To Be More Effective

1) Keep a list of what needs to be done
2) Create a habitual time to get things done, keep your energy in mind
3) Set yourself up for Small Wins
4) Focus on what will not change
5) If you need people’s help, there are two arguments you must make, analytical and emotional
6) People will not change unless the change makes their job easier, you remove all other options, or sometimes if it makes something possible as long as the reward is proximate to the effort
7) Give them charge and then give them room
8) 80/20

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.
