TurtleBot 2

ROBOTIS and OSRF, recently announced a TurtleBot 3 (TB3), that will cost around $500. This got me thinking about the previous version, TurtleBot 2(TB2), which was really an evolutionary approach to a creation, driven by a desire for affordability.

The TB2 utilizes a Kobuki Base, for a standalone cost of approximately $350, plus $55 for a charging station(formerly an iCreate 2 base, with an associated cost of $200 inclusive of base).

There are two distributors in North America, Clearpath Robotics, and Dabit Industries, both offer an “essentials kit” as follows.

My System For Personal Organization

At some point you stop waiting for time, and realize that time is waiting for you. If you aren’t where you want to be in life, when you come to this realization, it can be an empowering, energetic, feeling. Hopefully, you take that energy and use it to build a bridge to that place you want to be.

I used it to develop a 20 year vision: then necessary goals and habits to get there. I had some difficulty developing a clear vision of what I want. I have not reviewed much of Brian Tracey’s material in detail, but the blog of his, I stumbled upon, provided some insight.

With a clear vision in mind, I wrote down my goals and soon to be habits while ensuring they fit my vision. I then set off to develop a system to track and measure my progress.

Having had difficulty in executing past goals, I needed to figure out a means to create milestones, time to work on these milestones, and a trigger to work.

I started by created a time allocation schedule(in Google Sheets), to plot my routine to work on my goals and good habits, which I will review every Sunday.

I used Strides to create a dashboard and monitor and track my habits and goals. Some goals were better suited for Strides than others, habits were a great fit. For instance it was easy to set a habit to Meditate three times a week, and monitor progress. On the other hand, the App had difficulty accommodating my goals to read 12 books, or take two online-courses. I settled by creating a “reading” project in Strides and then created 12 milestones, one for each book I wanted to read in the coming year. Similarly, I created a separate project with two milestones, one for each course I want to take. To track these, I must manually enter and estimate my progress on a 100 point scale.

One large goal in particular, requires a significant number of milestones that will likely change as I progress and learn. Therefore, my “Dare to Dream(DTD)” goal as I call it, is entered in Strides as a time average. In other words, I hope to commit 12 hours per week to start.

I created a Project in Asana to organize my thoughts and create tasks to achieve my DTD goal.

And finally I used Evernote as a real world notebook to record anything that comes to mind that does not fit in one of my other systems.
