Goose is a mobile autonomous robot I designed and built over 6 months in my spare time for a robotics competition. This was a fully custom and challenging build that tested my competence in electrical engineering, mechanical engineering, control systems, and computer science.
Instead of focusing heavily on the competition, the goal of this article is to briefly go through the system design process. I’ll touch on my various design choices and discuss how I chose to address some of the common issues in designing an autonomous robot. This is not a tutorial (those will be coming later) but more of a case study.
Reading Time: 4minutesPicking up from Part 2, the third and final part of the wood click gears with motor drive build covers the stepper motor drive. The gears ended up driving this really beautiful clock. Note that I did not build the clock, just the gears driving the hands.
Reading Time: 2minutesPicking up from Part 1 of the wood clock gears project where I designed the gears, Part 2 will cover the physical assembly of the gear build. This was the simplest part of the build since it only involved cutting the gears using a laser cutter and gluing everything together.
I was asked to design and build the gear and drive mechanism for a 6 foot clock. The clock had an hour and a minute hand and needed to move in both the clockwise and anti-clockwise direction. This was not a “realtime clock” and needed to move visibly fast.
I decided to use wood clock gears with a motor drive for the sake of simplicity. This build was definitely more out of my comfort zone than usual but proved to be a fun and educational experience. Part 1 goes over the design of the gears. Part 2 will cover the physical build and Part 3 the electrical design and final build.
Reading Time: 3minutesThis was a fun build around the Sure 2×100 Watt Amplifier Module. I spent most of the time on this project designing the chassis in SolidWorks and chasing around the cause of a fairly high noise floor. The final chassis which was very beautifully built by my friend Rodney.
