Getting started

How to get you machine first set up and driving

Written by Marcelo Scatolin Queiroz

Most Amiga Flex are crated and shipped ready to be used, but some of the details might differ from your specific machine, but the concepts are applicable to all.

The typical Amiga Flex shipment contains:

  • The Amiga Flex assembly

  • 2x Battery packages

  • 2x Battery chargers

  • 1x Remote Controller

  • 1x Remote Controller Charger

Batteries

Typically, the battery holders are located in the center rail, but can be placed on different location on the robot. Make sure you have the correct set of keys and the lock is retracted to receive a battery. Slide one or two batteries on the holders.


Secure the batteries using the provided keys. Each key is coded to its battery holder. Keep one of the keys on a safe place and contact our support team case you lose your keys.

IMPORTANT

Vibration during normal operation or transport can make the batteries slide of the holder and fall, causing accidents. Make sure your batteries are secured all the time they are on the robot.

Short press the red button on one of the batteries to turn the robot ON. Each battery have an indicator of its state of charge:

LEDs

Description

Less than 20% of charge. Plan for recharging or battery swap.

20% to 39% charge left.

40% to 59% charge left.

60% to 79% charge left.

80% to 99% charge left.

Battery fully charged.

You can also watch both batteries charge state on the dashboard screen.

For shutting down, press and hold the red button for 6s.

Alternatively, you can turn the Amiga Flex ON and OFF using the blue button on you control center, just like the battery buttons.

Charging

We ship out batteries with some charge, but recommend customers to fully charge them before each use. To start charging, uncap the charging port and connect the provided charger. You can charge the batteries both inside and outside the robot.

PRO TIP

If you connect your charger with the robot ON, both batteries will be charged. Just make sure the robot is in E-STOP to avoid it moves while connected to the charger.

The charger LED will flash GREEN while charging. A solid green light means the battery is fully charged, and solid RED light means there is a fault. Disconnect and reconnect the charger.

First drive

The Amiga Flex uses the dashboard and two beacon lights to communicate its state of operation. The main beacon is originally located over the front, left fork, but can be moved as needed. The secondary beacon is located next to the E-STOP and ON/OFF button at the control center. The following states are supported:

Beacon lights

Description / Action

Amiga Robot OFF.

E-STOP engaged. Clear E-STOP from the command center and/or remote controller.

ERROR mode. Turn the robot OFF and ON again. If the error persists, contact Bonsai Support.

MANUAL mode. You can drive the robot using either the Pendant or the Remote controller.

TELEOP mode. A user is driving the robot via Bonsai Pilot.

AUTONOMY mode. The robot is performing a job sent from Bonsai Pilot.

When you first turn you machine ON, the machine will be likely on E-STOP mode. When ready, clear both RED buttons on control center and the remote controller and you will hear the brakes disengaging and the beacon turning to green.

Use the right joystick to drive your Amiga Flex forward and backwards. Pushing it to one of the sides will make the robot to turn-in-place (zero turn). Letting the joystick go will stop the robot and the motors will bring it to a halt (electric/regenerative braking).

Conversely, the pendant's joystick operate the same way as the remote controller, with the pendant having priority.

The remaining joystick and buttons on the remote controller and the pendant are reserved for upcoming features and not used at the moment.

E-STOP

There are two main safety features equipment on your Amiga Flex: the E-STOP buttons and the bumpers, and each trigger different actions on the robot.

The bumpers trigger a "SOFT E-STOP", where the motors remain powered and the machine will hold position based on electric braking. Once triggered you can clear the Soft E-STOP from Bonsai Pilot, or push and clear the E-STOP button.

The physical E-STOP buttons located on the control center and the remote control shutdown the robot's power, stoping the motors and all peripherals - a "HARD E-STOP". Because the brakes are spring-actuated, they will engage when power is cut. To clear it, release the buttons and wait for the brakes to disengage (you will hear it).

WARNING

In any state, once the E-STOP happens, the robot will immediately stop.

Once both the E-STOP buttons are cleared, the brakes will disengage and the mode will go back to MANUAL.

If an autonomous task was being performed, you will need to also acknowledge the E-STOP on Bonsai Pilot and resume the job.

Brakes

Your Amiga flex is equipped with disc brakes on all 4 wheels. Each caliper is located inside the fork covers and can be accessed removing 3 Allen bolts for adjustments.

For redundancy, the breaks on each side of the robot are independently operated, with brake boxes controlling two wheels each. Because the brakes will engage in case of power-loss, we equipped both boxes with a manual bypass. To manually release brakes, use a 10 mm wrench to push the bolt all the way into the brake box. Unscrew is back to its original position to reactivate the brakes.

CAUTION

When brakes are bypassed, the robot will FREE-WHEEL if a hard E-STOP is triggered (when E-STOP button is pushed). That means that, if on an inclined surface, like a loading ramp, it will move downhill and potentially cause accidents.

Make sure to always re-activate brakes when the bypass is no longer needed.

Transport

Depending on your wheelbase and track width, your Amiga Flex can be transported on truck beds and/or small trailers. We recommend the use of 4 anchoring points pulling in opposite directions to safely transport the Amiga Flex.

We recommend the use of ratchet straps with at least 1000 Lb (450 Kg) of working load. Use the holes on the side of the rails to anchor the hooks.

Once the robot is properly strapped, you can turn the power off and the brakes will provide an extra layer of protection.

Getting used to the Amiga

You are all set. Drive the Amiga Flex around to understand its turning capabilities, how the tires perform on your environment, how to load and unload it, and the operations you want it to perform.

The next step is to setup your account on Bonsai Pilot, create your first routes and fields, and get the work.
