"I got a new graphics card but the framerate was terrible, and the manufacturer's website didn't help at all. It turns out that the driver that came with the card was 6 months out of date! Driver Robot got me the latest driver automatically, and now my whole system is more responsive, especially the games."
Printer issue resolved
"When I upgraded to Vista I didn't want to throw out my perfectly good old printer, but I wasn't having any luck finding Vista support for it. I gave Driver Robot a try and it identified my printer and installed a special Vista driver from its database - my printer works like it always has, and I saved $200, so I'm pretty happy."
New life for an old PC
"I had an old Pentium III kicking around that I wanted to put XP on for the kids. Instead of finding each driver one by one I used the Driver Robot exporter and got the whole system set up in about 30 minutes. Money well spent, especially since I can do it again any time."

How to Upload File in Selenium Webdriver Using Robot Class
Famed hacker George Hotz has been developing a driver-assistance system, which can retrofit existing vehicles (with Level 2 autonomy), for a number of years now. However, we haven't been afforded a demo of the technology since 2015, when the company ran into regulatory issues with the US government. But with Friday's update release of Openpilot 0.5, the company's open source autonomy software, Comma.ai was back on the roads, taking Engadget for a spin to show off the system's new bells and whistles.
"We don't work with Honda," he quipped during the test drive. "We work with Honda products."
Openpilot 0.5 offers a number of updates, the most exciting of which is its facial-tracking ability. In the last iteration of the dev kit, the driver assist would only operate for six minutes at a time -- long enough to be useful but not long enough for you to tune out entirely. The new version, however, will track the driver's face to ensure that they keep their eyes on the road. As long as you remain facing forward, the system will work for as long as you need it.
The company is also releasing a crowdsourced tracking tool called Comma.ai Explorer. Since the driver-assist feature is still undergoing development and being taught to avoid specific driving mistakes, the company encourages its users to not only upload their drive telemetry data to the Comma.ai servers but also annotate any "disengagements" (incidents when the assist had to return control to the driver) that the team uses to further improve the system's reliability.
Comma.ai's driver-assist system uses the same Panda ODB sensor, Giraffe bridge and EON dash cam hardware that we've seen before. The only things missing from the newest hardware iteration is Waze and Spotify, which were removed "to free up resources for larger models and precise localization," according to the company's Medium post.
The driver assist is compatible with virtually every new Toyota and Honda on the market (they just need to have a trim package that includes radar sensors) as well as select GM models -- including the SuperCruise-enabled Cadillacs.
Our test drive was ridiculously smooth. We took it for a 20-minute trip down the I-280 South in light to medium traffic. Once engaged, the Comma.ai drove flawlessly. All I had to do was engage the Honda Civic's cruise control and set my desired speed using buttons on the steering wheel. Once the driver assist took command, it automatically accelerated, braked and steered as needed to keep the vehicle in the center of its lane, a safe distance from the cars around it and keep up with the flow of traffic. It even maintained a super-safe 1.8-second gap behind the vehicle in front of it and automatically adjusted its position among the surrounding cars as they changed lanes.
Never once was I nervous about how the AI system was functioning, there were no abrupt speed changes, lane changes or other hiccups. The only time I had to take over control was when I intentionally exited the freeway. Honestly, this Comma.ai system is a better driver than I am, especially in heavy, stop-and-go traffic. My only responsibility was to keep my eyes on the road. If I looked down or to the right (as if I were looking at a something on the passenger seat) for more than 2 seconds, a visual alert would trigger on the dash cam unit. If I kept looking away for 4 seconds, an audio alarm would sound, and if I didn't return my gaze to the road within 6 seconds, the driver assist would automatically disengage and begin decelerating the vehicle. It'll still steer and brake as needed as it slows, but you'll have to take control of the car before you can re-engage the assist.
What's more, if you get caught looking away for more than 6 seconds on three separate times during the same trip, the assist will disengage and lock until you stop and restart the car. Similarly, the system will shut down if you open the driver-side door or unclick the driver's seatbelt.
Comma.ai offers the necessary hardware through its web store (though you can also grab the Panda on Amazon), which can be installed in compatible vehicles in under 10 minutes with minimal tools, as you can see in the video above. The software that controls everything needs to be downloaded and installed separately (it's a regulatory thing) but is free from Github and, since the EON dash cam is really just an Android OnePlus 3 running inside a custom 3D-printed case, that installation is as easy as sideloading an app. There are also a host of YouTube instructional videos available to guide the process as well.
The entire system is still in beta and is geared more towards early adopters and enthusiasts -- so this isn't something you're going to want to surprise your tech-phobic parents with just yet. Don't worry, the company is reportedly hard at work developing an all-in-one consumer offering Internet download manager 6 12 with Patch

Generally, even the simplest robot requires a motor to rotate a wheel or performs particular action. Since motors require more current then the microcontroller pin can typically generate, you need some type of a switch (Transistors, MOSFET, Relay etc.,) which can accept a small current, amplify it and generate a larger current, which further drives a motor. This entire process is done by what is known as a motor driver.
Motor driver is basically a current amplifier which takes a low-current signal from the microcontroller and gives out a proportionally higher current signal which can control and drive a motor. In most cases, a transistor can act as a switch and perform this task which drives the motor in a single direction.
