Zumo Robot assembled

This week we were busy with building and documenting the first robots based on the Zumo Robot Chassis PCB.

Chassis Base PCB

The chassis is designed to hook up the FRDM-KL25Z board from Freescale. It is using parts from Pololu (chassis, motors, DC-DC converter, line sensor, H-Bridge, encoders):

Power

The robot is powered from 4 AA batteries in the battery compartment below the base PCB. Battery weight is not a concern as Mini Sumo Robots can be up to 500g, and the robot with 4 NiMH AA batteries only has 330g.

One push button is to turn power on, and another to turn it off:

Details about how it works are in the Robot Schematic Presentation PDF.

Optical Sensor

Behind the front blade, there is a IR reflectance sensor array with 6 IR sensors:

It uses the Pololu Zumo reflectance sensor array, but with extended (longer) header pins, as the base board is more off the ground:

The next picture shows sensors attached with a HC-06 Bluetooth and nRF24L01+ module:

The FRDM-KL25Z board gets mounted on top of base board, and sensors connected on the sides:

So far, all components are working. Only the adapter PCB for the IEEE802.15.4/SMAC module is not ready yet.

Happy Roboting 🙂

  7. Good day, please send me the code used in programming the robot zumo this page, I’m going crazy and I can not make it work.
    Already Thankful
