Parts List for Basic 4-wheel drive robot

Hey all, I'm brand new to Arduino and my first project I want to build is a super simple 4-wheel drive robot. I have 4 years of experience with VEX VRC robots and want to build a simplified version of that from custom parts. I'm probably building this with a friend and I want to make sure that my parts are compatible and logical prior to buying.

I have a budget list, and a more expensive list created the main difference is the expensive one includes a Giga instead of Uno to support a display (and a better motor driver).

Parts list below, let me know if I'm missing anything (do I need soldering stuff?) and if the expensive one is worth the more money.

Cheap List ($168.06 USD):

Expensive List ($285.37 USD):

Links to parts (I can only have 4 links as a new user I'll try to include the rest in a reply):

A49AA Motor Driver
TMC2208 Motor Driver
(Yes I know the motor drivers are 5 for 4 motors, both 5-packs were good deals and I couldn't find a good 4 pack)
CNC Shield
Rechargeable Battery

How did you do with the IDE Built-In Examples?

You left out the chassis and the wheels. Probably more left out.

This is a "a super simple 4-wheel drive robot" kit and works well. Even comes with wheel encoders!

There are several similar kits on the market.

I was planning to either use excess VEX parts and then move up to 3d printing. If vex parts don’t work I can probably just find really cheap parts online.

Does everything else work? And would any of this need soldering?

I’m looking to do something almost entirely DIY with buying kinda stock commercial parts.

I’m confident with coding. I’ve done vex vrc coding in c++ for 4 years and a bunch of python and Java before. I’m looking to get hardware experience the coding stuff doesn’t seem too difficult to learn.

Depends on the hook-up wire you are using. Could be solder or could be crimp connectors. Your choice. Might want some appropriate sized heat shrink tubing.

Since you have such a good plan for parts and interconnections, it suggests you have a build plan and schematic in mind.

We can help a lot more if you share those.

You might look at a kit. Student/entry level, something like:

Hobby grade/expandable (also 10x the price), something like:

Got it. My friend has a soldering iron so we should be good if some basic soldering is needed. Thanks!

I really don't though. I'm thinking something super simple like square or rectangle chassis where the Arduino and the battery will sit and then 4 motors connected to omni wheels for 4-wheel drive.

Something even more simple than this, which is a VEX VRC robot. Arduino goes in place of brain, 4 motors instead of 2, and no radio since the brain has wifi and bluetooth.

One of my biggest concerns with compatibility is my battery. It has both a 24v/3a and 12v/2a barrel jack output and I was planning to use the 24v/3a for the cnc shield (to power motors) and the 12v/2a for the Arduino itself. I know the Arduino has a barrel jack itself but do you know what adapter I need to convert a barrel jack into whatever the cnc shield needs?

I'm looking for something more DIY where I build from stock commercial parts as much as possible. I've done a bunch of VEX VRC builds and that's basically assembling from kits, so I want something more DIY.

Zumo FTW!

An ESP32 and a 3D printer (and hours of drawing breathing plastic fumes) will make it "yours."

No idea if it's good. It's inexpensive kit which is better than the nothing I have cobbled commercially so I reckon that's enough.

Their Wild Thumper and TRex sucked but I'm sure they've come a long way by now.

Way I see it, post you deets. Is your motor driver for Lego robots or something that can pull a 200lb load in wagon? Or more?

Student - hobbyist - professional?

You know me. I'm hobbyist class all the way. Never claimed to be a professional.
