DCMotorsMobile Robot : Full 3D Printed Chassis

dubbie

I printed out the remaining part for my half dome head for the DC  Motor Mobile Robot and I decided that I did not really like it. It didn't fit together particularly well and it just didn't look very good. So, I decided to return to my original idea of a complete dome head. This was quite simple to do although it took 2 1/2 hours to print the dome. The new base plate took another hour. However, these two parts now fit nicely together with a good interference fit and I think it looks much better.

 

In stead of a flat plat on the outside of the dome I put a small plate on the inside to make it easier to fix sensors PCBs to. I also added two small holes which are a bit like eyes and I might put LEDs in these or perhaps some suitable sensor. As the dome is now complete I will have to find a way to connect the cable for the servo motor, maybe drill a hole in the back of the dome. At present I'm not sure where the Arduino controller is going to go.

 

 

Now I can start to work on the electronics and the creation of an autonomous mobile robot with four wheel drive.

    Shabaz,

     

    Thanks for your comments. It has been great fun designing and making all the parts, especially when they fit together nicely.

  • Wow, very nice-looking robot! It's a great idea to use the movable portion for sensing/monitoring or illuminated eyes. It's great seeing this robot take shape : )

    Donald,

     

    I quite agree about the 3D printers. It is much easier to create more complex shapes such as domes with one. I would have great difficulty making a dome any other way. Plus it also makes it much easier to make changes and updates. The only drawbacks are that sometimes, for reasons I am unable to determine, some prints are OK and others are not! The parts are not very strong either although they are perfectly OK foro the small mobile robots that I make. I think my favourite part so far has been the wheels for the DC Motor Mobile Robot, I really like them. I have been thinking about making the wheels for my robots for years but managed with purchased ones, these are the best I have done, especially now I am getting the hang of matching the hole to the axle size in order to achieve a good fix. I quite like the dome as well. Somehow, curves seem inherently more attractive, I'm not sure why.

  • Dubbie,

     

    I too like the look of the full dome.  Very nice!

     

    Keep up the good work!

  • Having a 3D printer certainly opens up other avenues for your robotics builds and much easier to reprint, than cutting things outbid hand and having to start again.

     

    Look forward to seeing how you get on with the electronics.

     

    Kind regards.
