Opensprinkler bee code#
This book offers you that: Simply get into robotics with the Rasperberry Pi without prior knowledge Numerous illustrations, tables, circuit diagrams Information boxes with useful tips also for other Raspberry Pi projects Project code with syntax highlighting Two car projects: remote-controlled robot car via WLAN and self-driving car Hardware tips and recommendations for suitable accessories - Extensive project material as download: Raspbian image, parts list, chassis artwork and code Special features: Easy and robust cabling, use of high-precision time-of-flight laser distance measurement sensors, introduction to servo motors and suitable servo controllers, control via gamepad, use of an OLED display Your Rasbperry Pi driving instructor Ingmar Stapel studied computer engineering and is currently working internationally as IT project manager and enterprise technical architect in addition, he has been intensively involved with Raspberry Pi and robotics for years. The knowledge you acquire in this book will enable you to implement your own projects with the Raspberry Pi. With the acquired knowledge you can individualize and further develop your robot car as you wish. In the second part of the book, you will familiarize yourself with the sensors required for autonomous driving. You do not need any previous knowledge in robotics and programming.
Opensprinkler bee software#
An introduction to software installation and programming with Scratch and Python completes the first part. You build the chassis and wire the individual components - details can be found in the appropriate, richly illustrated chapters. In the first part of the book you will learn the basics of robotics and the interaction of hardware, electricity and software. download: Big Rob motor controller program L298NHBigrob.py Build your own robot car with the Raspberry Pi! Step by step to your own robot car This book guides you in two parts through the project phases with the aim of building an individual, autonomously driving robot car. This is important for wiring the motor driver. I uploaded the Python program with some inline documentation which describes which GPIO pins are used.

Opensprinkler bee driver#
That’s make it very easy for the Python control program to import the new BTS7960B Python program as an module and to control the motor driver without changing anything in the control program. BTS7960B Python program I had to re-write my Python program I already developed to control some L298N H-Bridges to control the BTS7960B motor driver. The picture below shows the wiring of the motor driver. The last two female-to-female jumper cables are needed feed the motor driver with a PWM signal to control the speed of DC motors (RPWM/LPWM).

Two wires are needed to activate each H-Bridge with a high signal generated by the Raspberry Pi to set the spinning direction of the DC motor (R_EN / L_EN). Two cables are needed to supply the logic of the motor driver with 3.3V (VCC and GND). Connecting the BTS7960B motor driver You need six female-to-female jumper cables to connect the motor driver with the Raspberry Pi. To make is easy for you to find the motor driver BTS7960B I used for my robot I added an Amazon online shop link.
Opensprinkler bee drivers#
The picture below shows the two motor drivers and the Raspberry Pi wired and placed on a cardboard inside my Big Rob. I decided to buy two BTS7960B motor drivers because they are able to supply a total of 43 A which is more than enough for my four dc gear motors. I found a motor driver with a total of 43 A and it could be controlled by a Raspberry Pi. I searched for a motor driver with more than 10 A on each motor out.
Opensprinkler bee upgrade#
Then I bought an upgrade for my Big Rob and now I am able to drive around and to turn on the spot without burning the motor driver. But this type of motor driver was too small at that point the robot tried to turn on spot the motor driver burned out. Big Rob – Raspberry Pi robot motor driver BTS7960B and Python program Build your own robot car with the Raspberry Pi! First I tried a small H-Bridge with 2.5 A to supply the DC motors with energy.
