Infinite Monkeys' 2017 Build Diary

[DoubleTrouble]

So we have been tinkering with motors and pulleys this weekend as an alternative to the Ranglebox Saturn-16 gearbox and motor. The reasoning was to see what a family without metalworking equipment could assemble, see if it was useable and give a cost.

So this is this Sunday's build constructed from individual drive components. Total cost was £65.58 plus speed controllers, battery and rx/tx.

After playing around with cheap ESCs, I now buy Turnigy TZ85A at £32 each. Add a Turnigy 5S LIPO @ £18 and we have a fun featherweight robot for less than £150 weaponless and about £200 with an old Dewalt circular saw added.

Does it work? Good enough to have a lot of fun at Insomnia . . .
