The __KR01__ Robot is a [small robot|RobotWeightClasses] inspired by David P. Anderson's [SR04] robot. There's a series of articles describing the KR01 robot on the NZPRG blog, see ''[The KR01 Robot Project|https://robots.org.nz/2019/12/08/kr01/]''.

The cost of this robot is likely too high to be considered as a prototype for the NZPRG (though it'd be possible to reduce costs, see below), so [I'm|Murray] also designing several other lower-cost [robot prototypes].


!! Requirements

[{Image src='attach/KR01/early-chassis-rear-thumb.jpg' link='attach/KR01/early-chassis-rear.jpg' caption='KR01 Chassis - Rear View' align='right' class='imgFloatRight'}]

The following requirements are modeled upon David Anderson's [SR04] robot:

# to be able to navigate and survive in a normal (cluttered) household environment, without getting stuck
# to provide a robust and reliable platform for developing navigation and behavior software
# be entertaining, aesthetically-pleasing, and inspiring for the local human population 

Additionally, it is meant to explore [Murray's Thesis|MurraysThesis], which requires the development of a multi-threaded Python robot controller that includes a PID Controller, ultrasonic , LiDAR, IR and bumper sensor behaviours. ''Can it somehow learn?''


!! Specifications

[{Image src='attach/KR01/MiniTFT-1-thumb.jpg' link='attach/KR01/MiniTFT-1.jpg' caption='Mini TFT Display on the KR01' align='right' class='imgFloatRight'}]

* OSEPP Tank Kit chassis with either silicon tank treads or four silicon tires
* four OSEPP 9.0 volt 185 RPM motors with 1:45 gear ratio


! Minimal Option

The KR04 has a lot of features, and therefore costs. The current expenditures, which includes sensors, components and hardware that may possibly not even get used (hey! it's an ''experiment''), is probably nearing NZ$1000.

If you wanted to get started on a lower budget you could begin with the basic OSEPP Tank Kit, some kind of [robot controller] (an Arduino, Raspberry Pi, whatever), a [motor controller] (RobotShop has some dual motor controllers starting under US$5, with many on the [market|Vendors]), and power the robot using a commonly-available USB battery. With a mechanical bumper made from lever switches it'd be possible to build this for under NZ$200.

Here's a start for around NZ$170:
* [OSEPP Tank Kit|https://www.robotshop.com/en/tank-robot-platform-kit.html] : US$100 (RobotShop)
* [Raspberry Pi Zero W|https://www.adafruit.com/product/3400] : US$10, AdaFruit
* [Maker Drive H-Bridge Motor Driver for Beginner| https://www.robotshop.com/en/maker-drive-h-bridge-motor-driver-beginner.html] : US$3.73 (RobotShop)

...you'd still need to add a battery, some sensors and miscellaneous parts. And of course, don't forget to include shipping costs in your budget!
