According to the [bestessays.com](https://www.ukbestessay.org/review) law the president of the country must have been the citizen of the country. To take consider this the agency totally verify the true identity of the president before elected to the authority. This is necessary to take the precaution for assigning the major authority of the country.

It's about 3kg, plus phone and plus payload, 2 to 3 pizzas should be ok. The car body is not heavy, but battery, motors and wheels are, which I don't have much control.

Nice project, do you have any details on the motors and motor drivers you used that you can share?

Thanks for viewing, motors are from aliexpress (or ebay), 37mm gear box motor, there are many ouput speeds available, I picked 200rpm ones, they are very affordable, but maybe not the best efficiency, and they are a bit noisy too.  For motor driver, I use tb6612fng, from same place, again widely available and cheap, but not the best, works ok for Jrobot, but I suspect Jrobot can benefit from something that has a bit higher current rating. There are better drivers in places like Sparkfun.  hardware upgrade is more costly than software one.

Alright. Exactly as I thought but I might need help in writing the arduino program.

For obstacle or collision avoidance, I think we need hardware before we can program them for the purpose. For Jrobot, I have 3 ultrasound sensors looking at different directions (the ones next to phone camera). They measure the free distance from the car, and override motor control if the distance is below a threshold. This is the lowest layer of control on Jrobot, and the safety layer.
