We are making progress on our build, so to update our previous to do list is as follows;
Convert the battery charger to a XT60 connection - Done
Remove the existing radio controller and esc - Done
Connect the cars steering servo to the Ardunio and onto the RPI -Done
Find a new esc - Brought a Hobbywing QunicRun ESC, we needed to re-wire the connections but seems to working
Connect the esc to the Ardunio and onto the RPI - Done, we are powering the servo from the ESC output
Build a mounting platform for the RPI, Ardunio and power supply - Still to do
So we have made a good start to the build of Roblucks. This is the first time we have tried using an Ardunio and so far so good. At the moment we have the wheels running at a constant speed and accepting a one letting command from the PI to turn the wheels left, right or centre from a serial USB connection.
As the name of the post (belovedly stolen from Star Trekkin') suggests we need to work out how to reverse the motor through the ESC is at the top of our next to do list which looks something like;
Find reverse
Connect the PI to the Ardunio via I2C
Power the Ardunio and PI via batteries
Build a mounting platform for the RPI, Ardunio and batteries
Translate PI wireless controller commands into movement controls
