KATHI control box
Showing off my control box for my KATHI robot. Still a long way to go, but it's going. I need to 3D print the bezels and put them on to neaten up the controls. There's the Bluetooth transmitter, joystick, voice recognition module with speaker and mic, a little OLED status readout, and the sliders to control the robotic arm (MeArm). I can't seem to get my nRF24L01s to work (I think one of the units is bad. It stopped working after I hooked it up to a Mega and then it wouldn't work on anything), so I opted to go with two-way HC-05 communication. I don't like it as much, no real range and disconnects all the time. I'll change it back to radio as soon as I get my new nRF24 units.
Nice build. Thanks for sharing.
Ordered two new nRF24L01 and now everything is working great! Printed and placed the bezels and things are looking better.
