Well it happened again, no updates here for sometime but another new project started!
Some work over the last couple of weeks, albeit small. I have now added a 9v power connection, so that I can develop code while connected to a power brick. Also added a connection panel to the rear of the robot, this allows better connection to the Arduino and reset switch.
Added some simple mounts for three reed switches. These are then connected to an analog pin via a resistor ladder. I have created some simple code that stops the head from turning once the magnet has reached a switch, this should allow for some testing of head position and mounting.
Once this part is finished, it will time to create a simple program to allow Hero Jr to be driven. Now that I can telnet to the Z80 this should make things easier.
As lockdown now starts to ease, updates on this project may not be as frequent. I do feel that this robot has much scope as a development platform, much like the original bots. I have lots of ideas, and development of the head including an input panel and LEDs will be next.
A little more 3D printing and the basic layout for the head is complete Need to workout how how to find the forward position. Running out of pins on the Arduino!
New motor arrived today, although much smaller than the original the gearbox really helps. Made up a quick adapter plate from some scrap aluminium. Seems much better, will now replace the rear sensor from a micro switch to an optical sensor. This should help as the micro switch was not being reliably triggered.
The RC2014 has now moved it to it’s new home. Much work now need to be done on tidying the wires to motor control boards and the Arduino.
