Jamee's dead reckoning robot

Several Pololu employees made robots for the LVBots dead reckoning competition. Unfortunately, my robot didn’t work enough in time for the competition, but perhaps the description of my robot might give you ideas for your own dead reckoning robot. Continued…

Zumo Robot with Pololu Plug-in Modules

Posted by Jamee on 8 October 2013

Forum user Erich created a custom Zumo Robot Chassis PCB to use with our Zumo chassis kit. The board is designed to accept a large number of plug-in modules, such as a DRV8835 dual motor driver carrier, encoders, and voltage regulators. Sensors that can be mounted on the robot include a Zumo reflectance sensor array, some distance sensors, and an ultrasonic sensor, and it also supports several wireless communication modules. Instead of an Arduino, it uses a Freescale FRDM-KL25Z as the microcontroller board.

Mini Maestro 24 controls a parallel LCD

Posted by Jamee on 23 September 2013

In this video, forum user Dev255 controls a standard (HD44780 parallel interface) 4×20 LCD display with a Mini Maestro 24-Channel USB Servo Controller and displays the value of the potentiometer (converted to a percentage) on the screen. You can find out more about his project and see his Maestro script in his forum post.

Wirelessly-controlled robot with PIC and nRF24L01+

Posted by Jamee on 10 September 2013

In this video, Amjad Al-Ahdal demonstrates his wirelessly-controlled robot with multiple modes that he programmed in C. The robot contains a PIC18F2455 microcontroller, an nRF24L01+ transceiver, a SN754410 motor driver IC, a Pololu wheel and encoder set, and two 100:1 Micro Metal Gearmotors. Its controller has a homemade keypad, another transceiver, a 9DOF sensor, and a serial 16×2 LCD screen.
