RV2 robot

My latest robot, built with an Arduino Nano v3, plugged into a 400pin breadboard. Ultrasonic distance sensor, Sharp IR distance sensor, Laser, PIR motion detector, Piezo speaker, and IR Receiver (accepting commands from a TV remote). Servo to turn the head. Moves around avoiding obstacles, firing laser, beeping, detecting if a human is around, and responding to commands from the remote. Pleased with this, but want to give it more advanced programming. Would like to combine it with a Raspberry Pi acting as a brain (when I get round to that).

Estimated costs of construction

Estimated Costs are here:

PARTS:
4x geared motor = £4.00
4x wheel = £4.00
1x lunchbox = £1.00
1x Arduino Nano v3 + usb cable = £2.50
1x 400pin breadboard = £1.20
Various nuts and bolts = £0.50
Various wires = £0.50
Ultrasonic HC-SR04 dist. sensor = £1.20
Sharp IR distance sensor = £3.50
IR Receiver = £0.25
Double-sided tape = £0.50
Shrink-wrap = £0.25
PIR motion sensor = £0.75
Laser Diode = £0.20
Piezo Buzzer = £1.00
Lipo Battery 7.4V = £8.00
Motor Driver Board = £2.00
Tower Pro MG90S Servo = £3.00
Servo holder = £2.00
-------------------------------
TOTAL = £36.35 ; 46 Euro ; $58
-------------------------------

TOOLS
3x Screwdriver = £3.00
1x Wire Stripper = £5.00
1x Soldering Iron = £10.00
Lipo Battery charger = £8.00

In my case I already had the Lipo battery and charger (model helicopter), I had a piezo buzzer from a pc motherboard, suitable wire can be reclaimed from CAT5 ethernet cable, and various items I bought in bulk to save money and plan to use them in other projects. Ebay and Chinese vendors helped keep prices as low as possible. Note that prices in UK are not so good for buying electronic components and parts.

Welcome to LMR. Nice little

Welcome to LMR. Nice little robot. I like the laser feature and the choice for the chassis :slight_smile:

**Looking good so far! **

Lokks like a fun little bot.  What is your purpose for having both Ultrasonic and IR sensors on the same mount?  Are you blending (planning to blend) the results for better accuracy?

 

IR command with servos and ping
Looks like you have managed to overcome a key challenge i’m facing with arduino. When i try to combine servo, ir and ping libraries i get errors to do with the timers and loose the pwm outputs i’m using to drive my h-bridges. Does the nano help deal with this issue?
I am working on my first project with my son - a Dr Who K9 built on a hacked big trak motor chassis and board, arduino brains, hcsr04 distance. Want to add IR override but found i get garbage signals. Very much a beginner!
Many thanks for any suggestions.
