New Rash2 robot is almost ready

[George Fomichev]

Almost ready to mock four-wheel robot:

1) carried out the planned actions shemotehnicheskie

2) set up the router

3) to adapt the program to the robot MC RASH1

At the moment, the robot is controlled remotely from a tablet and is able to travel independently.

1) Submission 6B these kitaysike engines solved the problem of their thought and even the current model, in which only one pair of leads, it is felt.

But then, the integral stabilizer dressing up strongly heated, epic radiator bolts and nuts are not able to dissipate 3W to be allocated for mioim estimates))) 5 minutes, you can steer the robot, but then it is impossible to touch the radiator. The idea must be put second switching regulator and adjust it to 6B. The problem is that ... I did not have a second card. Or buy from us or order from abroad (up to 6 times cheaper).

2) On-board stationary sonar is not able alone to provide reliable control of the front space. Although it was not planned - the robot must be inspected periodically moving sonar. The same - control for low obstacles.

3) The movement of the platform with 4 wheels specific. The rear wheels - do not omni, so when the robot cleaner turns much hard and a motion vector pointing back. The robot is unlikely to turn around on the spot "outright". Therefore, the need to take account of the turns indicated specificity and enable encoders to align the motion vector. It would be nice to make all-wheel drive platform, but it does not fit into the current circuitry, as need another driver, two encoder and will have to abandon the microcontroller Arduino Nano in favor of mnogonozhkovogo or muddy multiplexers to expand the findings on the basis of the shift buffer and then ... we crawl out of the dimensional parameters. Therefore, in this type of platform is still a front-drive.

4) Predvoryaya question wiring board postings board - yes, it's an example of just one like to do. It is only permissible at the layout where to plant the PCB and make it impractical. In the prior art this is undesirable.

5) Additional features to implement: work with encoders, servos, sophisticated algorithmic work with two sonar.
