Mechanics and Construction / Re: Robot wheel/omni Directional Wheel
« Last post by aika2016 on February 20, 2017, 03:05:59 AM »
Dear friends
I am working on a soccer robot for robocup competitions. I have found some interesting omni directional wheels for my robot which has some significant advantages. It is thinner and lighter than the most of the other omni wheels. Moreover it has a good friction and I could move my robot very easily and efficiently.
I want to suggest you to see these interesting omni wheel
the website is :

 does anyone have use them already?
Electronics / Trying to read battery voltage from ADS1115 to Raspberry Pi
« Last post by forcel96 on February 19, 2017, 06:56:16 AM »
Hi all. I have a solar powered Raspberry Pi setup and I am attempting to read the battery voltage from the battery to the Raspberry Pi. I am told that I should be able to accomplish this with an ADC. Unfortunately I have very little understanding of electronics and wiring so I am hoping to get a few pointers...

I have looked over this link already:

The main question I have is exactly where in my setup the ADC will fit. At the moment I have the following:
- 3.7V battery connected via 2-pin JST-PH to the USB / DC charger (
- USB / DC solar charger connected via 2-pin JST-PH to PowerBoost 500 (
- PowerBoost 500 is powering the Pi via USB cable.

So I am unsure of exactly where the ADC should fit into this setup. Would the ADC need to be wired to the battery, the Pi, and the charger? Would the ADC be between the battery and the charger, and then grounded to the Pi? Or is there perhaps an output from either the solar charger or the PowerBoost that I could connect to the ADC to get the battery input?

Any help would be greatly appreciated.

Software / Using a rotary encoder
« Last post by vinnygalbo on February 16, 2017, 01:15:27 PM »

The only 5 pin rotary encoders I have encountered used 3 for 'encoder' part and the other 2 pins were for a momentary push button in the shaft; I haven't seen one that names a 'CLK' signal etc. I'm trying to see activity in the serial monitor. The encoder in question is an Accu-Coder.

Thank you in advance for any help.
Electronics / Wireless boat for college competition
« Last post by ojastayal on February 13, 2017, 11:09:42 AM »
Hey everyone, so I'm participating in a competition in my college that's pretty simple but then again I'm a complete novice when it comes to robotics. I need to construct a boat that is capable of performing certain tasks. Last year I have seen people compete by making wired bots but that was extremely cumbersome to operate and required 2 people just to hold the wires. Hence my question for you guys is this -

I need suggestions for a Tx/Rx set (note that the Rx will be on a boat so preferably water resistant) that can offer me the following functionalities -
1) Running a propellor (controllable high rpm and reversible DC motor)
2) Controlling a rudder (servo)
3) Operating a winch (single low rpm but reversible DC motor). Will be carrying a load of about 100-150 g of weight (a magnet permanently fixed and a piece of iron that needs to be picked up)
4) Generating a stream of water (need help with this one). Needs to be able to direct a steady stream of water at a point (in order to tear a tissue paper fixed in a spot in one round and fill up a bowl placed 50 cm high in another round). I can manually change the direction of the pipe generating the stream between rounds so no mechanism to control stream direction needed.
Also need suggestions on the motors and servo as described. Please note that bot mustn't be bigger than 45cm * 15cm and I need flat clear space in the middle to carry a 4cm cube. I can handle the mechanical parts and bot creation/arrangement, just need help with the electronics.

I know I might be using very poor terminology but I honestly don't know better unfortunately though I'm very willing to learn. If possible, please suggest makes and models (preferably cheap and easily available) or correct terms that I could use to get what I need from a dealer. Also if you recommend any links for me to read, I shall go through those too.

Electronics / What Wheel encoders to buy?
« Last post by rahulrameshbabu on February 12, 2017, 02:17:52 PM »
I am building a differential drive robot and I need s wheel encoder kit that will fit on a 6mm shaft. Can you guys please post some links of encoders preferably under 30$?
Misc / article on the current state of autonomous cars
« Last post by Admin on February 10, 2017, 10:48:16 AM »
Anti-accident technology will become a requirement like airbags, and combustion engines will get replaced by fuel cells. The industry is threatened by increasing telecommuters and Uber/Lyft alternatives. I suppose Zipcar is a dead company? When insurance becomes cheaper for safer autonomous cars, that's when autonomous cars will really kick off.
