You can add electric current sensor & keep track of current once it turned on When you notice sudden change in current it means table encountered a collision
Usually motors will draw more current when we tried to add more load.

Others method is to use rotatory encoders there you need to track change in speed during the collision.

There are plenty of methods You can try:
Using mpu6050, lasers, accelerometer, etc.

One correction… you didn’t make this, the carpenter did. You bought items 😂

Regarding anti collision, if u can read current consumption frm actuator, that can work without introducing a sensor.
Advantage:
1. No BOM change
2: cost remain same and in turn as u are adding a feature, u can add more profit.
3. Complexity do not increase.

This approach we utilize in designing automotive door window up feature called anti-pinch. So we have a motor which moves glass in car windows up-down. ECU continuously read current from motors. If motor see something coming on their way while going up, it trying to push and apply power which in turn suddenly increase current consumption.
ECU detect change in current and cut motor operation.
Hope this helps...

I got adjustable table in the kitchen, moving up and down with the cooker and basin plus space in between because I an wheelchair user, when I stand, I just move it up.

6000N x 2 actuator.. they can pus a quintal of weight... Even 2 1500N would have done job.. can save 1000-1500 per actuator...
Also, we can work with aluminium profile to make table.. lighter weight.. saves labour charges and can be dismantled, parts can be changed to change length and width or the table anytime..

Good stuff.Always great to build your own things especially when you know how they work then you know how to fix them if needed.

[GOURAB_DAS_]

Appreciate you and your teams hard work 😊☺️

[JanJeronimus]

Great project! Are you going to add a sensor so you can measure the height so you can easy go to some configurable heights?

[VishalSoniIndia]

Add current sensor, when motor will draw current when something stuck between it, release it in opposite directions

[DiyintheGhetto]

Awesome build and you and your team did a great job.

This might just be one of my favorite youtube videos ever. Interesting and very cool!

[Delali]

This adjustable table design is really amazing. I could really use one these tables as my YouTube table for making tutorials.

I like the wood finish.

[femgnsi]

I'm a generally mean person and tend to hate everyone, equally.
The presenter in this video has great charisma and explains things very well and I thoroughly enjoyed this video.
Great job.

Just for ":Hydraulic Gas Lift for height adjustable table". I think gas lift for table is a better mechanism as it does not require any electricity to adjust height, and i feel it change height faster than the electric actuator.

[azimalif]

They probably measure the current consumption to stop the table from damaging other objects. If there are obstructions the motors will suddenly consume more power, if you detect that from the wire in-between the motor and the power supply, you can stop it. Waiting for an update video.

[jeetz]

Awesome, getting the adjustable table in India is so costly. Great idea to make it by own. Very great 💙

[jimbooth]

Very nice job and project. making something so useful and using the esp32 is so much more interesting than many projects on youtube. Really enjoy your channel.

[drelectronics]

Instead of using button use touch sensors and as u added support in between it looks like it will break ur leg if u mistakenly keep between them so yeah better to add preassure sensor

Those actuators can be a diy one. With some nuts and long bolts. Those actuators are way too costly.
