I should doa tutorial video for the rover. I'll do it next week

Hi Mago,

I've implemented the EZ-B with the online store's tank chassis. Using the H-Bridge as shown in this video: https://synthiam.com/Community/Videos/Default.aspx?id=XM2jjsDPvJY

I purchased and use the jumper wires instead of soldering though.

I use the movement controller and the camera controller which is awesome!

Video controller below: https://synthiam.com/Community/Videos/Default.aspx?id=fmZGPqD42Z4

Here's the script from the H-Bridge controller that moves it in a square: $fwrd=2000 $turn=1200 #forward 1 sec and stop #Right Track Forward #set(d16,on) #sleep(1600) #set(d15,off)

#forward set(d16,on) set(d15,off) set(d19,off) set(d17,on) sleep($fwrd) set(d16,off) set(d17,off)

Right Sharp Spin

set(d15,on) set(d19,off) set(d17,on) set(d16,off) sleep($turn)

#forward set(d16,on) set(d15,off) set(d19,off) set(d17,on) sleep($fwrd) set(d16,off) set(d17,off)

Right Sharp Spin

set(d15,on) set(d19,off) set(d17,on) set(d16,off) sleep(1250)

#forward set(d16,on) set(d15,off) set(d19,off) set(d17,on) sleep($fwrd) set(d16,off) set(d17,off)

Right Sharp Spin

set(d15,on) set(d19,off) set(d17,on) set(d16,off) sleep(1250)

#forward set(d16,on) set(d15,off) set(d19,off) set(d17,on) sleep($fwrd) set(d16,off) set(d17,off)

Right Sharp Spin

set(d15,on) set(d19,off) set(d17,on) set(d16,off) sleep(1250)

Here's a link to my program that includes the 6 axis robotic arm and camera controls: https://synthiam.com/Community/EZCloud/Download.aspx?id=171

Best,

@EEGbiofeedback if you have the HBRidge control connected to the robot, you do not need to SET commands. Simply use "Forward()" and "Left()" and "Right()" and "Stop()" and "Reverse()"

For example, to do a square:

Forward()
sleep(2000)

Left()
sleep(500)

Forward()
sleep(2000)

Left()
sleep(500)

Forward()
sleep(2000)

Left()
sleep(500)

Hi guys!, thanks for your help.

That video shows the connection between to boards, but I need to connect the rover chassis with the ez-b directly?. The rover has a cable with just two colors, red&black, and a bigger input. The ez-b has three pins smollers, so, the problem is that those connectors do not fix with the ez-b's pins. I'm attaching images. All this issue exist under the idea that I do not need to buy another board to control de rover chassis?, is that ok?, or I need to buy the board showed on the video to control the rover chassis?.

Best.

Thanks for the tip DJ. That simplifies things considerably!

Mago,

In reading through the forum I saw others using the H-bridge board when running motors that are reversible. But I don't see why the digital ports couldn't power the motors to move forward and turn one track at a time. However the H-bridge enables reversing polarity so that the motors can turn in opposite directions on a dime and for the tank to move in reverse.

To use the digital ports just to get the thing moving, you should be able to add 2 servo controls for each motor. Then connect your red wire to the digital port D0 and the black to ground. Then do the same for the other motor. If you bought the jumper wire bundle, you could insert a tinned wire into the positive hole on your motor power plug and the double female jumper wire from that positive wire over your d0 port etc.

Then when you activate the control it should start spinning. If the servos don't work try adding a digital control would be more likely turn the motors on but just full speed. Or maybe not.

Best,

Bill

Microcontrollers do not provide enough power for motors - You can read more in the EZ-B manual: https://synthiam.com/Manual

OK, thanks to you both. So, I need and extra board to run the chassis, I didn't know that, I thought that the ez-b and the rover chassis were enough to start to move my robot over the floor. In order to move formard, what I need to move the chassis, what model of board?, etc., I already know the video which explain the conection between ez-b + board + chassis, but I need to know what to buy. Thanks in advance.

The 2.5 amp motor controller in our store

I'll make a video to be clear for anyone in the future. So much to do! So little time

You can make that rover 4wd by getting two rovers and rob the motors from it. Super easy a 10 yr old would have it done in ten min. I tested the rover 5 with 30 pounds on it with mine running 4wd, no more than 20 pounds and the rover is still fast.

@jstarne so would i be able to do it because im 10 lol

@daradu yes you should be able to do it , just have parental supervision when soldering and double check all your connections you have made with djs video before applying power. -Josh S

@jstarne1 dagu has a few models of the rover 5, including one with 4 motors and four encoders. i know that ez-robot can order these for you also, but im not sure if thats common practice. either way the 4 motor with encoders model is much cheaper than buying a second rover to pilfer parts from. -Miles

I have purchased the 4 motor option before. The reason i suggest the pilferage of parts is you have spares in case you mess something up or want to make a change ect. I know when I mod bots there is usually cutting involved lol.
