My first schema IOIO Robot with Fritzing

Hello,

I am novice, my IOIO Robot is composed by following items :
  • "IOIO-OTG" board 
  • Base robotic "OL1" with 2 Motor DC 6V
  • Bridge H L293D
  • Servomotor Dagu RS001 time motion. 60° @ 4,8V/6V : 0,10 s
  • Servomotor "Nano-S" time motion. 40° @ 4,8V/6V : 0,12 s/0,10 s
  • Infrared sensor SHARP™ "GP2YOA51SK"

Is it ok ?

Diagram
1. The GP2YOA51SK probably want to be powered by 5V.
2. Add some bulk and filtering caps.
3. What powers the beast?

A traditional schematic may provide more detail such as the L293D pin definitions.

The sharp consumes a lot of current when active.

Power : Accu Li-Ion 3,7 V 2000 mAh http://www.gotronic.fr/art-accu-li-ion-3-7-v-2000-mah-19034.htm like this Robot

Bulk and cap ? What do you mean ? sorry for my english.

You probably don’t want to

You probably don’t want to power the servos and motors from the board, but either directly from the battery, or through an additional non-linear voltage regulator with enough amperage. Those things can draw a lot of current, and the regulators on the board are linear (lower voltage by heating) and of limited power.

Let’s pray :wink:

Thanks all for yours advises

Normally, the power will come with this part : https://www.robotshop.com/letsmakerobots/ioio-robot-solar-cell-and-self-powering-0

I will receive my IOIO this evening and rest of Robot before the weekend… I will try, and pray it works !!!

Schematic
I find the schematic more informative. Is this an alternative output of the fritzing program? You need to improve the power distribution. I like to use fat red lines for positive power and fat black lines for negative (ground). Then a random assortment of colors for signals. Note that the LM393D calls for 4 ground connections, you have 2, and that you are using the internal connections to route ground to the rest of the circuit.

As others have stated you may need external voltage regulators and a power switch.

Capacitors impede changes in voltage. They can be used to store charge (bulk, ie 100uf) or filter high frequency noise (ie 0.1 uf). Most electrical circuits need both. The exact value can be calculated but most people just guess.

5V will be provide

5V will be provide through LiPo Rider Pro POW12059P (Single cell LiPos batteries will NOT work, you need a 5-10V input.)

need your help !!!

Hi friend,

Now I’m trying to make a simple (many many novice) bluetooth control robot. I think I can solve codes in android studio but my problem is connecting equipments.

in this step, I need to assemble;
- IOIO board,
- 2 dc motors,
- L298n motor drivers

How must I connect them? I saw some diagrams at the internet but I couldn’t make it. Could you please show me that?
