will be realised on tools self.
