Diy Robot Chassis Driver A ULN

An XBee Explorer Regulated board An XBee Pro 60mW board with antenna A joystick An LED A 220 ohm resistor Two miniature switches A plastic box Well its quite simple and can be done in many ways.

After many experiences, Im in a point where I think I have achieved great results and thats why Im posting this instructable.

The robot is a resistant and easy to build chassis made of Actobotics aluminium channels.

Thanks to these channels we can get a great robustness and a reduced weight.

I choose six wheels using six motors that give them a great traction.

They give the robot a tank like movement that greatly simplifies the traction.

Great wheels give it the off-road features and the shock absorptioncushioning capability of this kind of vehicles.

The brain of everything is an Arduino board that controls all the electrical part, with a great power and able to control the extensions that may be added in the future.

The remote control is implemented using Xbee modules that are easy to use, providing a great security and a long range more than enough for a possible future experience of driving by watching its front video, FPV.

Repeat again for the other side (light blue points) - Join the sides using the pieces of aluminium channel you cut previously (7 12) (red points) - Screw the motors to the mounts with the shaft as low as possible as in the picture.

Join the structure with the aluminium plate, using the separators, and using bolts or nuts depending on type of separators (magenta points) Add Tip Ask Question Comment Download Step 4: Electronics I, Brain and Receiver.

I am hoping that you have a basic experience in electronics, anyway it is hardly necessary to use the solder.

This element is not absolutely necessary, but it is convenient for later extensions.

For the current assembly, it can be replaced with a simple switch capable of handling at least 10 amps.

A Regulated XBee Explorer board An XBee Pro 60mW board with antenna A Sabertooth board 12A dual motor driver A ULN 2803 and IC socket To facilitate the mounting, begin by releasing the aluminium plate of the chassis.

Draw on the aluminium plate three axes corresponding to the axes of the motors (red color) Place the 3s lithium battery in the middle of the first two red axes and three electrical contacts tab.

Be careful with the position, try to place the usb connector right in the middle of the two red axes at the right side, in order to access the usb connector from outside comfortably between the wheels and be able to program the board whenever necessary.

Attach the board with six bolts and set two nuts to each bolt in order to separate the aluminium plate.

Finally, place the sabertooth board at the same level with the aluminium plate using four bolts and nuts.

Plug the receiver module XBee on the Explorer Regulated board and make the four required connections: 5v to 5v, gnd to gnd, Din to TX3 (pin 14) and Dout to RX3 (pin 15).

Finally, using a piece of printed circuit islets, construct the circuit that controls the front LED lights, as in the scheme in the drawing.
