Low-Cost, beginner battle bots! We will be constructing the chassis from cardboard, and using low-cost electronics. The cost for the basic kit is 25.00.

We are just starting the club, so we are creating house rules by tweaking existing rules from other clubs. We are basing the rules off of these (http://www.columbiagadgetworks.org/wiki/index.php/Combat_Robots), though we will go up to 10×10 and heavier weight.

We will also need to build a battle box, so participants will be expected to chip in at least $10 each for that.

Here is a list of parts we are using for the base kit:
Platform specifications:
NodeMCU (ESP-12E module with ESP8266 controller) and motor shield / breakout board. Available here: https://www.aliexpress.com/item/NodeMCU-Development-Kit-NodeMCU-Motor-Shield-esp-wifi-esp8266-esp-12e-esp-12e-kit-diy-rc/32445659965.html.

Two ubiquitous, cheap Chinese motor modules (UCCMMs). Available here: https://www.aliexpress.com/item/HK-POST-FREE-Wholesale-48-1-Plastic-DC-Drive-Gear-Motor-Tyre-Tire-Wheel-For/32603795906.html.

Or an improved quality, domestically sourced alternative with motors and wheels purchased separately:

6 AA battery holder, such as this one: https://www.aliexpress.com/item/10-PCS-6AA-Battery-Case/32675020506.html Rechargeable NiMH batteries are highly recommended, as battery life is 1-2 hours on Alkaline cells.

Arduino core libraries for the ESP8266.

Control over WiFi from a mobile device or computer via a browser-based user interface.

Cardboard robot body, ranging from a simple box, to a laser cut design from CAD.

We will meet once a month to work on our bots then end with a battle (we can’t use serious weapons until we get the battlebox built). Our first meetings will involve getting our rules set. We can order parts for you (prepaid only, and they take awhile to get here), or you can order your own. Come join the fun!
