Kitronik Bump and Spin Buggy Kit plus batteries
About the Buggy:
The Bump and Spin Buggy is an easy to assemble introductory kit which makes use of our Bump and Spin Kit to look at entry level robotics and allow you to quickly and easily make a working wall-sensing buggy. By following the step-by-step instructions (below) and downloading the sample program, you can program the buggy to your own specific requirements and get the buggy running in no time!
The buggy is a robot that is aware of its surroundings. Using two strategically placed microswitches the buggy is able to detect when it hits a solid surface, allowing it to 'bump and spin' to avoid obstacles.
A PICAXE USB Download Cable is required in order to program the buggy.
About the PCB:
The chassis of the buggy has been designed to take the hassle out of designing a buggy, is quick and easy to assemble and includes an easily accessible on/off switch. The buggy is based on the programmable PICAXE 08M2 chip and includes the DRV8833 Motor Driver IC which is able to drive two 6V motors bi-directionally. The motor driver IC is pre-mounted on the PCB, leaving the remaining capacitors, resistors and other components to be soldered to complete the kit. The bump and spin buggy takes care of the mechanics so you can focus on the electronics and programming it!
Programming the Buggy:
The kit is supplied with a 3.5mm stereo jack for programming. When programming the board a small slide switch needs to be set to 'PROG' and on completion be set to 'RUN' (This is done to make full use of the microcontroller IO pins). The input pads have a pull down resistor and a de-bounce capacitor allowing a switch to be connected to the board and the PIC programmed to respond to it with the minimum effort. The motors are driven by the DRV8833 motor driver IC which is pre-mounted on the board, this will drive 1.5A motors so has plenty enough power for most projects. The kit is supplied with a 4xAA battery cage to power the board.

Hi Ben, I haven’t heard of this before so it is a little odd. I know the PICAXE IC has to have power supplied to it via the device it is plugged into such as the bump and spin kit. It could also be the software version you are using, check to see if the IC you are using is listed in the drop down list of the IC’s you can program to. Failing that PICAXE may be able to provide better help on this as I suspect it could be software related.
Hi Ali, You would need to use a PICAXE software, you can download one for free here, http://www.picaxe.com/Software
The code is provided on the product page, you just need to download it and install on your BBC micro:bit.
The kit includes everything you require for the kit, the only items you would need to purchase alongside are the batteries for the cage, and the download cable to enable you to program the PICAXE chip using the PICAXE software.
