Recently, we made a DIY ball launcher and got a lot of responses.

Then Makeblock share a ball-picking machine to answer our project.

They made it in their Makerathon.And it just cost 48hours.But still

insteresting enough to share with you!

So I share their article here now.(Original)

Step 1:

5. Washer 4*7*2mm *2

6. Bracket U1 *1

7. 8mm shaft wheel connection piece *2

8. Bearing 8*16*5mm *2

(1) Install 8mm bearing bracket A in corresponding positions of beam 0824-160 (2X).

(2) Install bearing 8*16*5mm into 8mm bearing bracket A (2X).

(3) Install 8mm shaft clamping apparatus with 8mm shaft wheel connection piece (2X).

(4) Fix 8mm optical axis on rotary disc of steering gear through one of 8mm shaft clamping apparatus.

(5) Install assembled steering gear and optical axis on 8mm bearing bracket and 8mm bearing.

(6) Install steering gear with bracket U1.

(7) Install the other 8mm shaft clamping device in the other side of 8mm shaft without clamping.
