Hello everyone, Me and my friends are making a spider robot which walks with the help of the its 8 legs. The mechanism is based on the patent of joe klanns mechanism and its motion is according to the klanns. We have built all the mechanical components including gears also. The mechanical assembly is almost in completion. But we are facing problems in electronics and programming section, since we are unfamiliar with that area. We need to control the 2 dc motor for its 4 direction motion using anroid apps. To do that can you guys help us what components are best suited and what is their approximate cost of altogether electronics parts only( the lesser the cost,better option for us). Plus we are thinking of adding some features in our projects. So could you guys give us some ideas like adding gripper or something that can be useful. Thanks in advance.
You’ll need a microcontroller, dual motor controller and Bluetooth. Fortunately, one product has it all:
robotshop.com/en/dfrobot-rom … RB-Dfr-582
Note that it can handle 2A max, so we’re assuming the motors you are using are not too big.
You’ll need to either find an Arduino - Android app (which do exist) or create your own.
Either way, you’ll need to create some code to upload to the board. There is sample code available though which will help a lot.
Coleman is correct on electronics requirements, however from a quick look at the 'bot, it seems to me that you don’t really have any control. Unless I’m mistaken, the motors drive both sides, just forward/aft are split between motors. Correct me if it’s different then that.

thanks cbenson.We will search for that kind of circuit board in our market here. and yes we are using 200 rpm dc motor.
Alan KM6VV , yes the motor runs both sides.But altering the motion of each motor gives the desired left and right steer for the octapode spider robot. For example if the both motor is moves clockwise direction then the spider moves forward and if both runs anticlockwise then the spider runs backward. If the one motor runs forward and another motor runs backward then it will give necessery rotation for our robot which we are hoping.