Turning a motor ON and OFF requires only one switch to control a single motor in a single direction. What if you want your motor to reverse its direction The simple answer is to reverse its polarity. This can be achieved by using four switches that are arranged in an intelligent manner such that the circuit not only drives the motor, but also controls its direction. Out of many, one of the most common and clever design is a H-bridge circuit where transistors are arranged in a shape that resembles the English alphabet "H".
As you can see in the image, the circuit has four switches A, B, C and D. Turning these switches ON and OFF can drive a motor in different ways.
- Turning on Switches A and D makes the motor rotate clockwise
- Turning on Switches B and C makes the motor rotate anti-clockwise
- Turning on Switches A and B will stop the motor (Brakes)
- Turning off all the switches gives the motor a free wheel drive
- Lastly turning on A C at the same time or B D at the same time shorts your entire circuit. So, do not attempt this.
H-bridges can be built from scratch using relays, mosfets, field effect transistors (FET), bi-polar junction transistors (BJT), etc. But if your current requirement is not too high and all you need is a single package which does the job of driving a small DC motor in two directions, then all you need is a L293D IC. This single inexpensive package can interface not one, but two DC motors. L293, L293B and few other versions also does the same job, but pick the L293D version as this one has an inbuilt flyback diode which protects the driving transistors from voltage spikes that occur when the motor coil is turned off.
Introduction to L293D IC
L293D IC generally comes as a standard 16-pin DIP (dual-in line package). This motor driver IC can simultaneously control two small motors in either direction; forward and reverse with just 4 microcontroller pins (if you do not use enable pins). Some of the features (and drawbacks) of this IC are:
- Output current capability is limited to 600mA per channel with peak output current limited to 1.2A (non-repetitive). This means you cannot drive bigger motors with this IC. However, most small motors used in hobby robotics should work. If you are unsure whether the IC can handle a particular motor, connect the IC to its circuit and run the motor with your finger on the IC. If it gets really hot, then beware... Also note the words "non-repetitive"; if the current output repeatedly reaches 1.2A, it might destroy the drive transistors.
- Supply voltage can be as large as 36 Volts. This means you do not have to worry much about voltage regulation.
- L293D has an enable facility which helps you enable the IC output pins. If an enable pin is set to logic high, then state of the inputs match the state of the outputs. If you pull this low, then the outputs will be turned off regardless of the input states
- The datasheet also mentions an "over temperature protection" built into the IC. This means an internal sensor senses its internal temperature and stops driving the motors if the temperature crosses a set point
- Another major feature of L293D is its internal clamp diodes. This flyback diode helps protect the driver IC from voltage spikes that occur when the motor coil is turned on and off (mostly when turned off)
- The logical low in the IC is set to 1.5V. This means the pin is set high only if the voltage across the pin crosses 1.5V which makes it suitable for use in high frequency applications like switching applications (upto 5KHz)
- Lastly, this integrated circuit not only drives DC motors, but can also be used to drive relay solenoids, stepper motors etc.
The circuit shown to the right is the most basic implementation of L293D IC. There are 16 pins sticking out of this IC and we have to understand the functionality of each pin before implementing this in a circuit
- Pin1 and Pin9 are "Enable" pins. They should be connected to 5V for the drivers to function. If they pulled low (GND), then the outputs will be turned off regardless of the input states, stopping the motors. If you have two spare pins in your microcontroller, connect these pins to the microcontroller, or just connect them to regulated positive 5 Volts.
- Pin4, Pin5, Pin12 and Pin13 are ground pins which should ideally be connected to microcontroller's ground.
- Pin2, Pin7, Pin10 and Pin15 are logic input pins. These are control pins which should be connected to microcontroller pins. Pin2 and Pin7 control the first motor (left); Pin10 and Pin15 control the second motor(right).
- Pin3, Pin6, Pin11, and Pin14 are output pins. Tie Pin3 and Pin6 to the first motor, Pin11 and Pin14 to second motor
- Pin16 powers the IC and it should be connected to regulated 5Volts
- Pin8 powers the two motors and should be connected to positive lead of a secondary battery. As per the datasheet, supply voltage can be as high as 36 Volts.
I have shown you where to connect the motors, battery and the microcontroller. But how do we control the direction of these motors Let us take an example:
Suppose you need to control the left motor which is connected to Pin3 (O1) and Pin6 (O2). As mentioned above, we require three pins to control this motor - Pin1 (E1), Pin2 (I1) and Pin7 (I2). Here is the truth table representing the functionality of this motor driver.
High ~ 5V, Low ~0V, X=Either high or low (don't care)
In the above truth table you can observe that if Pin1 (E1) is low then the motor stops, irrespective of the states on Pin2 and Pin7. Hence it is essential to hold E1 high for the driver to function, or simply connect enable pins to positive 5 volts.
With Pin1 high, if Pin2 is set high and Pin7 is pulled low, then current flows from Pin2 to Pin7 driving the motor in anti-clockwise direction. If the states of Pin2 and Pin7 are flipped, then current flows from Pin7 to Pin2 driving the motor in clockwise direction.
The above concept holds true for other side of the IC too. Connect your motor to Pin11 and Pin14; Pin10 and Pin15 are input pins, and Pin9 (E2) enables the driver.
I guess we have already had too much of theory. In the next section, we will start building the board.
