Design Refinement for Cordless Drill-Driven Unit

[cardboard]

basically i am looking to build the grey components of this, its a bolt on unit that will allow you to drag the gold legs around using a cordless drill. you plug a standard cordless drill in at the top, (the bracket is symbolic and not representative) this drives the long rod which in turn drives the wheels. the second rod which goes from the back of the drill to the edge of the unit steers it. i have tried to show you how this works in the pictures.

essentially i need to gear the thing down from 1000rpm from the drill to 60 rpm on the wheels but also transmit 120Nm of torque. i can either use the gearing system shown or a worm gear?

also i need to find a CV joint small enough but capable enough of coping with it.

does any of that make sense? lol? any ideas thanks guys

.You could look into using a planetary gearbox to reduce the speed and increase the torque. This type of gearbox will provide the best efficiency and power transmission. You can find planetary gearboxes in various sizes and ratios, so you should be able to find one that meets your requirements. As for the CV joint, you could use a universal joint, which is designed to transmit torque in multiple directions. It should be able to provide the torque you need. Make sure you do some research to make sure the joint is strong enough and suitable for your application.
