zlalanne 37 Posted June 18, 2014 Share Posted June 18, 2014 Using my RedBot BoosterPack I have created a small remote control robot. The motors + chassis costs $15 from SparkFun so it's a pretty low cost solution to get started in robotics. On the controller side I use the CC1101L for wireless communication and the Educational BoosterPack MKII for the joystick. The F5529 LaunchPad simply reads the joystick value and decides which way the robot should move and transmits the data using the CC1101L. Here is a picture of the controller, note the CC1101L is on the bottom of the LaunchPad to make the joystick easy to use. On the robot side the F5529 LaunchPad is connected to the CC1101L BoosterPack to receive the data from the joystick. It then uses the RedBot BoosterPack to control the robot. The GitHub repository is located here, which includes hardware + software. The remote control code isn't uploaded yet but will be once I clean it up. And now a video of it in action (phone quality).

adrianF 43 Posted June 20, 2014 Share Posted June 20, 2014 This is super cool! I'm continually impressed by the simpicity of the CC110L SubGHz RF BoosterPack. The Energia library makes bi-directional RF communication absolutely trivial! Your BoosterPack is a great way of leveraging both the SparkFun RedBot ecosystem of sensors, chassis, etc, while still being able to stack additional BoosterPacks from the TI ecosystem... Do you think you could power the RedBot motors, components, LaunchPad, etc using the BOOSTXL-BATTPACK Lithium Polymer Battery BoosterPack? Quote Link to post Share on other sites
zlalanne 37 Posted June 20, 2014 Author Share Posted June 20, 2014 The way the design is set up the board would not work with that Lithium Polymer Battery BoosterPack. The motor driver IC is connected straight to the battery source to provide the best performance for the motors. You could probably jump the 5V output from the BoosterPack to the barrel connector and disable the LDO with the onboard switch and have it work, but running off the 6V battery included with the magician chassis will still perform better. As for this project, the battery BoosterPack would make perfect sense on the remote side to be used with the CC1101L BoosterPack and the Educational Boosterpack MK II to control the robot.

Rickta59 589 Posted June 21, 2014 Share Posted June 21, 2014 ... The motors + chassis costs $15 from SparkFun so it's a pretty low cost solution to get started in robotics ... Do you have a url link on sparkfun.com to this package? All I could find were versions that were much more expensive. -rick Edit: Figures, after I spent a bunch more time searching. I found it. It is called "Magician Chassis". They also sell another one called "RedBot' which is a lot more expensive. Here is the $15 one: https://www.sparkfun.com/products/10825 Quote Link to post Share on other sites
zlalanne 37 Posted June 21, 2014 Author Share Posted June 21, 2014 Yes I guess the "RedBot" is actually the Magician Chassis, with the RedBoard and some line following sensors and an accelerometer. The "Magician Chassis" is just the chassis with motors which sells for $15. The BoosterPack aims to replace the RedBoard for the LaunchPad ecosystem. Quote Link to post Share on other sites
SixSixSevenSeven 23 Posted June 21, 2014 Share Posted June 21, 2014 for anyone interested, the magician chassis is a DAGU product with sparkfun being one of the main US distributors. Quote Link to post Share on other sites
