@thrandell Real world jobs have meant I have had to pack away the robot projects since the start of the Easter break until I get a break some time i...

@petertrad "Libraries that use AVR-specific instructions are not compatible with the architecture of UNO R4 boards. However, some of these libraries...

@thrandell I thought about doing something like that but forming spring steel ... If you look back in this thread my solution to that was to ...

@thrandell Looks good. Probably if I had a 3d printer I would just use the same bumper solution used by robot vacuum cleaners.One thought I had w...

@botbuilderuk That is the closest I have seen on the forum to Loki (Dave Shinsel) and Arvo (John Blankenship) and the kind robot I imagined building...

@zefd Maybe just run over low lying obstacles? Probably ultrasonic sonar sensors or IR sensors would both struggle to see a dark and fluffy cat :...

@winddance If you have checked the wiring for shorts or incorrect connections then it must involve the driver?That it worked and then stopped makes...

@winddance I redid all the tb6600 connections but nothing changed. I was thinking maybe something changed in the tb6600 internals (lost earth...

@huckohio The ros driver board look really good if you have a RPi5 It is a matter I guess of searching for a ROS based fully explained tutoria...

@huckohio Unfortunately I am completely unqualified to have any comment at all about using ROS.Ideally you need guidance from those who have actual...

@gameworn I couldn't find anything about ROV_Nisk1I assume they are Java error messages which I think the Processing Language uses.I can usually fig...

@smithdrewsmith Ok. Hard to give suggestions without fully understanding the setup. I assume by tactile switches you meant capacitive touch switc...

@smithdrewsmith Yes, I need to drive a simple motor at 12VDC. Yes, a button press would supply 12V to the driver as a signal to turn the motor ...

@smithdrewsmith It is unclear to me what you are alluding to? What is a "dumb" motor driver circuit? Does your project involve a simple DC 12 vo...

@inq As Dave explains you can shift a voltage up or down and magnify a voltage (amplification) using an OP amp or in ye old days a transistor. Bef...
