Hello,
I have developed a self-build, 3D-printed 'robot' dinosaur kit. It is not at all robotic to be honest -it's just a simple skid-steer toy, as shown further below.
It is presently controlled through a long 'umbilical' cable which is not really ideal and involves the user dealing with a lot of wires. So I am seeking advice about how to convert to an RC system.
More details below if you are interested...
The device moves using skid-steered rotating claws and the head/neck/jaws lunge and bite.
Two are shown fighting in the video below (an earlier design that used the motor from a cordless drill and was not 3D printed, but it functions in the same way).
There are four rotating claws. Those on one side rotate in the same direction and each side is controlled by an on-off-on, DPDT slider switch:
This provides simple skid steering.
In addition, a micro-switch is used to operate the biting-lunging action of the head and jaws operated by the trigger shown above.
The claws are rotated by 'economy' 6V motor gearboxes which have a built-in 200;1 gearbox.
Four such motors move the neck-head-jaws assembly using simple cranks:
The image below shows the assembled device with the controller and umbilical.
As you can imagine the long length of wires involved is annoying!
So I would value thoughts on how to convert it to an RC system. I have done a bit of research into possible off-the-shelf solutions, but they all relate to the use of servos rather than simple on/off switches.
One other issue is the electromagnetic 'noise' generated by the motors. Someone started looking into this for me and they were thinking of an infra red system but said that the amount of noise generated was a problem.
Ok, any help much appreciated -thanks in advance.
