Hi Ray @electricray1981 ,

 I watched your great video and noticed the reference to the fuse ... but didn't realise I had played any part in its existence!

You now have a great platform to develop some great research projects on ... unlike the movies, I look forward to the sequel of your video, as it promises to be better than the original ... and not just another brick in the wall. 😉 

Best wishes, Dave

@davee I'm Not sure if I understand you message completely. But I hope ou did not try to tell me the video was bas....hahaha. I'm not a full time youtuber actually and also not a native english speaker. 

But like I have done before I love to come back here and post any interesting updates.

Grtz,
Ray

Hi Ray @electricray1981,

  Sorry for any confusion ... your video was excellent.

  The second paragraph was saying that I look forward to seeing a follow up ... as I guess you will be looking to make the control system more 'automated'.

Most successful 'big movies' (e.g. 'Raiders of the Lost Ark') have one or more follow up sequels, many of which tend to be worse than the original, usually because they do not have a good quality plot ... but if you continue to progress your robot, then I think you will have a great story line for your next video!

By the way, in your video, you naturally have an accent that is different to that of native English people, but your command and pronounciation of the English language is excellent.

Best wishes and apologies once again for any misunderstanding,  Dave

Congratulations on your progress so far it looks very professional.

I assume you are actually using ROS in the demo to integrate your code?

One of the things I dislike most about these small robots is their noisy motors which I think mostly comes from the gears.  The 24volt window screen wiper motors I used on my medium sized robot base were very quiet. At the end of the wiper motor shaft is a spiral gear (metal) that rotates a gear wheel (non metal).

Yes the robot is running on ROS Noetic. And than by assigning the correct IP addresses I have Roscore running on the Jetson Nano but I can read all topic and cotrol the robot from my Ubuntu VM runningn on my desktop. This works quite handy but was a hassle to make it working cause the VM creates their own range of IP adresses. Long story but it works.

I agree they are noisy this toether with the high freq of the pwm for driving the motors will make you crazy if this robot would drive around you the whole day like the real R2D2 e.g.

Great point you made about the screen wiper motors, I will consider this for an upcoming project thanks!

 

Grtz,
Ray
