After a second revision, I have completed the power board for the Mecanumbot. This board has the following features: automatically selects between two batteries and the wall chooses the wall if available, otherwise drains the batteries one at a time provides power voltage and current measuring via ATmega168 running the Arduino bootloader communicates to the primary vehicle Arduino over I2C provides regulated 5V power for the robot LEDs Downloads Eagle…

To make the connection between the laser and the computer cleaner, I decided to make a PCB. (My first PCB! Woohoo!) I followed the schematic from the Neato Laser guide on the ROS wiki. I later found out that there was one error in the schematic – the…
