Raspberry Pi Telepresence Rover

This tank rover by Michael Shimniok streams video to and can be controlled from a web browser. All rover functions are controlled directly by the Raspberry Pi with no additional microcontrollers. It uses our Pololu 30T Track Set, idler wheels, 150:1 Micro Metal Gearmotor MP, DRV8835 Dual Motor Driver Carrier, and Pololu Step-Down Voltage Regulator D15V35F5S3.

LPS331AP pressure sensor test flight

We expect to release a simple carrier for ST’s new LPS331AP pressure sensor this week. While testing and writing example programs for the sensor, one of our engineers, Kevin, came up with a nice demonstration that calculates and displays the altitude on our Orangutan SVP robot controller. It was a beautiful spring day with great flying weather, so Paul and I took Kevin’s digital altimeter on a flight to Lake Havasu City, Arizona, to see how it compared to the altimeter in a plane.

More fun machines, part 2

I posted toward the end of last year about some new equipment we were adding to our manufacturing operations and said the best stuff was still coming. I and several others at Pololu have since had some more personal deliveries of the crying-all-night sort, which delayed my promised update. I still do not have the performance information I had hoped to have by now, but let’s at least look at what we got: Continued…

Freedom Zumo Robot

This robot uses our Zumo robot kit, 75:1 micro metal gearmotors, and a Zumo reflectance sensor array. Instead of an Arduino it uses a Freescale FRDM-KL25Z as the microcontroller board. Sample code is available for line following and maze solving.

Replacement motor for the NERF Stryfe

We recently heard that the Solarbotics RM2 is being used as a replacement motor for upgrading flywheel NERF guns. In this discussion on the NerfHaven Forums, forum member 0reo says:

IMHO, these are the best motors for any flywheel nerf gun that runs on 4 AAs.
