Overview:

After research process and gathering necessary design, mechanical and coding data`s, i started the to design the robot. Whole design created by using Shapr3d on iPad. It can throw the ball to the every spot on the table by moving up/down and left/right. I used the Arduino for the movements but since the code is used for another project, I am not able to share it. Since I didn't include the coding, I also didn't include the required electronic hardwares and assembling. This is only the mechanical part of the project. But, please feel free to reach me for your questions!

Building:

I will break the design into three main parts:

1) Front tube

2) Middle tube

3) Rear tube

To complete this project you will require basic hand tools;

Alien Key for M3 Screws
Wrench for M3 nuts
Sandpaper for a better surface quality 3d parts

Assembling processes are explained in the further steps with visuals.

Supplies

All parts are manufactured by FDM 3d printer (Flashforge Guider IIs), other required parts are listed below;

Number------Name:

2pcs-----------Nema17 Step Motor

2pcs-----------DC 6V Gear Motor with Long M3*55MM

1pc------------RS-385 Metal Gear DC Motor

1pc------------Ball-bearing (26mm outer dia, 10 mm inner dia, 8mm thickness)

2pcs-----------Wheels with the rubber (70 mm outer diameter, 2,3 mm inner diameter, 11 mm thickness)

15pcs---------M3 nut

5pcs-----------M3 Screw (12 mm long)

6pcs-----------M3 Screw (16 mm long)

10pcs---------M3 Screw (20 mm long)

Front Tube

First part is includes;

1pcs - Front tube (3dprint)
2pcs - DC motor holder (3dprint)
2pcs - RS-385 Metal Gear DC Motor
2pcs - Wheel
4pcs - 3M nuts (16 mm long)
4pcs - 3M screw

-After Assembling the both sides, Dc motor holder can be adjust according to wheels measurement. Thanks to adjustability of wheels height, different size of the wheels can be used in the project.
