Powering The Pi Zero on UKMARSBOT

In this month's presentation, Ian Butterworth describes how he managed to fit a Raspberry Pi Zero to the UKMARSBOT while ensuring that there is enough power for everything. UKMARSBOT was designed to have a replaceable processor. What we didn't think of was adding a Raspberry Pi Zero as a supervisory…

UKMARSBOT Mazerunner

The UKMARSBOT robot was designed from the start to be a good training robot for aspiring micromouse developers. In this month's presentation, Peter Harrison describes some of the important considerations and features needed in the code that controls a micromouse. All the code that is described can be downloaded from…

Half size line – full size robot

We have been looking at the possibilities for a half size line follower challenge and Duncan has published a test track for printing in A1. I thought I’d see just how few special items were needed to try this out. So I used my A4 printer in posterising mode to…

I2C Sensor Controller (ISC) for UKMARSBOT

The purpose of the ISC project is to offload sensor control to an embedded controller which communicates over an I2C interface to the UKMARSBOT MCU. The ISC comprises a programmed ATtiny814 acting as an I2C Slave on a PCB which plugs in between the UKMARSBOT sensor board connection and cable…

Derek and Jim have a new half-size micromouse

Back in the late 20th Century, the micromouse contest we new and all sorts of designs were tried. Moderm micromouse designs have tended to converge but Derek and Jim, for their first half-size micromouse decided to made a new, and tiny, version of a classic - Thumper. Thumper had two…

A Raspberry Pi Pico based UKMARSBOT

I wanted to build a UKMARSBOT line follower but code it in Python. So here I describe how to replace the Arduino Nano with the recently launched Raspberry Pi Pico. The Pico is not ideal in many respects, particularly because it only has 3 A to D ports, where we…
