Conversely, if you already have an RCIC2_sc interface board and you are already running radio control, you can replace the RCIC2_sc interface board with a JSIC interface board and the included joystick adaptor cable. Then just plug any standard IBM compatible analog joystick into the adaptor cable and you're on local, tethered control. As in the above example, you now have the ability to choose either radio or tethered joystick control just by changing the interface boards.
For those of you who aren't interested in radio controlled robots, the JSIC is ideal for control of 2 motors with a single dual axis joystick. Like the RCIC2sc, it is programmed with left and right channel mixing. This means that, if the joystick is pushed straight forward, both motors will go forward at the same speed. Likewise for reverse. If you are going forward at some speed and you move the joystick to the right, the left wheel continues at the original speed while the right wheel slows down by a certain amount determined by how far the joystick is moved to the right. This will give you gradual turns right up to turning on center. At the 3 o'clock position on the joystick, the left wheel turns forward while the right wheel turns in reverse- both at the same speed allowing you to turn on center. The speed of the turn depends how far from center that you move the joystick to the right. Identical but opposite reactions if we were talking about left turns.
This is a great way to control load bearing vehicles for freight. It is NOT meant to be used for wheel chairs or other vehicles carrying people. As in the caveat given for the MC7 controller:
PLEASE NOTE: This system is meant for hobby robots or small to medium professional robots and light industrial applications. It is NOT meant to be used with electric scooters or wheelchairs because it has not undergone expensive FCC & FDA testing for EMI (radiated & susceptibility) and ESD required for use in these services. The MC7 which the JSIC controls is NOT WARRANTED as a fail safe device. As such, it should not be used in life support systems or in other devices where it's failure or possible erratic operation could cause bodily injury or loss of life.
The JSIC_SEP is the same interface programmed with NO MIXING for those of you who aren't steering robots but would like to do neat things like remotely control the pan and tilt of a camera or a satellite dish. One axis of a joystick controls one motor while the other axis controls a second motor without interaction. Be sure to specify the separate channel option when ordering or you will receive a JSIC with mixing.
The JSIC with joystick cable & connector assembly is $45.00.
