Here is the video demoing the motor controller. I used a Mr.Basic robot platform and included a little review about that platform. Code is found after the break.
This is the robot I quickly built to demo the Low Voltage Motor Driver. If is based off the Mr. Basic platform and MSP-430 Launchpad. It has a 6.4V lithium battery as the main power source which feeds into the voltage regulators on the Launchpad.
For direction control a top mounted servo spins a Sharp gp2y0d810z0f IR sensor. The sensor has a single data line which is pulled low when a object comes within 10cm of the sensor.
Most of the code for the hardware is already written. Just need to finish the controls and it will be ready for a video.
I finished the first physical version of the msPROBOT just in time for Maker Faire. I have the majority of the demo code written and I will post it when I test the code. All the basic library functions are written. Just need to make a main program that strings it all together.
There is more information and PCB files you can download at the msPROBOT project page.
I just received notification that the msPROBOT PCBs shipped from China. They will arrive on Monday. I have the motor controller pretty much coded out. I will post it later today.
I finally finished the first version of the chassis files. This one is just laser cutting. I will be releasing two more sets, a 3D printed one and a template for hand cutting.
The chassis files will be in AutoDesk 123D format. It is a free 3D modeling program aimed at makers.
Close to 50 parts! msPROBOT project page.
