Sketching Robot Designs and Parts with Dimensions

Inspiration

I’ve always been intrigued by battle robots, and when I discovered that there is a competition near by that hosts mini battle bots, I was immediately drawn to it. I did lots of research into it and discovered there were many categories and classes. I decided to make a bot for the Antweight plastic class category, and one that would easily be upgraded to the open class category. An example battle bot is shown below (not mine).

Overview

The Antweight Battle Bot competition is a miniature combat robotics event where custom-built remote-controlled machines face off in a bulletproof, enclosed arena. This weight class serves as the ultimate entry point for engineering hobbyists due to its low cost, minimal space requirements, and strict design constraints.

Weapon and drive motor sketches with dimensions

I first sketched out the motors and electronic components used for the battle bot at a 1:1 scale with dimensions, to give me a better sense of the sizing of the parts and to start thinking of the arrangements.

Bot concept sketches

After planning a base robot in my mind, I finalised 3 main robot designs I liked. I sketched these 3 out and asked for input from a few people who have experience in this field, including Angus from makers muse (the YouTuber). I decided upon the vertical spinner design with aggressive front forks. My 3 bot sketches are attached below.

Version 1: Viper

Version 2: (Unamed)

Version 3: Skull Krusher
