Rotary Tool

New in this version of FarmBot Genesis is the inclusion of the Rotary Tool - a weed whacker style tool powered by a 24V DC motor that is designed to help abate weeds, drill holes for seeding, or even perform light milling of the soil surface. The tool is powered by a stall detecting motor driver and is compatible with the Genesis UTM like all other tools. Users can change out the Rotary Tool’s implement to weed trimmer line or a drill chuck compatible with standard dremel tool bits. The axis of the motor can be adjusted +/- 70 degrees, allowing for a wide range of use cases.

v1.6 Farmduino

The latest revision of our custom Farmduino electronics board includes a new 24V motor driver to power the new Rotary Tool. This new output includes load detection circuitry allowing FarmBot to detect when the Rotary Tool has stalled due to overload. We have also increased the USB OUT voltage that supplies the Raspberry Pi to mitigate low voltage issues that have affected CPU, WiFi, and camera performance in past versions. Last, the board now includes a more appropriately specced 7.5A fuse instead of a 15A fuse.

Vacuum pump with EMI filter

The vacuum pump now features a circuit board directly soldered onto the back of the motor which performs EMI filtering and reduces the startup current draw of the motor. This circuitry will help reduce WiFi interference caused by the vacuum pump, as well the potential for the pump to drop the system voltage below acceptable levels when starting up. Additionally, the vacuum pump cable is now a shielded cable, with the shielding connected via a third quick-connect terminal to the vacuum pump motor’s housing. The shield is connected to PE (protected earth) at the Farmduino.

Thank you Réstep

The EMI filter circuit included on the back of the v1.6 vacuum pump is based on Chris Arntzen’s openly licensed Réstep EMI Filter add-on for older versions of FarmBot’s vacuum pump.

Thank you Chris for lending your expertise in electronics design to the FarmBot community with this fantastic open-source contribution!

Modularized UTM cable

Building on the progress made in v1.5, the v1.6 kit includes a two-piece modularized UTM cable, with one section running through the y-axis cable carrier and the other section running through the z-axis cable carrier. The two sections are joined by a 12-pin 90-degree waterproof screw-together connector. This makes assembly and disassembly of the FarmBot much easier because now all cables and tubing can be disconnected at the Y/Z cable carrier junction.

Smaller x-axis cable carrier

The x-axis cable carrier has been reduced in size to 15mm x 20mm internal dimensions. This saves significant weight and reduces friction when moving along the X axis. With this change comes new 30mm horizontal cable carrier supports and a new 35mm horizontal cable carrier mount, adding to overall material, weight, and cost reductions in the kit.

Pre-assembled tools

All tools (the Watering Nozzle, Seeder, Weeder, Soil Sensor, and new Rotary Tool) now come pre-assembled and packed individually in small boxes. This reduces the burden of FarmBot assembly required by the end user.

Updated power supply and power supply cable

The power supply is now slightly smaller in size. Additionally, the power supply cable is now a 3-core cable to provide PE (protected earth) grounding for the Farmduino.

Deprecated FarmBot Genesis MAX

Due to low demand, FarmBot Genesis MAX (introduced in v1.5) was cancelled and is no longer supported in the v1.6 documentation.

Miscellaneous

  • The camera cable is now manufactured with shielded USB 2.0 cable (28AWG/1p+24AWG/2c) to reduce intereference problems that affected some v1.5 installations.
  • Shortened the X1 motor cable and X1 encoder cable to reduce the amount of extra cabling underneath the electronics box.
  • Removed unnecessary features from the leadscrew block design.
  • Removed the 5.5mm wrench, 2.5mm hex key, bladed screwdriver and phillips screwdriver from the kit.
  • Updated some part quantities to reduce the number of extra pieces at the end of assembly.
  • Added numerous documented QA checks to our manufacturing processes.
  • Made improvements to the sustainability of packaging materials.
