Thanks for the advice. I will try to make the router as high as I can. To be honest, I think it was probably a low-coverage area so it should be better nearer to the city (but I'm scared to have dogs chasing it and people wondering what I'm doing! )

Yes, to be honest the mobile phone interface worked out to be best for it. It just needs to be an outdoor robot so that it has space to roam as it's quite fast!

I was thinking, there might be a good and cheap way of building a very capable robot easily based on a cheap 1:18 or 1:16 scale rc car... Mine is 1:10 scale, but most of the cheaper smaller rc cars come with an integrated receiver/esc. If we could find a cheap and working esc/motor pair, or even just a motor controller for the raspberry pi that would work with the motor and bypass the esc altogether, then maybe this would be a very cheap platform for a robust outdoor robot using vigibot!

So, I took the robot out into the world for its first test today! It performed really well, the Vigibot website is incredibly reliable and easy to use. I love how it makes sure that the steering is centred and the motor is off if signal is lost. Very safe!

 

The only real issue that I had is that the signal became very choppy in places. The robot is using a 4G LTE router mounted inside above the 5v battery pack. My phone, or laptop, is using my phone's hotspot. In some areas, the signal was constantly cutting out making the robot constantly stop. I suppose this is probably just due to poor coverage in that area (it was a little bit outside of the city), but is there anything I can do to improve this? Would lowering the camera resolution make it any more reliable? Or any other ideas?

 

Hope you're all doing well and having as much fun with Vigibot as I am!

Hello So, after some testing I have found that REINIT X and Y work only if I control the screen with mouse or touch. When using the analogue joystick on the Xbox One controller, it does not return to centre even when released

 

So, I'm left with controlling both steering and throttle through the left joystick only, as per your first instructions. There is a little bit of a problem with this which is that you are not able to access full steering and full throttle at the same time. I.e you cannot turn left at full lock and also go forwards at full speed. This is because with a single joystick pointing up and left, it does not actuate full throttle and full left steering, rather it reduces both by a little.

 

In the testing I've done, it seems that the triggers are being seen as on/off buttons rather than axes. (It looks like one is for "boost the engines" and I'm not sure about the other.

 

Any ideas on how I can achieve steering control with one axis (either left stick or trigger combination) and throttle with another?

 

Thanks again!

It's coming along very nicely! Thank you so much for your help. This software is amazing. I will recommend it to everyone who will listen I think next I will add a pan/tilt mount for the camera and maybe get a better quality camera. Yes, getting the triggers to work on the Xbox controller would be really good. Otherwise, it would be good to at least have throttle and steering on separate joysticks

That's amazing. Thank you so much again! Forgive me for having such basic knowledge.... My steering is reversed i.e left button makes the servo turn the wheels to the right. How can I fix this? Also, how can I map the xbox controller so that the right trigger is forwards, left trigger is brake and steering is just the x axis of the left joystick?

 

Thank you!
