Arduino-powered omni robot gets an upgrade
— January 29th, 2019
When we last saw this omni robot by Jeremy S. Cook, it was lurching around under Arduino Nano and Bluetooth command. After much work, he finally has it to a state where it rolls nicely on a flat surface—even carrying a little strandbeest at just after 8:30 in the demo video.
The biggest revision for the robot was new “grippier” wheels, but electronics were also enhanced, including a LiPo battery (with a voltage divider monitoring circuit), potentiometer for speed control, and LED eyes.
Changes were facilitated by a screw terminal board attached to the Nano, which minimized solder work, while keeping the robot’s wiring secure. More details and code are available here, while the upgrade/troubleshooting process can be seen in the video below.
