plan to change the bigfoot-Bot

After a few days of analysis, I decide to make a few changes on the Bigfoot-Bot (I named it). Due to all wheels are connected to motor by rigid shafts, the kinematics for the robot to turn around will be different from Boe-bot. The way it can turn around is by wasting large amount energy on sliding wheels, where control of the robot in many aspects will be difficult. Hence I decide to modify the robot base and change the electronics, so that it can be better fit into my project.

Lots of works needed to make the changes…

I layout the following graphs to make everything in plan and allow myself to have more directed view on it. (Some friends asked me what is the software that I usually do the layouts, it is Microsoft Visio.)

List of the changes

• One set of gear train and one encoder will be added. (parallel with the other side)
• One set of Parallax education board, Basic Stamp 2 and embedded Bluetooth will be added.
• Two front wheels and dc motors will be replaced by one swivel wheel.
