Information

LaunchBot

LaunchBot is a $15.00 programmable robot with a 16bit processors from TI.  

The robot is programmed in C, using a professional development environment called Code Composer Studio.

This firmware is for the MSP430Launchpad and is based off the TI Launchpad example for Code Composer Studio 4.

The firmware turns LaunchBot into a line follower.

See video on this site.EMGRobotics_LaunchBot.zip

 

 

 

LaunchBot is built using this $10.00 kit from kitsusa as a base:

and this $4.30 kit from TI with a 16bit MSP430 as it's intelligence:

The total cost of the robot is less then $15.00

 

The robot includes two line sensors ( IR sensors pointing down ) and two motors providing differential drive.  This robot is perfect for line following and maze competitions.

 

The robot is programmed in C using the professional development tool, Code Composer Studio, from TI.  The TI MSP430 in the Launchpad kit is a professional RISC microcontroller used in automotive, industrial, and medical products around the world.  Time spent working with the TI Launchpad and the MSP430 can be counted on your resume.  Design experience with the TI MSP430 and a understanding of the Code Composer Studio development environment are skills desired by many employers.

thanks for your help guys, now i have the main base  for start working with  the bot,i agree with tim, it's an interesting robot to start learning.

the maze doesn't have walls, it's made by electrical tape lines. and the bot has the original configuration

Eric,

will you please detail the usage of a resistor and capacitor in dead-bugging the MSP430 controller? I'll probably be using a 430G2553 if that makes a difference. So far, I just don't know why you need the res + cap. Thanks.

The resistor connects between DVCC and RST.  It should be about 1K.  The capacitor connects between DVCC and DVSS.  It should be about 16uf.

Thank you. Now I just have to understand why these values work so I can make the right choices on my own later when dealing with other chips.

I really appreciate all the info you've provided here and across the entire website.You have inspired me to contribute to the robot uprising in new ways.

Actually the cap is 16v, 47uf.

The values are not chip specific as much as application specific.  For the cap, I chose the largest I could find based on price.  16v, 47uf is a very popular size and is therefore very low cost.  47uf is more than enough for the motors I use in my robots.  The 1K was also chosen based on noise.  Anything bigger than a few K was not pulling reset up hard enough and causing resets.  1K does a good job of pulling up reset even in some of the noisiest environments.
