Time for another update!
I'm further refining the design but I decided I need to get the core parts of the electronics system bought and tested. With that in mind I've created the following diagram to show how everything will be connected together:
- A 5S1P 18.5V 4500mAh battery powers the robot, its a Turnigy Nano-tech and I'll charge it via an iMAX B6AC.
- I'm not sure which connector I'll use for the removable link as I want to standardise on XT60s though out but accidentally putting the removable link across the battery is something I'd then worry about.
- The Wago 862-0504 is a spring loaded terminal block for 12 AWG to 20 AWG wire which consists of 4 poles with 4 connections each with individual springs. It should keep the wiring neat and tidy as well as safe.
- The power indicator will be something like a 10mm red LED with a suitable resistor connected across the battery.
- I've bought a DX5e 2.4GHz DMS2/DMSX transmitter and a OrangeRX R710 receiver to control the robot.
- I've decided to use TZ-85A brushless ESC which have been modified to drive brushed motors for the moment. The price differential is insane and the modification looks pretty simple. I may swap them out for a custom designed motor controller at a later date.
- The top two TZ-85As are for driving the motors and have an external v-tail mixer although I'm not sure this is required with the use of TX mixing and the latest TZ-85A firmware.
- The bottom TZ-85A is for the lifter arm and is connected to a custom designed limiter.
I've now bought most of these parts and I'm going to see if I can get the TZ-85As modified, connected up and tested.
