A concise summary of my March 2026 talk to the Dallas Personal Robotics Group on the Maker's Pet ROS 2 robot kit: hardware, software architecture, LiDAR notes, and the upcoming app platform.
L298N is a popular, low-cost motor driver board. Here is how you can connect L298N to ESP32 and drive a ROS2 (Kaia.ai-compatible) differential robot. Schematic Wiring Refer to these wiring example illustrations. Firmware Use the default firmware with no changes.…
YDLIDAR X3, X3PRO, X2 and X2L are a low-cost 2D LiDAR 360-degree distance sensor used in robotics for navigation. Here are instructions to connect YDLIDAR X3/X3PRO and X2/X2L to the LiDAR port on Maker’s Pet BDC-30P and BDC-38P motor driver…
3irobotix Delta-2A, 2B and 2G are a low-cost 2D LiDAR 360-degree distance sensor used in smart vacuum cleaners for navigation. Here are instructions to connect Delta-2G to the LiDAR port on Maker’s Pet BDC-30P and BDC-38P motor driver and ESP32…
TB6612FNG is a low-cost driver IC for brushed DC motors – popular with DIY enthusiasts to build small wheeled robots. One TB6612FNG can drive two motors with power supply voltage up to 15V, average output current up to 1.2A per…
Kaia.ai firmware works with a wide variety of ESP32 boards, supports robots of different sizes, with various Lidars, motors, motor drivers and motor encoders – all thanks to a configuration file where you can specify your GPIO assignments. Configuring Kaia.ai…
Here are the most up-to-date and the most complete instructions to build, set up, bring up and operate Maker’s Pet BLD-120MM-PACK robot build pack with BDC-30P driver board. Finished Self-Driving Robot Demo As always, everything is open source. Robot Assembly…
Here is a DIY project I’d like to share. I’ve designed an adapter PCB to connect my LDS02RR Lidar to ESP32. I also wrote Arduino firmware to stream distance data live from LDS02RR – as well as many other low-cost…
ESP32 (and its DevKit boards) has a number of limitations with respect to its GPIOs. Here is a table of issues to keep in mind. The took the list of ESP32 GPIO limitations from a Randomnerd Tutorials post and added…
LDROBOT LD14P is a low-cost laser distance sensor. We have not yet evaluated its performance, but eyeballing this sensor’s output under indoor conditions makes us believe this sensor may have a reasonable performance. LDS Specifications According to LDROBOT LD14P specifications:…
