Is it possible to combine mCore and robot arm?
I would like that my robot can move and in the same time have possibility to grab something.
But on mCore there are only 2 connectors for motor. And I am using it for running wheels.
Is it possible to add some component to connect 2 additional motors (one for gripper and anther for up-down motor)?
Hi,yes it is possible,but you need this adapter http://www.makeblock.com/me-rj25-adapter/ and a RJ25 cable to connect it to the board.It will work on any RJ25 port on the board,just make sure you select the correct port in the code.
Excelent…
So, I can use any port of mCore board. Connect it via RJ25 cable to MeRJ25 adapter. And from MeRJ25 adapter directly to gripper motor?
Gripper motor has only 2 cables. And MeRJ25 adapter has 6 pins. To which pins shall I connect gripper cables?
And how can I access it from software? We are using Scratch.
I guess with one of this commands?
"set servo Port Slot angle angle"
or
"set mini fan Port blow direction"
or something else?
Because “set motor motorID speed speedValue” alows me to select only motor 1 and 2.
Hey,I provided a pic of my simple code in which I use the provided IR remote to control the gripper (arm closed and open)
I also explained a little what and how it is connected and at bottom you can see how I wired my stuff.If you don’t understand something,feel free to ask 
Unfortunately, I do not have the same gripper arm as you (http://www.makeblock.com/mini-gripper).
I have “robotic arm” (http://www.makeblock.com/robotic-arm-add-on-pack-for-starter-robot-kit-blue).
Your gripper has 3 connectors.
My robotic arm has gripper with regular motor in it. And that motor has only 2 connected cables. So, I guess its work is handled by PWM and voltage polarity.
Among other parts, I got DC motor driver (http://www.makeblock.com/me-dual-dc-motor-driver). It has red mark on it. It should be connected between mCore and motor. But on mCore there is no red ports.
I see,this one seems to be made for Makeblock Orion board,not mCore.For mBot the gripper arm is different(the one on my picture)
