5lbs Wedge Sumo Bot

5lbs Wedge Sumo Bot :

What is this: 

This is my 5lbs 3d printable sumo bot with 30 degree inclined wedge in the front made in fusion 360. It runs on an Arduino uno + l293d motor shield, 2 tt motor and a 2s lion pack. Basically a small pusher that gets under the other bot and shoves it out of the ring.

Why i made it :

I just wanted a simple sumo bot to learn by doing. I'm still tweaking it and learning from every test run. 

To develop my cad skills :)

How i made it : 

I started by designing the chassis in fusion, a low wedge with two ramps like structure in 30 degree in front. First, i added one platform limit after that i put all the model of TT motor, wheel, Arduino uno, l293d shield then i started to make sketch in the motor to make it like a box structure after making half box structure i just add one wedge with 30 degree inclined; then i just mirror it. Finally, i draw sketch at the top to make the top plate and it's finished :)

Assembly Guide :

Parts needed:

• 3d printed chassis and top plate 

• Arduino uno (1)

• L293D motor driver shield (1)

• TT gear motor (2)

• 2S li-ion battery holder (1) 

• 18650 li-ion cell (2)

• switch (1)

• jumper wire 

• USB cable (for uploading code)

• screw for the top plate 

Steps need to be follow : 

• Print the parts both chassis and top plate then clean up and check the standoff holes aren't clogged.

• Mount the TT motor on both sides with screw and put the wheel on.

• Put the Arduino uno on the standoffs and it should perfectly line up with the port hole.

• Stack the l293D shield on  the Arduino uno. 

• Solder all the wire with motor, switch, battery and join it in shield.

• Upload the code with the USB cable through the side hole. (Coding Part is yours)

• Test run check forward, reverse, and turning.
